This inverter is started and stopped based on operation command signals STX1 and STX2, and frequency controlled based on frequency command signals fx1 and fx2. A variable frequency and a variable voltage are supplied to the No. 1 and No. 2 booster pump motors IM1 and IM2 described above. CONS1 and CONS2 are the operators respectively, who set parameters such as the acceleration time of the inverter and the overcurrent tripping level, and individually command the operation to stop. ELB1 and ELB2 are earth leakage circuit breakers that protect the leakage current of the inverter and the motor installed behind them.

CU is a control device, which is composed of microprocessor CPU, input and output ports PIO-1~PIQ-5, analog input and output ports D/A, memory M, and regulated power supply circuit AVR. In addition, programs necessary for the operation of the pressurized water supply system are stored in the above-mentioned memory M. SS is a stop switch, and when the SS is turned ON, power is supplied to the CU via the AVR. Also, turn OFF to cut off the power supply, and stop if it is running. Z is the relay drive unit, through the software processing of the CPU, the ON and OFF signals are output from PIO-4 to Z, and the relays STX1, STX2, X1, and X2 are opened and closed.

The relays STX1 and STX2 are the operation stop signals of the above-mentioned inverters, the relay X1 outputs the operation signals to other pressurized water supply system control boards, and the relay X2 outputs the response signals. In the case of the middle layer area, since it is transmitted to the lower layer and the upper layer, two signals are required. Other than that, only one signal is enough. In addition, the reception of the operation signal S11 or the response signal S12 from other pressurized water supply system control boards is received by relays X3 and X4, and these signals are input from PIO-5.

In addition, SW is a switch for setting the control parameters of the pressurized water supply system shown in FIGS. 5 to 7 . Their values are fetched from PIO-3 and stored in memory. The signals of the pressure sensor for detecting the pressure head on the water supply pipe side and the pressure sensor for detecting the pressure head on the discharge side are taken in by the analog port A/D and stored in the memory. For example, it is converted to 0 to 100m and saved.

5 is an operation characteristic diagram showing the operation control and parameters of the pressurized water supply system installed in the lower floor area, the left side shows the suction side, and the right side shows the discharge side. The suction side refers to the pressure head of the water supply pipe for tap water, SLL is the pressure head used to stop the pump when the pressure head of the water supply pipe drops, and SL indicates the recovery pressure head. In addition, in this embodiment, it is assumed that SLL is 7 m and SL is 10 m. In addition, SHH is a parameter for feeding water only with the pressure of the water supply pipe without operating the booster pump when the pressure head of the water supply pipe is sufficiently high, and SH represents the recovery pressure head. In this embodiment, SHH is set to the discharge-side predetermined pressure H0 on the right side or a value slightly higher than it. Set SH to be several m lower than SHH.

The discharge side is associated with a pump performance curve representing the operation of the booster pump, and represents a parameter. The vertical axis represents the full head, and the horizontal axis represents the discharge amount (equivalent to the maximum water consumption). Curve A is the pump Q-H performance curve when the inverter frequency fmax (100% frequency) makes the pump run. Curve F represents the resistance of itself and the water supply piping etc. when the booster pump is operated to feed water in the zone using the booster water supply system in the lower layer zone. In addition, when water is supplied to this area, the desired water quantity is the above-mentioned discharge quantity (maximum water quantity) Q0, and the desired pressure head total head H0. The Q0 and H0 are design values, preferably designed to be at the intersection point O of the pump Q-H performance curve A and the resistance curve F, but may be designed to be smaller than the intersection point O on the resistance curve F.

In addition, curves B and C are the Q-H performance when the inverter frequency is changed to f1 and fmin (minimum frequency) to operate the pump. The frequency of the inverter is stepless, and the corresponding curves can be drawn between the curves A and C, and for the convenience of explanation, these curves are represented by curves B and C. In addition, these curves mean that when the inverter frequency is operated at f1, the Q-H performance curve of the pump is B and the pump discharge is Q1, and when the inverter frequency is operated at fmin, the Q-H performance curve of the pump is C, The pump discharge is 0. On this basis, when the water consumption changes from 0 to Q0, the booster pump controls the operation of the pressure head by following the resistance curve F and according to the output fmin to fmax from the inverter, using a method called constant end pressure control . When performing this control, on the curve F as the target pressure, set the desired value when the discharge volume is 0 as H00 (corresponding to the inverter frequency fmin), and set the desired value as H0 (corresponding to the inverter frequency fmin) when the discharge volume is Q0 (corresponding to corresponding to the inverter frequency fmax). That is, by approximating the curve F between H00 and H0 with a straight line, it is either treated as a function or used as a table.

On the other hand, when a plurality of pumps are operated in tandem, it is preferable to operate with constant discharge pressure control in order to suppress pressure fluctuations other than the highest level. Therefore, in the discharge amount 0 to Q0, when H0 constant control is performed, it becomes a horizontal line G. The frequency of the inverter at the discharge of 0 is f2, the Q-H performance curve of the pump is E, and the intersection point with the horizontal line G where H0 is constant is O11.

Furthermore, PON is the starting pressure head of the booster pump (generally set to be close to H00), and POFF is the stop pressure head of the booster pump (generally set to be higher than PON). Qmin is the discharge amount for stopping the booster pump when the amount of water is too low, and is detected by the above-mentioned flow detection means. Furthermore, this state is detected, and the inverter frequency is raised to foff in order to realize pressure accumulation in the pressure tank immediately before stopping, and then stops. At this time, the pump Q-H performance curve is D. The stop pressure head becomes POFF. In addition, the control on the suction side mentioned above is performed by the detection of the pressure sensor PS11, and the control on the discharge side is performed by the detection of the pressure sensor PS12.

Fig. 6 is an operation characteristic diagram showing the operation control and parameters of the pressurized water supply system installed in the middle layer area, the left side shows the suction side, and the right side shows the discharge side. The unnecessary SHH and SH shown in FIG. 5 are omitted on the suction side on the left. The discharge side is the same as that in Fig. 5, and the design values Q0 and H0 are the values required for water supply to the middle zone. Fig. 7 is an operation characteristic diagram showing the operation control and parameters of the pressurized water supply system installed in the high-rise area, the left side shows the suction side, and the right side shows the discharge side. The suction side on the left is the same as in Fig. 6 . On the discharge side, the horizontal line G at the time of constant discharge pressure control, which is unnecessary for the highest level area, is omitted from Fig. 5, and the design values Q0 and H0 are values required for water supply to the high-level area.

Specific implementation in this embodiment configured as above will be described. The pressurized water supply system in this embodiment is configured to transmit and receive operation and stop signals between the pressurized water supply systems of the lower, middle and upper floors. In addition, in this embodiment, for the convenience of explanation, it is divided into low level, middle level, and high level, and no matter whether it is two booster control systems of the lower level and the middle level, or divided into four or more booster water supply systems, it can be implemented in the same way.

That is, between the lower layer and the middle layer, the operation signal S11 is sent from the lower layer to the middle layer, the response signal S12 is received, the operation signal S13 is sent from the middle layer to the lower layer, the response signal S14 is received, and the operation or stop signal is mutually transmitted and received.

For example, when water is used in the lower layer and no water is used in the middle layer, signals S11 and S12 are sent, and the pressurized water supply system for the lower layer operates as described above to perform operation. That is, the booster pumps installed in each area in this embodiment are capable of starting and stopping in accordance with the pressure as described above, and at the same time, transmit and receive operation signals indicating starting and stopping between the layers. Moreover, when water is used in the middle layer area and no water is used in the lower layer area, at first, the start-up condition of the pressurized water supply system in the middle layer area is established, and its booster pump starts to run.

Here, in this embodiment, in this case, the operation signal S13 is sent to the pressurized water supply system for the lower floor area. Then, the pressurized water supply system for the low-floor area that has received this signal transmits the response signal S14, and starts the operation irrespective of whether or not the activation condition possessed by itself is established. Then, the signal S11 is operated accordingly, and the response signal thereof is received. Thus, in this embodiment, the interlocking operation of each zone is performed. Explain why.

When water is used in the middle layer, especially when the water is used rapidly, etc., when a sudden pressure fluctuation occurs, even if it is assumed that water is used in the lower layer, when the booster pump is starting, the above-mentioned pressure fluctuation, according to its own Depending on the start and stop conditions, the booster pump may stop. In the case where water is subsequently also used in the lower layer, the activation condition is satisfied again and activation is performed, which may cause unnecessary repetition of activation and stop of the booster pump. That is, there is a possibility of an oscillation phenomenon caused by a sudden pressure fluctuation. Therefore, in the present embodiment, as mentioned above, when water is used in the middle layer and the pressurized water supply system for the middle layer area is started, it has nothing to do with whether the starting condition of the pressurized water supply system for the lower layer area is established. Start-up of pressurized water system. Thereby, the above-mentioned hunting phenomenon can be prevented.

In addition, although the description has been made here between the middle layer and the lower layer, the same applies to the case where water is used in the upper layer. That is, when water is used in the upper floors and the activation condition of the pressurized water supply system for the upper floors is satisfied, an operation signal S23 is sent from the upper floors to the middle floors. The pressurized water supply system for the middle layer area that has received the operation signal S23 sends a response signal S24 to the upper layer, and at the same time, regardless of whether the activation conditions it possesses are established, the operation starts. When the operation of the upper layer is started in this way, the reason for starting the operation is the same as that described above regardless of whether the activation condition of the lower layer itself is satisfied.

In addition, in this case, the operation signal S13 is sent to the lower floor because the pressurized water supply system for the middle floor area is activated. Furthermore, as described above, in the lower layer, the response signal S14 is sent to the middle layer, and at the same time, the operation is started irrespective of whether or not its own activation condition is satisfied. That is, if the operation of the upper stage is performed, the operation of the lower stage is started in conjunction with it, so as to prevent the oscillation phenomenon with respect to the pressure fluctuation.

Next, an embodiment in which an interlocking stop function is added to the above-mentioned embodiments will be described. Firstly, water is used in the middle zone, and when there is no water in the low zone, first, the starting condition of the pressurized water supply system for the middle zone is established, and its booster pump starts to run. Furthermore, an operation signal S13 is sent to the pressurized water supply system for the lower floor area. The low-rise area that has received this signal sends a response signal S14 with the pressurized water supply system, and at the same time, regardless of whether its own activation conditions are established, the operation starts. Accordingly, the operation signal S11 is sent, and the response signal thereof is received. Even if there is no water in the lower layer, the stop condition of the pressurized water supply system here is satisfied, and when S13 receives the stop signal from the pressurized water supply system for the middle layer, the pressurized water supply system for the lower layer continues to operate. In addition, this embodiment is also applicable to the middle layer and the upper layer.

Furthermore, an embodiment in which the lower layers are first activated before the self activation will be described. This situation is also the case where there is water in the middle zone and there is no water in the low zone. First, if the start-up condition of the pressurized water supply system for the middle zone is established, then in this embodiment, firstly, the pressurized water supply system is used for the low zone. The system sends a running signal S13. Then, the pressurized water supply system for the low-rise area that received this signal sends a response signal S14, and starts the operation irrespective of whether its own activation conditions are met or not. Correspondingly send the operation signal S11. The pressurized water supply system for the middle layer area starts to operate upon receiving the operation signal S11, and returns a response signal to the pressurized water supply system for the low layer area. That is, thereby, it is possible to more reliably start the operation from the zone pressurization system, and it is possible to cope with the above-mentioned pressure fluctuation. In addition, this embodiment is also applicable to the middle layer and the upper layer.

Furthermore, when both the pressurized water supply system is used for the operation of the lower layer and the middle layer area, even if there is no water in the lower layer, if there is water in the middle layer, the lower layer will continue to operate. If there is no water in the middle layer and stop, then Then the embodiment in which the lower layer is also stopped. That is, when water is used in the middle layer area and no water is used in the lower layer area, first, the start-up condition of the pressurized water supply system for the middle layer area is established, and the booster pump starts to run, and at the same time, an operation signal is sent to the pressurized water supply system for the low layer area S13, when the pressurized water supply system for the low-rise area receiving the signal sends a response signal S14, it starts running irrespective of whether its own start-up condition is established or not. Accordingly, the operation signal S11 is sent, and the response signal thereof is received. Then, even if there is no water in the lower layer, the stop condition of the pressurized water supply system here is established, but when the S13 of the operation stop signal is received from the pressurized water supply system for the middle layer area, the pressurized water supply system for the lower layer area continues to operate. If there is no water in the pressurized water supply system for the middle zone and the stop condition is met, it will stop, and the operation signal S13 will be released. As a result, the pressurized water supply system in the lower layer area was shut down. In addition, the same applies to the case of a higher layer or a higher layer. That is, when the operation signal is received from the upper layer, it does not stop even if its own stop condition is satisfied, and stops when the operation signal S13 is released from the upper layer. Thereby, it is possible to further prevent repeated stoppage of operation of the pressurized water supply system with respect to pressure fluctuations.

Furthermore, an embodiment in which the above-described embodiments are combined is also effective.

That is, when water is used in the lower layer and no water is used in the middle layer, signals S11 and S12 are sent, and the pressurized water supply system for the lower layer operates as described above to perform operation. When water is used in the mid-level area and no water is used in the low-level area, first, the start-up condition of the pressurized water supply system for the middle-level area is established, and at the same time when the booster pump starts to operate, a stop signal is sent to the pressurized water supply system for the low-level area S13. The pressurized water supply system for the lower floor area that has received this signal sends the response signal S14, and starts running irrespective of whether its own activation conditions are established or not. Correspondingly, the signal S11 is operated and its response signal is received.

Moreover, in this embodiment, even if there is no water in the lower layer subsequently, the stop condition of the pressurized water supply system here is established, but when S13 receiving the operation stop signal from the pressurized water supply system for the middle layer area, the booster water supply system for the lower layer area is stopped. The pressurized water supply system continues to operate. If the pressurized water supply system for the above-mentioned middle layer area does not have water, the stop condition is established and then stops, and the S13 of the operation stop signal is released. As a result, the pressurized water supply system in the lower layer area was shut down.

Furthermore, the above-mentioned embodiments can also be combined as follows.

That is, when water is used in the middle zone and no water is used in the low zone, first, if the activation condition of the pressurized water supply system for the middle zone is satisfied, an operation signal S13 is sent to the pressurized water supply system for the low zone. The lower floor area that has received this signal sends a response signal S14 to the system with pressurization, and starts operation irrespective of whether its own activation conditions are met or not. Signal S11 is activated accordingly. If the pressurization system for the middle layer area receives the operation signal S11, it starts to operate, and returns a response signal to the pressurization system for the lower layer area.

Moreover, even if there is no water in the lower layer subsequently, the stop condition of the pressurized water supply system here is established, but when S13 of the operation stop signal is received from the pressurized water supply system for the middle layer area, the pressurized water supply system for the lower layer area continues to operate, If the above-mentioned pressurized water supply system for the middle layer area does not have water, the stop condition is met, then stop, and S13 of the operation stop signal is released. As a result, the pressurized water supply system in the lower layer area was shut down.

Furthermore, one embodiment among the present examples will be described.

The use of water in the high-rise zone has nothing to do with the use of water in the middle and low-rise zones. First, if the activation condition of the pressurized water supply system for the high-rise zone is established, an operation signal S23 is sent to the pressurized water supply system for the middle zone. The pressurized water supply system for the middle layer area having received this signal sends a response signal S24, and at the same time sends an operation signal S13 to the pressurized water supply system for the lower layer area. The pressurized water supply system for the low-rise area that has received this signal sends the response signal S14, and starts running irrespective of whether its own activation conditions are established or not. Signal S11 is activated accordingly. If the pressurized water supply system for the middle layer area receives the operation signal S11, it will start running regardless of whether the start condition is established, send the operation signal S21 to the pressurized water supply system for the high-level area, and return its response to the pressurized water supply system for the low-level area Signal S12. If the pressurized water supply system for high-rise areas receives the operation stop signal S21, it starts operation and sends a response signal S22. Then, when water is used in the high-rise, the pressurized water supply system here is running, and there is no water in the middle and low floors, regardless of whether the stop condition is established, it continues to run.

Furthermore, one embodiment among the present examples will be described.

The use of water in the high-rise zone has nothing to do with the use of water in the middle zone and the low-rise zone. First, if the activation condition of the pressurized water supply system for the high-rise zone is established, a stop signal S23 is sent to the pressurized water supply system for the middle zone. The pressurized water supply system for the middle layer area having received this signal sends a response signal S24, and at the same time sends an operation stop signal S13 to the pressurized water supply system for the lower layer area. The pressurized water supply system for the low-floor area that has received this signal starts operating regardless of whether its own activation conditions are satisfied or not at the same time as sending the response signal S14. Signal S11 is activated accordingly. If the pressurized water supply system for the middle layer area receives the operation signal S11, it will start running irrespective of whether the start conditions are established, send a stop signal S21 to the pressurized water supply system for the high-level area, and return to the pressurized water supply system for the low-level area It responds to signal S12. When the pressurized water supply system for high-rise areas receives the operation signal S21, it starts operation and sends a response signal S22. Then, when water is used in the high-rise, the pressurized water supply system here is running, and there is no water in the middle and low floors, regardless of whether the stop condition is established, it continues to run.

Moreover, if there is no water in the high-rise area, the stop condition is established, and the high-rise area is stopped with the pressurized water supply system. The operation stop signal S23 is released simultaneously with the stop. At this time, the lower zone has nothing to do with whether there is no water and whether the stop condition is established, and if it is being sent the operation stop signal S13 from the middle layer, it will continue to run. If there is no water in the middle zone and the stop condition is established, then the middle zone is stopped with a pressurized water supply system. Simultaneously with the stop, the operation stop signal S13 is released. The pressurized water supply system for the lower floor is stopped when the stop condition is satisfied by the cancellation of the operation stop signal S13.

Furthermore, one embodiment among the present examples will be described.

The pressure head parameter is set, and when it is not the lowest pressurized water supply system, it sends a start command to the lower pressurized water supply system that is established earlier than its own start condition. For example, in the middle layer, in the discharge-side pump operation characteristic diagram of Fig. 6, the booster pump starting pressure head PON of the booster water supply system for the middle layer area is several meters higher, and the booster pump of the booster water supply system for the lower layer area is installed Starting pressure head PONH. In this way, before the water supply pressure head becomes the activation condition for the middle floor, it becomes the activation condition for the lower floor. Accordingly, the operation stop signal S13 is transmitted from the middle layer to the lower layer. When the lower layer receives this signal, it returns the response signal S14, starts the operation regardless of whether its own activation condition is met, and transmits the operation stop signal S12.

Similarly, in the discharge-side pump operation characteristic diagram of FIG. 7 , the boost pump starting pressure head PON of the booster water supply system for the middle layer is set several meters higher than the booster start pressure head PON of the booster water supply system for the middle layer. In this way, before the water supply pressure head becomes the activation condition for the upper floor, it becomes the activation condition for the middle floor. Therefore, an operation stop signal S23 is sent from the upper layer to the middle layer. The middle layer that received this signal returns the response signal S24, regardless of whether its own activation conditions are met, starts the operation, and transmits the operation stop signal S22.

In addition, as another embodiment, a timer may also be provided. For example, if the starting condition is established, the timer is started to count, and the booster pump is started when the time is up. If there is no water in the lower and middle floors, water is used in the upper floors, and the activation condition here is met, then the pressurized water supply system for the upper floors sends a stop signal S23 to the middle floors while starting the timing of the timer. The middle layer that has received this signal starts counting of the timer for the start regardless of whether the activation condition is established or not, and at the same time transmits the operation stop signal S13 to the lower layer. The lower layer that has received this signal starts counting of the timer for activation regardless of whether the activation condition is met or not. If these timers are pre-set to for example high level 5 seconds, middle level 3 seconds, low level 0 second, then low level starts running, after 3 seconds, middle level, after 5 seconds, high level starts running in sequence.

Furthermore, one embodiment among the present examples will be described.

In this embodiment, during the operation of multiple systems of pressurized water supply systems from the low-rise area to the high-rise area, the highest-order pressurized water supply system performs variable-speed operation accompanied by fluctuations in water consumption. The water supply system performs fixed operation at the highest speed.

For example, if there is no water in the lower and middle floors, and water is used in the upper floors, and the starting conditions here are established, then the pressure control operation shown in Fig. The middle layer sends an operation stop signal S23. The middle layer that has received this signal sends an operation stop signal S13 to the lower layer regardless of whether the start condition is met or not. The lower layer that has received this signal operates at the highest speed of the inverter regardless of whether the start condition is established or not, and sends the operation stop signal S12 to the middle layer. The middle layer that receives this signal runs at the inverter's highest speed.

As described above, according to this embodiment, when water is concentrated in a part of an area or in a local area for a short period of time, an interlocking operation is performed so as to have coordination as a whole system. Furthermore, even when a problem such as a drop in water supply pressure occurs in a part of the area or in a local area, it is possible to prevent the oscillation phenomenon of starting and stopping in each system for the low floor, the middle floor, and the high floor.

Moreover, it is possible to solve problems such as water supply pressure drop in a part of the area or in a local area, and at the same time, a stable and highly reliable interlocking operation system between the pressurized water supply systems can be realized.

[Example 2]

Next, Embodiment 2 of the present invention will be described.

In the pressurized direct-connected water supply system where multiple devices are installed in parallel in the low-level area, and the areas above the middle-level area are set in series, for example, because each Each pressurized water supply system in the area operates independently, so in the case of concentrated water in a part of the area or in a short period of time, it cannot perform linked operation, lacking coordination as a whole system, and water supply may occur in a part of the area or locally Pressure drop problem. If there is a lack of coordination, each of the systems for the low-rise area, the middle-level, and the high-level may have a start-stop oscillation phenomenon.

The basic structure of this embodiment is the same as the system diagram of the pressurized water supply system for middle and high-rise buildings in Fig. 1 . However, although not shown here, the booster pump directly connected to the water supply pipe for tap water in this embodiment is provided in parallel so that it can cope with a large amount of water supply. As a result, as the demand end in the lower floor area, not only the faucets 5-1a, 5-1b, 5-1c, but also the water supply of a large amount of water required by the faucets 5-2a, 5-2b, and 5-2c can be handled. Therefore, although not shown in the figure, the water supply pipe branch pipe 2 for tap water is branched into, for example, 2-1 and 2-2, and is directly connected to the main pipes of the respective booster pumps 4-1 and 4-2.

Here, the same as in Embodiment 1, between the pressurized water supply system 4 (4-1, 4-2) in the low-level area and the pressurized water supply system 6 in the middle-level area, the pressurized water supply system 6 is used to transmit the representation of the lower layer to the middle-level area. The operation signals S11 (for No. 1 equipment) and S15 (for No. 2 equipment) of the district pressurized water supply system 4-1 or 4-2 are running, and the response signal S12 (for No. 1 equipment) is sent to these signals. ) and S16 (for equipment No. 2). In addition, the operation signals S13 (for No. 1 equipment) and S17 (for No. 2 equipment) representing the state of the pressurized water supply system 6 in the middle layer area are also sent and received, and the response signals S14 (for No. 1 equipment) and S18 (for equipment No. 2). And, same as embodiment 1, between the pressurized water supply system in the middle floor area and the high-rise area, the operation signal S21 and the response signal S22 of the signal that the pressurized water supply system in the middle floor area is running are sent and received, indicating that the high-rise area Use the operating signal S23 of the state that the pressurized water supply system is operating and the response signal S24 of this signal. By sending and receiving these signals to each other to realize a linked operation system, even in the case of sudden pressure fluctuations, it is possible to perform stable water supply without oscillation. In addition, these signals may use a communication line or may be wireless.

Each embodiment configured as above will be described.

In one implementation of this embodiment, as mentioned above, the pressurized water supply system for the lower layer area is set in parallel, so that each pressurized system can send and receive operation signals to each other, that is, between the lower layer and the middle layer, from the lower layer to the middle layer The operation signal S11 is sent, and the response signal S12 is received, and the operation signal S13 is sent from the middle layer to the lower layer, and the response signal S14 is received, and the signals are mutually transmitted and received.

And, when water is used in the lower layer area and no water is used in the middle layer area, signals S11 and S12 are sent, and the pressurized water supply system for the lower layer area operates as described above, and operates. When water is used in the middle zone and no water is used in the low zone, first, the start-up condition of the pressurized water supply system for the middle zone is established, and at the same time when the booster pump starts running, an operation signal is sent to the pressurized water supply system for the low zone S13 . The pressurized water supply system for the lower floor area that has received this signal sends the response signal S14, and starts running irrespective of whether its own activation conditions are established or not. Accordingly, the operation signal S11 is sent, and the response signal thereof is received. In this way, the linked operation is performed.

In other implementations of this embodiment, a linkage stop function is added to the above-mentioned implementations. That is, if the pressurized water supply system for the low-level area is installed in parallel, when water is used in the middle-level area and no water is used in the low-level area, first, the start-up condition of the pressurized water supply system for the middle-level area is established, and the booster pump starts to run. The lower zone uses the pressurized water supply system to send a running signal S13. The pressurized water supply system for the lower floor area that has received this signal sends the response signal S14, and starts running irrespective of whether its own activation conditions are established or not. Accordingly, the operation signal S11 is sent, and the response signal thereof is received. Then, even if there is no water in the lower zone, the stop condition of the pressurized water supply system here is established, but when the operation signal S13 is received from the pressurized water supply system for the middle zone, the pressurized water supply system for the lower zone continues to operate. In this way, the linked operation is performed.

Furthermore, in another embodiment of this embodiment, in the above embodiment, before starting itself, the pressurized water supply system for the lower floor area is first activated. That is, if the pressurized water supply system for the low-level area is installed in parallel, water is used in the middle-level area, and no water is used in the low-level area. Send the operation signal S13. The pressurized water supply system for the lower floor area that has received this signal sends the response signal S14, and starts running irrespective of whether its own activation conditions are established or not. Accordingly, the operation signal S11 is generated. The pressurized water supply system for the middle layer area will start to operate if it receives the operation signal S11, and returns its response signal to the pressurized water supply system for the low layer area.

Furthermore, in other implementations of this embodiment, in the above-mentioned embodiment, when both the pressurized water supply system for the low-level area and the middle-level area are in operation, the pressurized water supply system for the low-level area is set in parallel, even if the pressurized water supply system for the low-level area No water is used, but if water is used in the middle layer, the lower layer will continue to operate, and if the middle layer stops without water, then the lower layer will also stop. That is, when water is used in the middle layer area and no water is used in the lower layer area, first, the start-up condition of the pressurized water supply system for the middle layer area is established, and when the booster pump starts to operate, an operation signal is sent to the pressurized water supply system for the low layer area S13. The pressurized water supply system for the lower floor area that has received this signal sends the response signal S14, and starts running irrespective of whether its own activation conditions are established or not. Correspondingly, the signal S11 is operated and its response signal is received. Then, even if there is no water in the lower layer, the stop condition of the pressurized water supply system here is established, but when the operation signal S13 is received from the pressurized water supply system in the middle layer area, the pressurized water supply system in the lower layer area continues to operate. The pressurized water supply system for the district uses no water, and if the stop condition is met, it stops, and the operation signal S13 is released. As a result, the pressurized water supply system in the lower layer area was shut down.

Furthermore, other embodiments of the present embodiment are combinations of the above-described embodiments. Set up the pressurized water supply system for the lower zone in parallel, use water in the low zone, and send signals S11 and S12 when there is no water in the middle zone, and the pressurized water supply system for the low zone acts as described above and operates. When water is used in the middle zone and no water is used in the low zone, at first, the activation condition of the pressurized water supply system for the middle zone is established, and when the booster pump starts running, an operation signal S13 is sent to the pressurized water supply system for the low zone. The pressurized water supply system for the lower floor area that has received this signal sends the response signal S14, and starts running irrespective of whether its own activation conditions are established or not. Correspondingly, the signal S11 is operated and its response signal is received.

Then, even if there is no water in the lower layer, the stop condition of the pressurized water supply system here is established, but when the operation signal S13 is received from the pressurized water supply system in the middle layer area, the pressurized water supply system in the lower layer area continues to run. If there is no water in the pressurized water supply system and the stop condition is met, it will stop, and the operation signal S13 will be released. As a result, the pressurized water supply system in the lower layer area was shut down.

Furthermore, other embodiments of the present embodiment are combinations of the above-described embodiments. Set up the pressurized water supply system for the low-level area in parallel, when water is used in the middle-level area, and there is no water in the low-level area, first, if the start-up condition of the pressurized water supply system for the middle-level area is satisfied, the operation will be sent to the pressurized water supply system for the low-level area Signal S13. The pressurized water supply system for the lower floor area that has received this signal sends the response signal S14, and starts running irrespective of whether its own activation conditions are established or not. Signal S11 is activated accordingly. The pressurized water supply system for the middle layer area starts to operate upon receiving the operation signal S11, and returns a response signal to the pressurized water supply system for the low layer area.

Then, even if there is no water in the lower layer, the stop condition of the pressurized water supply system here is established, but when the operation signal S13 is received from the pressurized water supply system in the middle layer area, the pressurized water supply system in the lower layer area continues to run. If there is no water in the pressurized water supply system and the stop condition is met, it will stop, and the operation signal S13 will be released. As a result, the pressurized water supply system in the lower layer area was shut down.

Furthermore, in other implementations of this embodiment, the pressurized water supply system for the low-rise area is set in parallel, and the water used in the high-rise area has nothing to do with the use of water in the middle and low-rise areas. First, if the pressurized water supply system for the high-rise area When the starting condition of the system is established, an operation signal S23 is sent to the pressurized water supply system for the middle layer area. The pressurized water supply system for the middle layer area having received this signal sends a response signal S24, and at the same time sends an operation signal S13 to the pressurized water supply system for the lower layer area. The pressurized water supply system for the lower floor area that has received this signal sends the response signal S14, and starts running irrespective of whether its own activation conditions are established or not. Signal S11 is activated accordingly. If the pressurized water supply system for the middle layer area receives the operation signal S11, it will start running regardless of whether the start condition is established, send the operation signal S21 to the pressurized water supply system for the high-level area, and return its response to the pressurized water supply system for the low-level area Signal S12. The pressurized water supply system for high-rise areas starts to operate upon receiving the operation signal S21, and at the same time, sends a response signal S22. Then, when water is used in the upper floors, the pressurized water supply system here is running, even if there is no water in the middle and lower floors, it does not matter whether the stop condition is established or not, and continues to run.

Furthermore, in other implementations of this embodiment, the pressurized water supply system for the low-rise area is set in parallel, and the water used in the high-rise area has nothing to do with the use of water in the middle and low-rise areas. First, if the pressurized water supply system for the high-rise area When the starting condition of the system is established, an operation signal S23 is sent to the pressurized water supply system for the middle layer area. The pressurized water supply system for the middle layer area having received this signal sends a response signal S24, and at the same time sends an operation signal S13 to the pressurized water supply system for the lower layer area. The pressurized water supply system for the lower floor area that has received this signal sends the response signal S14, and starts running irrespective of whether its own activation conditions are established or not. Signal S11 is activated accordingly. If the pressurized water supply system for the middle layer area receives the operation signal S11, it will start running regardless of whether the start condition is established, send the operation signal S21 to the pressurized water supply system for the high-level area, and return its response to the pressurized water supply system for the low-level area Signal S12. The pressurized water supply system for high-rise areas starts to operate upon receiving the operation signal S21, and at the same time, sends a response signal S22. Then, water is used in the high-rise area, and when the pressurized water supply system here is running, it has nothing to do with not using water in the middle and low floors, whether the stop condition is set up, and continues to run. If there is no water in the high-rise area, the stop condition is established, and the high-rise area is stopped with the pressurized water supply system. The operation signal S23 is canceled simultaneously with the stop. At this time, the lower layer has nothing to do with whether there is no water or whether the stop condition is established, and if the operation signal S13 is sent from the middle layer, it will continue to run. If there is no water in the middle zone and the stop condition is established, then the middle zone is stopped with a pressurized water supply system. The operation signal S13 is canceled simultaneously with the stop. The pressurized water supply system for the lower floor area will stop if the stop condition is satisfied according to the cancellation of the operation signal S13.

Furthermore, in other implementations of this embodiment, the pressure water head parameter is set so that if it is not the lowest pressurized water supply system, a start is sent to the lower pressurized water supply system that is established earlier than its own start condition. instruction. For example, in the middle layer, in the discharge-side pump operation characteristic diagram of Fig. 6, the booster pump starting pressure head PON of the booster water supply system for the middle layer area is several meters higher, and the booster pump of the booster water supply system for the lower layer area is installed Starting pressure head PONH. In this way, before the water supply pressure head for the middle floor becomes the activation condition, it becomes the activation condition for the lower floor. Accordingly, the operation signal S13 is transmitted from the middle layer to the lower layer. Receiving this signal, the lower layer returns a response signal S14, and starts running regardless of whether its own start conditions are met, and transmits a running signal S12. Similarly, in the discharge-side pump operation characteristic diagram of FIG. 7 , the boost pump starting pressure head PON of the booster water supply system for the middle layer is set several meters higher than the booster start pressure head PON of the booster water supply system for the middle layer. In this way, before the pressure head for the upper layer becomes the activation condition, it becomes the activation condition of the middle layer. Accordingly, the operation signal S23 is transmitted from the upper layer to the middle layer. The middle layer that has received this signal returns the response signal S24, regardless of whether its own activation conditions are established, starts the operation, and transmits the operation signal S22.

In addition, as another embodiment, a timer may also be set. For example, if the starting condition is established, the timer is started to count, and the booster pump is started when the time is up. If there is no water in the lower and middle floors, water is used in the upper floors, and the activation condition here is established, then the pressurized water supply system for the upper floors sends the operation signal S23 to the middle floors while starting the timing of the timer. The middle layer that has received this signal starts counting of the timer for the start regardless of whether the activation condition is established or not, and at the same time transmits the operation signal S13 to the lower layer. The lower layer that has received this signal starts counting of the timer for activation regardless of whether the activation condition is met or not. If these timers are pre-set to for example high-level 5 seconds, middle-level 3 seconds, low-level 0 seconds, then low-level starts running, after 3 seconds, middle-level, after 5 seconds, high-level, start running like this sequentially.

Furthermore, in other implementations of this embodiment, during the operation of multiple systems of pressurized water supply systems from the low-rise area to the high-rise area, the highest-level pressurized water supply system performs variable-speed operation accompanied by fluctuations in usage. Therefore, the lower pressurized water supply system performs constant operation at the highest speed. For example, if there is no water in the lower and middle floors, and water is used in the upper floors, the start-up condition here is established, and since the pressurized water supply system for the upper floors does not have an operating signal from the upper level, the pressure control operation shown in Figure 7 is carried out, and the pressure control operation to the middle layer is carried out. Send the operation signal S23. The middle layer that has received this signal transmits the operation signal S13 to the lower layer regardless of whether the activation condition is met or not. The lower layer that has received this signal operates at the highest speed of the inverter regardless of whether the activation condition is established or not, and sends the operation signal S12 to the middle layer. The middle layer that receives this signal runs at the inverter's highest speed.

As described above, according to the implementation of this example, when water is concentrated in a part of the area or in a local area in a short period of time, the linked operation can be performed, and the coordination of the whole system can be prevented. Problems such as a drop in water supply pressure occur. Furthermore, it is thereby possible to prevent the oscillation phenomenon of starting and stopping in each of the systems for the low floors, the middle floors, and the high floors.

[Example 3]

Hereinafter, Embodiment 3 of the present invention will be described using the drawings. 2 to 7 are the same as those in Embodiment 1, and thus description thereof will be omitted here.

Fig. 8 shows a system diagram of a pressurized water supply system for middle and high-rise buildings of this embodiment. 1 is a water supply pipe for tap water, and 4 is for connecting the suction side with the water supply pipe for tap water through the water supply pipe branch pipe 2 and the water meter 3, and then passing through the water supply pipe 5 to feed water to the lower-level area needs (such as faucets 5a, 5b, 5c) The lower zone uses a pressurized water supply system, and 6 is to connect the suction side with the water supply pipe 5 of the above-mentioned low zone pressurized water supply system, through the water supply pipe 7, to the middle layer of the middle zone that needs to be fed (such as faucets 7a, 7b, 7c) District pressurized water supply system, 8 is to connect the suction side with the water delivery pipe 8 of the above-mentioned middle-level district pressurized water supply system, through the water supply pipe 10, to the high-rise area where the high-rise area needs water (such as faucets 10a, 10b, 10c) Use pressurized water supply system.

The pressure resistance of the pressurized water supply system for the middle layer area considers the discharge pressure head of the pressurized water supply system for the low layer area and the pressure head generated by itself, and the pressure resistance of the pressurized water supply system for the high layer area considers the discharge of the pressurized water supply system for the middle layer area Pressure head vs. self-occurring pressure head. That is, the pressure-resistant use of bushings and shaft seal members of booster pumps for middle and upper floors has been improved as a countermeasure. On the basis of carrying out such countermeasures, in the present embodiment, each of these pressurized water supply systems for the low-rise area, the middle-rise area, and the high-rise area is arranged on the same floor of the low-rise area.

For example, when a booster water supply system is installed in a building for the mid-rise area or high-rise area, not only the installation space of the booster pump but also the space for its control panel must be considered. In this case, it is basically necessary to prepare a room called a machine room, but it is preferable to save more space. It is also considered that depending on the installation situation of the building, it is often difficult to install a pressurized water supply system because there is no such space. Furthermore, since installation of such a machine room requires equipment costs, it is preferable to combine the machine rooms into one from the viewpoint of cost reduction.

Therefore, in this embodiment, space saving can be realized by arranging the pressurized water supply systems for the middle zone and the high zone respectively on the same floor as the low zone, as described above. Furthermore, it is possible to provide a low-cost system by reducing the equipment cost and management cost of the machine room.

As explained above, according to this embodiment, because the low-rise area, the middle-level area and the high-level area are set on the same floor of the low-level area with the pressurized water supply system, or the low-level area and the middle-level area are set on the same floor with the pressurized water supply system On the same floor of the low-rise area, the pressurized water supply system for the high-rise area is installed on the floor of the middle area, so the problem of installation space or high equipment cost is eliminated. Since it is installed on the same floor, it is easy to carry out wiring work such as cables for signal transmission and reception between the pressurized water supply systems.

[Example 4]

Hereinafter, Embodiment 4 of the present invention will be described using FIG. 9 .

Fig. 9 shows a system diagram of a pressurized water supply system for middle and high-rise buildings in this embodiment. 1 is a water supply pipe for tap water, and 4 is for connecting the suction side with the water supply pipe for tap water through the water supply pipe branch pipe 2 and the water meter 3, and then passing through the water supply pipe 5 to feed water to the lower-level area needs (such as faucets 5a, 5b, 5c) The lower zone uses a pressurized water supply system, and 6 is to connect the suction side with the water supply pipe 5 of the above-mentioned low zone pressurized water supply system, through the water supply pipe 7, to the middle layer of the middle zone that needs to be fed (such as faucets 7a, 7b, 7c) District pressurized water supply system, 8 is to connect the suction side with the water delivery pipe 8 of the above-mentioned middle-level district pressurized water supply system, through the water supply pipe 9, to the high-rise area where the high-rise area needs water (such as faucets 9a, 9b, 9c) Use pressurized water supply system.

Here, in this embodiment, space saving is achieved by arranging the pressurized water supply systems of the lower and middle floors on the same floor of the lower floor. Or, since there is no space in the middle-rise area in the building, but there is a space for installation in the lower floors, it is possible to cope with such a case. In the case of installation on the same floor as in Example 1, since the discharge pressure head of the pressurized water supply system for the lower floor area is directly applied, this point must be taken into consideration.

In Embodiment 1, the pressurized water supply systems of the low, middle and high floors are all arranged on the same floor of the low floor area, but the load of the pressurized water supply systems of the high floors increases. Therefore, in this embodiment, the withstand pressure of the pressurized water supply system for the middle zone considers the discharge pressure head and the self-generated pressure head of the pressurized water supply system for the low zone, and the pressurized water supply system for the high zone does not consider the withstand pressure. Accordingly, the problem of withstand voltage can be eliminated while achieving space saving and low cost.

In addition, in this case, the pressure resistance of the bushing, the shaft seal member, etc. of the booster pump for the middle stage is improved as a measure and used. On the basis of this countermeasure, the pressurized water supply systems for the low-rise area and the middle-level area are set on the same floor of the low-rise area, and the pressurized water supply system for the high-rise area is set on the same floor as the pressurized water supply system for the middle-level area. The discharge pressure head of the system is on the mezzanine zone floor.

[Example 5]

Hereinafter, Embodiment 5 of the present invention will be described using the drawings. 2 to 7 are the same as those in Embodiment 1, and thus description thereof will be omitted here.

Fig. 10 shows a system diagram of a pressurized water supply system for middle and high-rise buildings in this embodiment. 1 is a water supply pipe for tap water, and 4 is for connecting the suction side with the water supply pipe for tap water through the water supply pipe branch pipe 2 and the water meter 3, and then passing through the water supply pipe 5 to feed water to the lower-level area needs (such as faucets 5a, 5b, 5c) The lower zone uses a pressurized water supply system, and 6 is to connect the suction side with the water supply pipe 5 of the above-mentioned low zone pressurized water supply system, through the water supply pipe 7, to the middle layer of the middle zone that needs to be fed (such as faucets 7a, 7b, 7c) District pressurized water supply system, 8 is to directly connect the suction side with the water delivery pipe 7 of the above-mentioned middle-level district pressurized water supply system, through the water supply pipe 9, to the high-level high-rise area that requires end (such as water taps 9a, 9b, 9c) water supply District pressurized water supply system.

The operation signal S11 and its response signal S12 indicating the operating state of the pressurized water supply system for the low-level area and its response signal S12, and the operation signal S13 and its response signal for indicating the operating state of the pressurized water supply system for the middle-level area are connected between the low-level and middle-level areas. Response signal S14. In addition, the operation signal S21 indicating the operating state of the pressurized water supply system for the middle area and its response signal S22, and the operation signal S23 indicating the operating state of the pressurized water supply system for the high-level area are connected between the pressurized water supply system for the middle floor and the high-rise area. And its response signal S24. Furthermore, the connection between the pressurized water supply system for the low-level and middle-level areas indicates that the fault signal K11 and its response signal K12 of the abnormal state of the pressurized water supply system for the low-level area, and the connection between the pressurized water supply systems for the middle and high-level areas indicate the middle-level area. The fault signal K13 and the response signal K14 of the abnormal state of the pressurized water supply system. Here, an abnormal state of the system will be described.

For example, when the pressurized water supply systems in each of the low-rise area, middle-rise area, and high-rise area work independently, if there is a construction water failure on the side of the water supply pipe for tap water, the protection function will be activated, and the pressurized water supply system will be activated. not able to function. Since such a protection function is only set on the side of the lower floor area, the protection measures for the pressurized water supply system set in the upper area are slow, and idling may occur. If idling occurs, there is a possibility of machine damage.

In addition, as an additional function of the pressurized water supply system installed in the lower floor area, there is a function to stop the booster pump and perform bypass water supply (main pressure water supply) when the side pressure of the water supply pipe for tap water is high. If only this function is activated, there is a possibility that the water pressure in the upper part of the lower layer area will be insufficient, and the pressurized water supply system may not be able to operate, resulting in the possibility of water cut-off in the future. Furthermore, when all the booster pumps of the pressurized water supply system installed below the uppermost layer area fail, the protection measures for the upper layer area will be delayed, resulting in the possibility of equipment damage.

In the abnormal state signal K11, there is a drop in inflow pressure on the side of the water supply pipe for tap water, a high inflow pressure, and a booster pump of the booster water supply system for the lower floor area, an earth leakage circuit breaker, a variable speed drive unit (such as an inverter), etc. Abnormal signal when equipment fails. Similarly, in the abnormal signal K13, the abnormal signal when all equipment such as the booster pump, the earth leakage circuit breaker, and the variable speed drive unit (such as an inverter) of the above-mentioned booster water supply system for the middle layer area is faulty is carried. In this embodiment, these signals are sent and received mutually to realize a linked operation system. In addition, these signals may use a communication line or may be wireless.

A specific implementation of the system configured as above in this embodiment will be described. As mentioned above, the operation, stop and abnormal state signals are sent and received between the pressurized water supply systems, that is, between the lower layer and the middle layer, the operation signal S11 is sent from the lower layer to the middle layer, and the response signal S12 is received, and the signal is transmitted from the middle layer to the lower layer. The operation signal S13 is transmitted, the response signal S14 is received, and signals are transmitted and received mutually. Furthermore, an abnormal state signal K11 indicating an emergency is sent from the pressurized water supply system for the lower floor area to the pressurized water supply system for the middle floor area, and a response signal K12 thereof is received. Send an abnormal state signal K12 representing an emergency state from the pressurized water supply system in the middle layer area to the pressurized water supply system in the high layer area, and receive its response signal K13.

When the inflow pressure drops on the side of the water supply pipe for tap water, if the pressurized water supply system for the lower area is running, it will stop. The system will stop if it is running when receiving this signal, and at the same time, send an abnormal state signal K13 to the pressurized water supply system for high-rise areas, and the pressurized water supply system for high-rise areas will stop if it is running when receiving the emergency signal. In this way, protection coordination is obtained and linkage operation is performed.

As a result, when an abnormality occurs in the lower layer area, the operation is stopped promptly in the upper layer area as well, so it is possible to prevent equipment damage caused by idling when protective measures for the upper layer area are delayed.

In addition, in other implementations of this embodiment, the procedure at the time of recovery (transitioning the state to the operable state) is added to the above-mentioned embodiment. That is, an abnormal state signal K11 indicating an emergency is sent from the pressurized water supply system for the lower floor area to the pressurized water supply system for the middle floor area, and a response signal K12 thereof is received. Send an abnormal state signal K12 representing an emergency state from the pressurized water supply system in the middle layer area to the pressurized water supply system in the high layer area, and receive its response signal K13.

Moreover, when the inflow pressure drop occurs on the side of the water supply pipe for tap water, if the pressurized water supply system for the lower floor area is running, it will stop, and at the same time, an abnormal state signal K11 will be sent to the pressurized water supply system for the middle floor area, and the pressurized water supply system for the middle floor area will be used. The pressurized water supply system will stop if it is running when receiving this signal, and at the same time, send an abnormal state signal K13 to the pressurized water supply system for the high-rise area. If the pressurized water supply system for the high-rise area is in operation when receiving the emergency signal stop.

As the recovery sequence in the above-mentioned present embodiment, when the drop in the inflow pressure of the water supply pipe for the above-mentioned tap water is recovered, the pressurized water supply system for the lower layer area shifts the state from the stopped state to the operational state, and at the same time, transfers the pressure to the middle layer. The pressurized water supply system for the district sends a signal to release the emergency state. When the pressurized water supply system for the middle floor receives the signal, the state is transferred from the stop state to the operational state. When the pressurized water supply system for the high-rise area receives the emergency state release signal, the state will be transferred from the stop state to the operable state. In this way, protection coordination is obtained and linkage operation is performed. As a result, since the operation starts from the lower zone, it is possible to prevent the situation where the water pressure in the upper zone is insufficient and the pressurized water supply system fails to operate and the water is cut off.

Furthermore, in another embodiment of this embodiment, the procedure at the time of recovery (transition of the state to operation when the operation was in operation before the emergency stop) is added to the above-mentioned embodiment. Similarly, an abnormal state signal K11 indicating an emergency is sent from the pressurized water supply system for the lower layer to the pressurized water supply system for the middle layer, and the response signal K12 is received. Send an abnormal state signal K12 representing an emergency state from the pressurized water supply system in the middle layer area to the pressurized water supply system in the high layer area, and receive its response signal K13.

Moreover, when the inflow pressure drop occurs on the side of the water supply pipe for tap water, if the pressurized water supply system for the lower floor area is running, it will stop, and at the same time, an abnormal state signal K11 will be sent to the pressurized water supply system for the middle floor area, and the pressurized water supply system for the middle floor area will be used. The pressurized water supply system will stop if it is running when receiving this signal, and at the same time, send an abnormal state signal K13 to the pressurized water supply system for the high-rise area. If the pressurized water supply system for the high-rise area is in operation when receiving the emergency signal stop.

Furthermore, in this embodiment, when the drop in inflow pressure on the water supply pipe side for tap water has been recovered, if the pressurized water supply system for the low-rise area was operating before the emergency stop, the pressurized water supply system for the middle-level area will be pumped to the mid-level area at the same time as the operation is started. The pressurized water supply system sends a signal to release the emergency state. When the pressurized water supply system for the middle layer area receives this signal, if it is running before the emergency stop, it will send an emergency state to the pressurized water supply system for the high-rise area at the same time as it starts to operate. When the pressurized water supply system for high-rise areas receives the release signal of the emergency state, if it was running before the emergency stop, it will start to run. In this way, protection coordination is obtained and linkage operation is performed. By considering the operation state before the emergency stop in this way, it is possible to prevent the above-mentioned equipment damage due to idling or water cutoff due to lack of upper water pressure.

Furthermore, alarm display and alarm transmission are performed in other embodiments of this embodiment. That is, an abnormal state signal K11 indicating an emergency is sent from the pressurized water supply system for the lower floor area to the pressurized water supply system for the middle floor area, and a response signal K12 thereof is received. Send an abnormal state signal K13 representing an emergency state from the pressurized water supply system in the middle layer area to the pressurized water supply system in the high layer area, and receive its response signal K14. In the case of a drop in inflow pressure on the side of the water supply pipe for tap water, the pressurized water supply system for the lower layer will be used to display or send an alarm. At the same time, an abnormal state signal will be sent to the pressurized water supply system for the middle layer. When the signal is received, an alarm display or alarm is sent, and at the same time, an emergency signal is sent to the pressurized water supply system for the high-rise area. When the pressurized water supply system for the high-rise area receives the emergency signal, an alarm display or alarm is performed. send. In this way, protection coordination is obtained and linkage operation is performed.

Furthermore, in another embodiment of the present embodiment, the configuration method of the pressurized water supply system of the lower and middle floors and the situation when an abnormal state until the water cutoff occurs in the system below the highest level are shown. The pressurized water supply system other than the pressurized water supply system for the uppermost area uses a booster pump as a pump that can supply 100% of the water supply capacity to the area. The double system consists of a check valve and a water control valve. Set from The signal sending units for sending abnormal state signals K11 and K13 respectively from the pressurized water supply system for the low-level area to the pressurized water supply system for the middle-level area, and from the pressurized water supply system for the middle-level area to the pressurized water supply system for the high-level area. In the case that both booster pumps of the pressurized water supply system fail and stop, an abnormal state signal K11 is sent from the pressurized water supply system for the lower layer area to the pressurized water supply system for the middle layer area, and the pressurized water supply system for the middle layer area is activated. Stop running when receiving this signal, and send an abnormal state signal K13 to the pressurized water supply system for high-rise areas at the same time, and stop running when the pressurized water supply system for high-rise areas receives the emergency state signal. In this way, protection coordination is obtained and linkage operation is performed.

Furthermore, according to another embodiment of this embodiment, the state of the middle layer and the upper layer when the inflow pressure rises and the lower layer stops. Send and receive operation, stop and abnormal state signals between the pressurized water supply systems, that is, between the lower layer and the middle layer, send the operation signal S11 from the lower layer to the middle layer, receive the response signal S12, and send the operation signal S13 from the middle layer to the lower layer , receive the response signal S14, and send and receive signals with each other. Furthermore, an abnormal state signal K11 indicating an emergency is sent from the pressurized water supply system for the lower floor area to the pressurized water supply system for the middle floor area, and a response signal K12 thereof is received. Send an abnormal state signal K12 representing an emergency state from the pressurized water supply system in the middle layer area to the pressurized water supply system in the high layer area, and receive its response signal K13.

When the inflow pressure rises on the side of the water supply pipe for tap water, if the pressurized water supply system for the lower area is operating, it will continue to operate, and at the same time, an abnormal state signal K11 (indicating that the water supply system for tap water) is sent to the pressurized water supply system for the middle area The meaning of the rise of the inflow pressure on the pipe side), the pressurized water supply system for the middle layer area will continue to operate if it is running when it receives this signal, and at the same time, send an abnormal state signal K13 to the pressurized water supply system for the high-level area (indicating that the water supply system for tap water The meaning of the rise of the inflow pressure on the pipe side), the pressurized water supply system for the high-rise area will stop if it is running when it receives the emergency signal, so as to obtain protection coordination and carry out linked operation.

Furthermore, according to another embodiment of this embodiment, other situations of the middle layer and the upper layer when the inflow pressure increases and the lower layer stops in this embodiment are shown.

That is, the operation, stop and abnormal state signals are sent and received between the pressurized water supply systems, that is, between the lower layer and the middle layer, the operation signal S11 is sent from the lower layer to the middle layer, and the response signal S12 is received, and the operation signal is sent from the middle layer to the lower layer. The signal S13 receives its response signal S14, and mutually transmits and receives signals. Furthermore, an abnormal state signal K11 indicating an emergency is sent from the pressurized water supply system for the lower floor area to the pressurized water supply system for the middle floor area, and a response signal K12 thereof is received. Send an abnormal state signal K12 representing an emergency state from the pressurized water supply system in the middle layer area to the pressurized water supply system in the high layer area, and receive its response signal K13.

When the inflow pressure rises on the side of the water supply pipe for tap water, when there is no water in the layer above the lower layer and only the booster system for the lower layer is operating, stop the booster pump for the lower layer. Perform bypass feed water.

As explained above, according to this embodiment, as a function added to the pressurized water supply system installed in the lower floor area, when the pressure on the side of the water supply pipe for tap water is high, the booster pump is stopped to perform bypass water supply (main pressure water supply). Prevent due to the action of this function, the water pressure in the layer above the lower layer area is insufficient, the pressurized water supply system cannot operate, and thereafter, the water will be cut off. Furthermore, when all the booster pumps of the pressurized water supply system installed below the uppermost layer area fail, the protection measures for the upper layer area are delayed, and there is a possibility of equipment damage. In addition, it can eliminate the protection of the pressurized water supply system at the upper level of the middle zone when the inflow pressure drops, and the protection of the pressurized water supply system set at the upper zone when all the booster pumps of the boosted water supply system set at the lower zone fail, and When bypassing water supply, the problem of protection of the pressurized water supply system installed in the upper part of the middle layer area, and at the same time achieve protection coordination in each area, a stable and highly reliable linkage operation system.

In addition, parameters necessary for these controls are stored in a memory, for example, as shown in FIGS. 11 and 12 .

FIG. 4 shows a circuit diagram of control boards CU1 to CU2.

PW is a power supply, and INV1 and INV2 are variable-speed drive devices for driving No. 1 and No. 2 booster pumps, such as inverters. This inverter is started and stopped based on operation command signals STX1 and STX2, and frequency controlled based on frequency command signals fx1 and fx2. Variable frequency and variable voltage are supplied to the No. 1 and No. 2 booster pump motors IM1 and IM1. CONS1 and CONS2 are the operators respectively, setting parameters such as the acceleration time of the inverter or over-current tripping level, layer area parameters (for example, the upper layer is 0, the middle layer is 1, and the lower layer is 2), and the water consumption of the upper layer is determined. How many parameters of the amount, or a separate command to stop and so on.

ELB1 and ELB2 are earth-leakage circuit breakers that perform earth-leakage protection for inverters and motors installed behind them. CU is a control device, which is composed of microprocessor CPU, input and output ports PIO-1~PIQ-5, analog input and output ports D/A, memory M, and regulated power supply circuit AVR. In addition, programs necessary for the operation of the pressurized water supply system are stored in the above-mentioned memory M. SS is a stop switch, and when it is ON, power is supplied to CU through AVR. Cut off the power when OFF, and stop if running. Z is the relay drive unit, through the software processing of the CPU, the ON and OFF signals are output from PIO-4 to Z, and the relays STX1, STX2, X1 and X2 are opened and closed. Relays STX1 and STX2 (the output) are the driving stop signals of the above-mentioned inverter. In other pressurized water supply system control boards, the relay X1 (the output) is used as the operation signal, and the relay X2 (the output) is output as the response signal. . In the case of the middle layer area, since it is transmitted to the lower layer and the upper layer, two signals are required. Other than that, only 1 signal is OK. In addition, the reception of the operation signal S11 (or) and the response signal S12 (or) from other pressurized water supply system control boards is received by relays X3 and X4, and these signals are input from PIO-5. As described above, the control system is the same for each area, and standardization is pursued.

In addition, SW is a switch for setting the control parameters of the pressurized water supply system shown in FIGS. 5 to 7 . Their values are fetched from PIO-3 and stored in the storage unit (memory). The above-mentioned pressure sensor for detecting the pressure head on the water supply pipe side of the water channel and the pressure sensor for detecting the pressure head on the discharge side are taken in by the analog port A/D and stored in the memory for processing (for example, converted into 0 to 100m). Details of these parameters are shown in Figures 11 and 12.

5 is an operation characteristic diagram showing the operation control and parameters of the pressurized water supply system installed in the lower floor area, the left side shows the suction side, and the right side shows the discharge side. The suction side is the pressure head of the water supply pipe for tap water, SLL is the pressure head used to stop the pump when the pressure head of the water supply pipe drops, and SL is the recovery pressure head. A normal setting example is 7m, and recovery is 10m. That is, use the pressure sensor PS11 to detect the pressure on the inflow side. If the value drops below the above-mentioned parameter SLL for a certain period of time, it has nothing to do with the use of water, and the pressurized water supply system will be stopped. If the detected inflow pressure is as high as SL If it is above and lasts for a certain period of time, the system will recover. This is called the inflow pressure drop stop function, and it is an emergency response function when water supply cannot be supplied due to construction interruptions on the water supply pipe side.

The parameter SHH is a parameter that the pressure head of the water supply pipe is sufficiently high, and the booster pump is not operated, and only the water supply pipe is used to pressurize the water supply, and SH is the recovery pressure head. The usual setting is to set SHH to the specified pressure H0 on the right discharge side or slightly higher. SH is set several meters lower than SHH. That is, use the pressure sensor PS12 to detect the pressure on the inflow side. If the value rises above the above parameter SHH and lasts for a certain period of time, it has nothing to do with the use of water. Water is supplied by the pressure of the water channel drain pipe, and if the detected inflow pressure drops below SH and lasts for a certain period of time, the system will recover. This is called the inflow pressure rise stop function.

In this embodiment, the pressurized water supply system set in each of the low-rise area, the middle-level area and the high-rise area uses the same hardware structure regardless of the mechanical system or the control system.

These parameters are stored in the above-mentioned storage unit. When the above-mentioned layer area parameters are written, it means that the middle layer area and the high-level area are used, and the function of stopping the inflow pressure drop is disabled, and the inflow pressure drop and recovery parameters are written. Software processing into data for idling protection.

As explained above, according to the present invention, the pressurized water supply system provided in each of the low-rise area, the middle-level area, and the high-level area uses almost the same device regardless of the mechanical system or the hardware structure of the control system. By utilizing the functions of the low-rise area, middle-rise area, and high-rise area, it is possible to standardize and improve productivity. In addition, these systems can be popularized thereby.

Figure 13 shows the full head of the booster pump, as shown by the hydraulic gradient line, the water supply system is realized according to the gradual decrease of the above pressure loss, so that the pressure head P5 required for water supply at the highest tap can be obtained.

Fig. 2 is an internal structure diagram of a pressurized water supply system 4 arranged in a low-rise area of a building. CU1 is the control device of the pressurized water supply system 4, and transmits and receives the above-mentioned signals S11-S14, and operates/stops the pressurized water supply system 4 in the area according to the reception of these signals. BP11 and BP12 are No. 1 and No. 2 booster pumps, respectively, and power cables S34 and S35 are passed between them, and are alternately operated and stopped by the above-mentioned control unit CU1.

11 is a one-way valve, which prevents the return flow of the pressurized water supply system 4 to the outlet side, and seeks to prevent pollution. Reference numeral 15 denotes a bypass pipe provided with a check valve 14 on the way, and is arranged side by side on the booster pumps BP11 and BP12. When these pumps were in operation, the check valve 14 prevented circulation from the discharge side to the water supply pipe 2 side for tap water. Water is supplied via bypass pipe 15 . 10-1～10-6 are water control valves, and 12 and 13 are check valves. The above-mentioned booster pumps BP11 and BP12 and their associated components are installed on the water supply pipe in-line, and the details will be described later.

Fig. 3 is an internal structure diagram of pressurized water supply systems 6 and 8 arranged in the middle and high-rise areas of the building. CU2 and CU3 are the control devices of pressurized water supply systems 6 and 8 respectively. Signals S11 to S14 are transmitted and received between control devices CU1 and CU2, and signals S21 to S24 are transmitted and received between control devices CU2 and CU3. And, upon receiving any one of the above-mentioned signals, the control devices CU2 and CU3 respectively perform operation and stop control of the pressurized water supply system 6 and the pressurized water supply system 8 in the area.

BP21 and BP22 are No. 1 and No. 2 booster pumps respectively. They are the same as those shown in Fig. 2. They are wired with power cables S34 and S35 to form an alternate operation structure. PS21 is a pressure sensor for detecting a pressure head on the side of the water channel arrangement pipe, and sends an electric signal S30 corresponding to the detected pressure head here to the control unit CU2 (CU3). Similarly, PS22 is a pressure sensor that detects the discharge pressure head (water supply pressure head), and sends an electrical signal S31 corresponding to the detected pressure head to the control unit CP2 (CU3).

FS21 and FS22 are respectively installed on the discharge side of No. 1 and No. 2 booster pumps to detect the state of too little water consumption, and send electrical signals S32 and S33 to the control unit CU2 (CU3). T2 (T3) is a pressure tank that retains air inside and is used for the purpose of preventing pressure fluctuations and accumulating pressure. In addition, 10-3 to 10-6 are water control valves, and 12 and 13 are check valves. The above-mentioned booster pumps BP21 and BP22 and their related components are arranged in-line on the water supply pipe, and the details will be described later.

In Fig. 3, the one-way valve 11 (also including the water control valves 10-1, 10-2 before and after them) and the bypass pipe 15 arranged in the pressurized water supply system 4 (Fig. 2) of the above-mentioned low-rise area are omitted. (including check valve 14). This is because the pressure of the water delivery pipe 5 (or 7 ) on the suction side is not fed by the operation of the booster pumps BP21 and BP22 in the middle and upper floors. Like this, by saving check valve 11 or bypass pipe 15, seek to reduce equipment cost, at the same time, because do not need to consider the resistance of check valve 11 (also including the water control valve 10-1, 10-2 before and after them), The pump performance (pressure head) of the selected booster pumps BP21 and BP22 can thus be reduced accordingly.

The SW is a setting unit (switch) for setting in advance control parameters represented by the pump performance curves of the lower, middle, and upper levels shown in FIGS. 5 to 7 described later. These control parameters are fetched from PIO-3 and stored in memory M. Specifically, in the memory of the control unit CU1 of the lower layer, control parameters for the operation of the lower layer shown in FIG. In the memory of the control unit CU2 of the middle stage, control parameters for the operation of the middle stage shown in FIG. In the memory of the control unit CU3 for the high-rise area, the control parameters for the operation of the high-rise area shown in FIG. 7 , the instantaneous maximum water volume Q3 of the pump performance, and the required head TH3 for the high-rise area are stored in advance.

Furthermore, in the control device of each floor area, the relationship between the control parameters of the operation of each floor area, the instantaneous maximum water volume and the necessary head is stored. That is, after each pressurized water supply system is installed in the building, if the instantaneous maximum water volume (Q1+Q2+Q3) or the necessary head TH1 is set by the setting unit SW, then the set control device reads The control parameters are used to execute the operation for the lower layer. Similarly, if the instantaneous maximum water volume (Q2+Q3) or the necessary head TH2 is set, the set control device reads the control parameters of the middle layer area and performs the operation for the middle layer. If the instantaneous maximum water volume (Q3) is set Or the necessary head TH3, the control device that has been set reads out the control parameters of the high-rise area, and executes the operation for the high-rise.

Here, as the instantaneous maximum water volume of this layer area, including the instantaneous maximum water volume of its high-level layer area, it is because in the case of multiple layer areas operating in series, the water volume required to supply its high-level layer area is also required in this layer area. Furthermore, the signals of the above-mentioned pressure sensor for detecting the pressure head on the side of the water channel arrangement pipe and the pressure sensor for detecting the pressure head on the discharge side are taken in from the analog port A/D, and stored in the memory M (for example, converted into 0 to 100m) .

In addition, in FIG. 4, the relay driver Z, relays STX1, STX2, X1-X4 are shown outside the control unit CU, but they may be included in the control unit CU.

Furthermore, in the above, the so-called high-level zone is relatively high and low. For example, as shown in Figure 1, in the case of a low-rise zone, a middle-rise zone, and a high-rise zone in a building, the middle-level zone becomes a high-level zone for the low-rise zone, and the high-level zone The zone becomes the high-level zone for the mesosphere zone.

FIG. 5( b ) shows a pump performance curve showing the operation of the booster pump and parameters related thereto. The vertical axis represents the total head, and the horizontal axis represents the discharge amount Q (Q0 corresponds to the maximum water consumption).

Curve A is the Q-H performance curve of the pump when the pump is running at the inverter frequency fmax (100% frequency). Curve F is the load curve including the resistance of the pump itself or the water supply pipe when the booster pump is operated at a variable speed through the operation of the pressurized water supply system 4 in the lower floor area to supply water to this area. In addition, the desired water quantity for supplying water to this region is the above-mentioned discharge quantity (maximum water quantity) Q0, and the desired pressure head is the full head H0. The Q0 and H0 are design values, and they are preferably designed to be on the intersection point O of the above-mentioned pump Q-H performance curve A and the resistance curve F, but may also be designed to be smaller than the intersection point O on the resistance curve F.

Here, corresponding to the low-rise area, the above-mentioned Q0 is Q0=Q1+Q2+Q3 as the instantaneous maximum water volume, and H0 is set as H0=TH1 as the total head, and is set in the memory M of the control unit CU1.

Curves B and C are the Q-H performance curves of the pump when the inverter frequency is changed to f1, fmin (lowest frequency) and the pump is operated, respectively. The frequency of the inverter is stepless, and the corresponding curve can be drawn between the curve A and the curve C. For the convenience of explanation, curves B and C are used as representatives. In addition, it means that when the inverter frequency f1 is running, the Q-H performance curve of the pump is B, and the pump discharge is Q1. When the inverter frequency fmin is running, the Q-H performance curve of the pump is C, and the pump discharge is 0.

Moreover, when the water consumption varies from 0 to Q0, the booster pump will follow the resistance curve F and estimate the pressure head according to the frequency fmin to fmax output from the inverter, and perform operation control in a manner called constant end pressure control. When controlling, use the curve F as the target pressure. When the discharge volume is 0, set the desired value to H00 (corresponding to the inverter frequency fmin), and set the desired value to the discharge volume Qmax. It is H0 (corresponding to inverter frequency fmax). In addition, linear approximation is performed between H00 and H0 of the curve F and treated as a function or as a table.

6 is an operation characteristic diagram showing parameters for controlling the operation of the pressurized water supply system BU2 installed in the middle floor of the building, (a) showing the suction side of the pump, and (b) showing the discharge side of the pump. In (a), SHH and SH shown in Fig. 5(a) are omitted, and (b) is the same as Fig. 5(b), but the design values Q0 and H0 are values necessary for water supply to the middle zone.

Here, corresponding to the middle zone, the above-mentioned Q0 is set as Q0=Q2+Q3 as the instantaneous maximum water volume, and H0 is set as H0=TH2 as the total lift, which is set in the memory M of the control unit CU1.

7 is an operation characteristic diagram showing parameters for controlling the operation of the pressurized water supply system BU3 installed in a high-rise area of a building, (a) showing the suction side, and (b) showing the discharge side. (a) Same as FIG. 6(a), (b) The horizontal line G at the time of constant discharge pressure control which is unnecessary in the uppermost layer region of the building is omitted from FIG. 6(b). That is, in high-rise areas, since the pump operates along the resistance curve F, the horizontal line G is not required. The design values Q0 and H0 are values required for water supply in the high-rise area.

Here, corresponding to the high-rise area, the above-mentioned Q0 is set as Q0=Q3 as the instantaneous maximum water volume, and H0 is set as H0=TH3 as the total head, and is set in the memory M of the control unit CU1.

In FIGS. 5 to 7 , PON is the starting pressure head of the booster pump (generally set close to H00), and POFF is the stop pressure head of the booster pump (generally set higher than PON). Qmin is the discharge amount for stopping the booster pump when the water consumption is too low, and is detected by the above-mentioned flow detection means. Furthermore, this state is detected, and the frequency of the inverter is raised to foff, and the booster pump is operated and then stopped in order to accumulate pressure in the pressure tank immediately before stopping. At this time, the booster pump runs along the pump Q-H characteristic curve D, and stops if the stop pressure head reaches POFF. In addition, the above-mentioned control on the suction side is performed based on the detection of the pressure sensor PS11 (PS21), and the pressure control on the discharge side is performed based on the detection of the pressure sensor PS12 (PS22).

Fig. 14 is an explanatory diagram for calculating the front lift. When the discharge pressure head (equivalent to the full discharge head) of the (lower or lower) floor area is recorded as Pout, (a) represents the installation position ratio of the pressurized water supply system in the upper (higher) layer area of the above-mentioned layer area In the case that the highest tap in this layer is high, the Pout (actual head of the discharge side) at this time is taken as the height difference between the pressurized water supply system BU in the above-mentioned upper layer area and the pressurized water supply system in this layer area.

In addition, (b) indicates that the setting position of the pressurized water supply system of the upper floor area of the above-mentioned floor area is lower than the highest water tap of the above-mentioned floor area, and the actual head of the discharge side is used as the pressurized water supply system of the above-mentioned floor area The height difference from the highest faucet above. In a word, the pressurized water supply system of the above-mentioned layer area is equipped with a booster pump capable of ensuring the pressure head of the suction side of the pressurized water supply system of the above-mentioned upper layer area to be about 10m, which meets the required pressure head pump performance, and realizes the Pressurized water supply system for high-rise buildings.

Figure 14(a) and (b) In other words, compare the setting position of the pressurized water supply system in the upper layer area of this layer area with the setting position of the highest water tap in this layer area, and set a certain high position (Also including the case of the same height) The height difference from the pressurized water supply system in this layer area is used as the actual head of the discharge side.
