Abstract
The invention relates to a quadruple sealing structure of a cable of a submersible electric pump. The quadruple sealing structure comprises a cable and a junction box, wherein a first seal is arranged at the terminal of the cable; a second seal and a third seal are arranged at the sleeve joint of the cable and the junction box; and a fourth seal is arranged at the tail end of the cable. The first seal is arranged at the terminal of the cable, the second seal and the third seal are arranged at the sleeve joint of the cable and the junction box, and the fourth seal is arranged at the tail end of the cable, so the quadruple sealing structure has a novel structure, low production cost and a good quadruple sealing effect of the cable, is convenient to process, is effectively isolated from water or damp air, solves the problem that the traditional seal has high probability of failures, and prolongs the service life of a diving electric device.
Description
Technical field
The present invention relates to a kind of hermetically-sealed construction, particularly a kind of quadruple hermetically-sealed construction of submersible pump cable.
Background information
Submersible pump cable seal waterproof is directly to influence submersible motor reliability key factor, and reprocessing has 70% all to be because the cable water inlet causes coil to make moist until burning in the electric pump.The main path one of cable water inlet is that damaged whose gap between core of cable sheath gets into motor, the 2nd, and the damaged water of cable core gets into motor along the gap between the inner copper wire of core.
Traditional submersible pump cable inlet wire sealing just at the terminal box place of immersible pump, through regulating hold-down bolt, is once compressed with rubber ring; Thereby come cable is sealed, it the damage of cable root occurs in actual use easily; Water pump is in transportation, installation, use, and the water pump cable receives the influence of external pull, is easy to generate loosening; Thereby the inlet wire seal failure, and cause the water inlet of cable place, make motor intake, burn.
Summary of the invention
The objective of the invention is to overcome the problem that prior art exists, proposed a kind of quadruple hermetically-sealed construction of submersible pump cable of simple in structure, good sealing effect.
In order to achieve the above object, the technical scheme of the present invention's employing is:
A kind of quadruple hermetically-sealed construction of submersible pump cable; Comprise cable, terminal box; Its technical characterstic is: said cable termination is provided with first sealing, and said cable and terminal box socket place are provided with second sealing and the 3rd sealing, and said cable end piece is provided with the 4th sealing.
Said first sealing comprises wire barrel, interior heat-shrinkable T bush and insulating tape; Cable termination be connected in wire barrel by terminals; Wire barrel is provided with interior heat-shrinkable T bush outward, and interior heat-shrinkable T bush, interior heat-shrinkable T bush and cable termination socket place, interior heat-shrinkable T bush and cable all are coated with insulating tape on the terminals socket place outer wall.
Said second sealing comprises cable feedthrough and the inlet wire sealing ring that all is connected on the cable, and the inlet wire sealing ring is arranged between cable and the terminal box, and the cable feedthrough that compresses the inlet wire sealing ring lock onto on the terminal box.
Said the 3rd sealing comprises the cable feedthrough that all is connected on the cable, little gland and gland ring, and gland ring is arranged between cable and the cable feedthrough, and the little gland that compresses gland ring lock onto on the cable feedthrough.
Said the 4th sealing comprises on outer heat-shrinkable T bush, outer heat-shrinkable T bush the strip off copper wire part that is wrapped in cable end piece and the outer wall that insulate, between the strip off copper wire of cable end piece, be provided with the tin seal between copper wire and the insulation outer wall.
Be equipped with compacting ring between said gland ring and cable feedthrough, cable feedthrough and inlet wire sealing ring, inlet wire sealing ring and the terminal box.
Compared with prior art; The beneficial effect that the present invention reaches is: cable termination with docked back socket wire barrel by terminals; On the wire barrel in the socket behind the heat-shrinkable T bush by the insulating tape sealed package, can effectively prevent the gap seepage of terminal box inner cable butt joint junction; The 4th sealing of cable end piece is provided with outer heat-shrinkable T bush, can effectively prevent the gap seepage of cable end piece junction; Second sealing and the 3rd sealing are respectively equipped with inlet wire sealing ring and gland ring, can prevent effectively that sealing gets in the terminal box along the cable outer wall; Be provided with the tin seal in the 4th sealing, effectively between the strip off copper wire, the gap seepage between copper wire and the cable insulation outer wall.
The present invention is provided with first sealing at cable termination, and cable and terminal box socket place are provided with second sealing and the 3rd sealing, and cable end piece is provided with the 4th sealing; Its novel structure, easy to process, production cost is low; Cable quadruple good sealing effect; Can effectively completely cut off moisture or humid air, solve the problem that conventional seals lost efficacy easily, increase the useful life of diving electric device.
