Description
Technical field
The present invention relates to the ground water regime technical field, specially refer to a kind of groundwater heat pump and adopt fill system well mouth seal structure and detection method thereof.
Background technology
The ground water heat pump air-conditioning system difficult point is recharging of underground water.If it is bad that well is processed, inverted well will can't reach the amount of recharging because impurity stops up, some Yangtze River Delta Area such as Shanghai, the water quality ferromanganese ion content in second water-bearing layer of the degree of depth about 100m is large, with can very fast oxidation after air contacts and produce precipitation, the deposit that produces is easy to stop up well casing worry net and causes the groundwater recharge ability to descend, if so there is air to enter in the ground water regime, if things go on like this will affect groundwater recharge even cause well to be scrapped, in case underground water well can not normally use, whole ground water heat pump air-conditioning system also will can't use because losing Cooling and Heat Source, lose huge.
The difficult point of ground water regime sealing with the sealing technique of well head.The making of pipeline can be accomplished watertight, but wellhead equipment is complicated, drinking-water pipe, recharge pipe, immersible pump and sensor cable etc., all need to pick out from well head, so sealing is not easy especially just, not only to design rational closure solutions, but also will have effective surveillance and control measure to check at any time the air-tightness of ground water regime and recharge state.
In sum, for the defective of prior art, need especially a kind of groundwater heat pump to adopt fill system well mouth seal structure and detection method thereof, to solve above-mentioned problem.
Summary of the invention
The object of the present invention is to provide a kind of groundwater heat pump to adopt fill system well mouth seal structure and detection method thereof,
Technical problem solved by the invention can realize by the following technical solutions:
A kind of groundwater heat pump is adopted the fill system well mouth seal structure, it is characterized in that, comprise the flange and the blind flange matching used with it that are welded in well head, be provided with some prepackages hole on the described blind flange, drinking-water pipe, submersible pump cable and water level thermometer cable pass the prepackage hole and extend to outside the well from well head inside, vacuum meter and the Pressure gauge of situation in the top of blind flange also is equipped with for detection of well, the place is provided with manual exhaust valve at well head.
In one embodiment of the invention, the sealing installation structure of described submersible pump cable and water level thermometer cable comprises bolt, nut and rubber ring, described nut-welding is in the top in blind flange cable prepackage hole, be provided with rubber blanket with the identical bore of nut in the hole in prepackage, bolt passes nut and compresses rubber blanket.
A kind of groundwater heat pump is adopted the detection method of fill system wellhead sealing performance, it is characterized in that, described method comprises the steps:
1) when recharging, open manual exhaust valve, when being arranged, the well water ejection is full of water to drain air in the explanation well, and this moment, valve-off was recorded the pressure on the Pressure gauge;
2) continue to recharge a period of time after, if Pressure gauge pressure rises, illustrate that then inverted well has clogging, the cleaning of need to taking measures is considered net;
3) when recharging when stopping, the water level in the well casing is because Action of Gravity Field can descend, and can produce vacuum in the well this moment, can read vacuum on vacuum meter, and when vacuum had obvious declines at short notice, illustrative system had at once repairing of leakage.
Beneficial effect of the present invention is: simple in structure, design ingeniously, and provide a kind of rational encapsulation scheme, air-tightness that simultaneously can also effective monitoring ground water regime and recharge state.
Description of drawings
Fig. 1 is the profile that groundwater heat pump of the present invention is adopted the fill system well mouth seal structure.
Fig. 2 is the top view that groundwater heat pump of the present invention is adopted the fill system well mouth seal structure.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
As depicted in figs. 1 and 2, a kind of groundwater heat pump of the present invention is adopted the fill system well mouth seal structure, comprise the flange 7 and the blind flange matching used with it 6 that are welded in well head, be provided with some prepackages hole on the described blind flange 6, drinking-water pipe 1, submersible pump cable 2 and water level thermometer cable 12 pass the prepackage hole and extend to outside the well from well head inside, the vacuum meter 10 of situation and Pressure gauge 11 are provided with manual exhaust valve 13 at the well head place in the top of blind flange 6 also is equipped with for detection of well.
The sealing installation structure of described submersible pump cable 2 and water level thermometer cable 12 comprises bolt 3, nut 4 and rubber ring 5, described nut 4 is welded in the top in blind flange 6 cables prepackage hole, be provided with rubber blanket 5 with nut 4 identical bores in the hole in prepackage, bolt 3 passes nut 4 and compresses rubber blanket 5.
The installation method that described groundwater heat pump of the present invention is adopted the fill system well mouth seal structure is as follows:
Underground water well Cheng Jinghou at the well head flange of burn-oning, reserves hole and the bolt hole of drinking-water pipe caliber at blind flange, the aboveground part of drinking-water pipe is connected with blind flange with the down-hole part, blind flange is installed on the flange that well head welds again.Blind flange also must be reserved submersible pump cable, water level thermometer cable, vacuum meter, Pressure gauge and manual exhaust valve installation position before installation.The sealing of submersible pump cable is installed, get the bolt of the suitable size of a cover, on bolt, bolt is from first to last got through the hole, with nut-welding in blind flange cable preformed hole top, be encased inside the installation site after getting the rubber blanket punching of the identical bore of nut, all opening diameters for cable just by being advisable, after cable is worn from well inside to well by hole, bolt is screwed in the nut base, the compacted rear expansion of rubber blanket, with preformed hole and cable seal, water level thermometer cable same procedure is installed, and at well head vacuum meter, Pressure gauge and manual exhaust valve is installed at last.
