Abstract
The utility model discloses a vertical self-sucking pump, on the basis of original structure with a motor, a coupling, a vertical pump shaft, a supporting seat, a pump cover, a pump body, two bearings positioned on a pump shaft, a sealing device and a vane wheel, a liquid storage chamber with a suction conical tube is arranged inside the pump body, the vane wheel is placed in the suction conical tube, the liquid inlet of the pump body is connected with the liquid storage chamber, an electrical air control valve linked with the motor is arranged on a liquid feeder tube, a liquid outlet tube is connected with the suction conical tube, a single direction check valve is positioned in the liquid outlet tube. With the advantages of best integration, reliable and stable self suction, the utility model integrates the pump body, gas and water separation chamber and liquid storage chamber in one body and realized the function of ''once guiding, perpetual self suction'', therefore the utility model is suitable for polluted water environment; passing through arranging the auxiliary vanes on pump shaft over pump cover, the utility model form dynamic hermetization and can stop liquid of liquid storage chamber entering stuffing box, guarantee sealed reliability and prolong the service life of pump.
Description
Technical field
The utility model relates to a kind of self-priming pump.
Background technique
The precondition of self-priming pump proper functioning is that impeller is immersed in the liquid, so, must bottom valve be installed in the suction line end of pump, prestart should be irritated liquid earlier in the pump housing, gas in the pipeline drained make liquid-immersed impeller, and make full of liquid in the pipeline, pump can proper functioning.For solving the inconvenience that pump exists in use, vacuum pump had been installed in self-priming pump afterwards, in bearing housing, increase shifting fork mechanism simultaneously, during pump startup, vacuum pump work drains air in the pipeline, makes pump startup and proper functioning, utilize shifting fork mechanism that vacuum pump is quit work again, this pump structure complexity need be used the handling shifting fork mechanism during pump work, is difficult to realize the automation that moves, can't reach the function of " drainage, lifelong self-priming "; Simultaneously, existing sealing configuration is for to be provided with packing seal, during pump work on the pump shaft above the pump cover, liquid in the pipeline is in high pressure conditions, easily passes pump cover and scurries in the Stuffing box, the poor reliability of sealing, impurity wherein can be accelerated the wearing and tearing of seal arrangement, shortens the working life of pump.
The model utility content
The purpose of this utility model is the above-mentioned defective that exists at prior art, provides a kind of and has " drainage, lifelong self-priming " function, the good reliability of sealing, the self-priming pump of long service life.
For achieving the above object, vertical self-sucking pump of the present utility model, comprise motor, coupling, vertical pump shaft, bearing, pump cover, the pump housing that has liquid inlet pipe, drain pipe and liquid filling hole and be connected with bearing, and be installed on two bearings, seal arrangement and impeller etc. on the pump shaft, (during electric motor starting, electric air control valve is closed to be provided with electric air control valve with motor linkage on liquid inlet pipe; When motor stops, electric air control valve is opened), in drain pipe, be provided with one way stop peturn valve, it is characterized in that the suction Taper Pipe that this pump housing also has liquid storage room, communicates with liquid storage room, impeller places and sucks in the Taper Pipe, and liquid inlet pipe communicates with liquid storage room, and drain pipe communicates with the suction Taper Pipe, the mouth of pipe of liquid inlet pipe and drain pipe all is higher than the peak of impeller, and the position of electric air control valve is higher than the peak of liquid storage room;
Working procedure of the present utility model is: prestart is irritated liquid by liquid filling hole in liquid storage room, close liquid filling hole after filling with, motor is started working, electric air control valve is a closed condition simultaneously, carbonated drink is separated in the pump housing and finishes, form self-priming performance, when the gas in the liquid inlet pipe drained, pump began proper functioning; When motor stops, electric air control valve is opened simultaneously, liquid inlet pipe is communicated with atmosphere, avoided because of the effect of siphon the liquid in the liquid inlet pipe all being exhausted, simultaneously, one way stop peturn valve is a closed condition, guarantee the high liquid level (HLL) the when liquid that accumulates in the liquid storage room is in starting, ready for starting next time, realized " drainage, lifelong self-priming ".
As further improvement of the utility model, described seal arrangement is packing seal and the outside framework oil seal that places in the Stuffing box, the pump cover upper-end surface of the lower end surface of Stuffing box and its below is respectively equipped with downward step and the step that makes progress, form the back blades chamber, in the back blades chamber, be provided be installed on the pump shaft, the back blades more than a group, rotate the formation dynamic seal by back blades with pump shaft, liquid enters in the Stuffing box in the prevention liquid storage room, has guaranteed the reliability that seals, has prolonged working life.
In sum, vertical self-sucking pump of the present utility model is integrated the pump housing, steam-water separation chamber, liquid storage room, integration is good, have " drainage; lifelong self-priming ", the good reliability of sealing, the characteristics of long service life again, liquid storage room deposits the effect of impurity in addition, can be because of the impurity blocking pipeline, can discharge sewage, enlarge the Applicable scope of self-priming pump.
