The specific embodiment
As shown in the figure, a kind ofly be applied to adopting in the water resource heat pump waring and cooling air conditioning system and irritate the well ground installation, comprise adopt filling to well, be installed on the face of land and adopt the pipe-line system that filling is connected to well, described pipe-line system is recharged pipeline section 2, draining by waterline 1, pump line and is returned and raise pipeline section 3, shared pipeline section 17, well head 4 and pump line sealing device, spinning liquid and remove sand filter and survey water level pipe and form, described waterline is connected with the pipeline section that spinning liquid removes sand filter 5 by flow pipe, and its effect is to carry underground water to source pump.Pump line recharges pipeline section and recharges valve 18 and pump line and draining by pump line and return and raise pipeline section and be connected, and its effect is that the unit discharge water is recharged to underground by pump line.Draining is returned and is raised pipeline section and adopt filling well is connected, and its effect is sewage when initial and the discharging of waste water when pumping up water pulling vacuum with turn on pump.Adopt filling well well head top is connected with sealing device, its underpart connects the diving pump line, sealing device is the special facilities of sealing well head, its effect is except that the passage that water delivery and pump line recharge, it mainly is the sealing well head, prevent to cause when pressure from recharging recharge water excessive, and when the pump line vacuum is recharged, do not leak, keep the vacuum in pump line and the pipeline.Described sealing device mainly contains wellhead flange 6, seal gasket 7, seal disc 8, water exit elbow 9, automatic exhaust steam valve 10, Pressure gauge 11, thermometer 12, the described universal flange 13 that is connected with the universal elbow of well head is connected with well head seal disc 8, the wellhead flange 6 that the well head seal disc is connected with well casing 14 is tightly connected by seal gasket 7, the universal elbow of well head is connected with pump line 15, be equipped with automatic exhaust steam valve, Pressure gauge on the well head seal disc, pump line pressure vacuum gauge 11, thermometer 12 are housed on the universal elbow of well head.Survey water level pipe 16 end openings and be connected suitable for reading placing more than the ground with well casing.Survey the water level pipe end opening and weld 62 millimeters seamless steel pipes of Φ to more than the ground at 140 meters of well casing, so as under the situation of well head sealing the energy measurement water level, check and adopt an important device of irritating under the well duty.Sealing is the key issue that vacuum is recharged in this device.Sealing just can not form vacuum when vacuum is recharged fortunately, just can't utilize siphon principle to produce head difference and recharge, and air is sucked in the water-bearing layer cause the gas phase clogging, and what influence was recharged normally carries out.Vacuum is recharged the position that needs sealing and is mainly contained the Pressure gauge installed on pump pipe union, wellhead flange, gate valve, the pump line, thermometer etc. and connect and form.Vacuum is recharged under the condition that is meant formation-0.1Mpa pressure in pump line, by pump line recharge water is poured into a kind of method in water-bearing layer, down-hole, and its technological process is as follows: recharge in the process in vacuum, abstain from that air enters in the well most.But positive confinement is unapproachable, more or less can leak gas a little when recharging.Should measure vacuum size in the pipeline with vacuum meter.It is generally acknowledged: vacuum is during for-0.06-0.07Mpa, good sealing effect; When vacuum during less than-0.05Mpa, seal degree is poor, should keep in repair mending-leakage immediately.Termination of pumping behind Hui Yang, close by-pass valve control, then vacuum meter shows negative pressure, as not thinking at this moment that less than-0.06Mpa sealing effectiveness is fine, needs to remain unchanged substantially after 8 hours or do not drop to below the 0.05Mpa, just can carry out vacuum and recharge.When recharging, vacuum should note: necessary Hui Yang regularly, and return the time of raising and decide according to the unimpeded situation of inverted well, general one day Hui Yang is once, and is each 20-40 minute, clean to the water sand removal; The amount of recharging should ascendingly increase gradually when the inverted well initial stage used, in order to avoid excessive because of the reverse flow effect, the impact filtration layer causes water flowing not smooth; Adopt filling well is answered annual well-flushing once for irritating to adopt mutually with well, silt up, influence the service life of well to prevent drainage layer accumulative total.Adopt filling well ground installation by improvement, adopt the negative pressure recirculation process to control the inverted well water level effectively and rise, improved the amount of recharging, make the average filling amount of adopting reach 45.3m respectively
3/ h (winter) 55.28m
3/ h (summer), maximum is irritated the amount of adopting and is reached 84m
3/ h still has the amount of adopting of filling to increase leeway.Irritate when adopting balance when reaching, the unit amount of recharging reaches 0.504: 1 with the ratio of specific capacity, and individual well self is irritated to adopt and reached 0.74: 1, adopts than improving more than the twice than the filling of the inverted well of static use.Under the situation that guarantees two season of summer in winter indoor temperature standard, solved key issue to the well irrigation extraction system in same water-bearing layer comprehensively.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
