Abstract
The utility model discloses a deep-well pump lead connection structure. A PVC pipe is sleeved between adjacent lead terminations. The adjacent lead termination portions possess a silver welding layer. The PVC pipe is sleeved on a position corresponding to the silver welding layer. A silica gel layer is arranged between the PVC pipe and the silver welding layer. According to the utility model, silver brazing is used to replace a crimping technology so that a welded junction is firm and reliable. A flame-retardant PVC short tube is used to pour the silica gel so that water can be prevented from entering into a thread residue. By using the above structure, problems of soaking, insulation reduction, short circuit, open circuit, electric leakage, grounding and the like generated because a lead joint is in the water for a long time and a water surface pressure is generated can be solved. The structure can be widely used in deep-well underwater lead connection.
Description
Technical field:
The utility model relates to the connection of lead, particularly the conductor connecting structure under the phreatic water.
Background technology:
Lead under the existing phreatic water connects, crimping structure is generally adopted in the processing of joint, soldering or common brazing weld together, insulation processing adopts self-adhesive tape and plastic adhesive tape wrapping, connection the end of a thread of making like this is loosening, immersion or oxidation easily, so produce insulativity reduction, electric leakage, short circuit, a difficult problem such as open circuit.
The utility model content:
The utility model provides a kind of deep well pump conductor connecting structure at above deficiency exactly, this structure adopts silver brazing technology to carry out the end of a thread connection, with flame-proof PVC short tube filling silica gel, fundamentally block up and cut off the pernicious fault that infiltration, electric leakage, the end of a thread oxidation and insulation descend and cause again.
Technical solution adopted in the utility model is:
A kind of deep well pump conductor connecting structure, adjacent wires is socketed with pvc pipe between the termination, and adjacent wires termination portion has the silver soldering layer, and pvc pipe is socketed in the position of corresponding silver soldering layer.
Has layer of silica gel between pvc pipe and the silver soldering layer.
The two ends of pvc pipe have sealant.
The outside of one or more pvc pipes also is provided with insulating cement belt and marine glue belt.
The beneficial effect that the utility model enough reaches is:
1, the utility model replaces compression joint technique with silver brazing, makes weld bond solid and reliable: annotate silica gel with the flame-proof PVC short tube and prevent the end of a thread water inlet.Above-mentioned 2 points, can solve terminal because of the immersion that is in for a long time in the water and water surface pressure produces, insulation reduction, short circuit, open circuit and problems such as electric leakage, ground connection.
2, the utility model flame-proof PVC pipe good toughness, water-impervious, intensity height, external insulating tape and adhesive waterproof tape, insulation and good water-proof effect, long service life, be applied to table mountain, Henan Province Ye County institute of traditional Chinese medicine and the energy-conservation central air conditioning project of Ye County county government earth source heat pump, through operation test, respond well, safe and reliable.
Description of drawings:
Fig. 1 is structural scheme of mechanism of the present utility model.
Embodiment:
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, this deep well pump conductor connecting structure, be socketed with pvc pipe 1 between the adjacent wires termination, adjacent wires termination portion has silver soldering layer 2, pvc pipe 1 is socketed between the position of corresponding silver soldering layer 2 and pvc pipe 1 and the silver soldering layer 2 has layer of silica gel 3, the two ends of pvc pipe 1 seal by sealant 4, and the outside of three pvc pipes 1 also is provided with insulating cement belt 6 and marine glue belt 5.Add and do silver brazing, silicone insulation processing man-hour earlier, with high-purity alcohol the end of a thread face of weld is done preservative treatment then, alcohol is ethanol, copper in the end of a thread is oxidized because welding, quality just can descend behind the copper cupric oxide, and cupric oxide dips in alcohol, can be reduced to copper by alcohol, CH3CH2OH+CuO------CH3CHO+Cu+H2O.And the good toughness of flame-proof PVC pipe 1, water-impervious, intensity height.By above processing, can solve in deep well pump conductor connecting structure and the insulation processing problems such as terminal oxidation, the reduction of becoming flexible, soak, insulate substantially.
