Abstract
The utility model relates to a quadruple leakproof structure of a submersible electric pump cable. The quadruple leakproof structure comprises a cable and a junction box. A cable terminal is provided with a first seal. A joint position of the cable and the junction box is provided with a second seal and a third seal. A tail end of the cable is provided with a fourth seal. The cable terminal is provided with a first seal. The joint position of the cable and the junction box is provided with a second seal and a third seal. A tail end of the cable is provided with a fourth seal. The quadruple leakproof structure is novel in structure, convenient in processing, low in production cost, and the cable has good quadruple leakproof effect. The quadruple leakproof structure effectively isolates moisture or moist air, solves a problem that a conventional seal is easy to lose efficacy, and increases service life of diving electric devices.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, particularly a kind of quadruple hermetically-sealed construction of submersible electric pump cable line.
Background technology
The submersible electric pump cable water-tight is directly to affect submersible motor reliability key factor, and reprocessing has 70% all to be because the cable water inlet causes coil to make moist until burn in the electric pump.The main path one of cable water inlet is that damaged whose gap between core of cable sheath enters motor, the 2nd, and the damaged water of cable core enters motor along the gap between the copper wire of core inside.
Traditional submersible pump cable incoming seal is just at the terminal box place of immersible pump, by regulating hold-down bolt, carry out first compression with rubber ring, thereby come cable is sealed, it the damage of cable root easily occurs in actual use, water pump is in transportation, installation, use procedure, the water pump cable is subject to the impact of external pull, easily produce and become flexible, thereby incoming seal lost efficacy, and cause cable place water inlet, so that motor entering water, burn.
Summary of the invention
The purpose of this utility model is to overcome the problem that prior art exists, and has proposed a kind of quadruple hermetically-sealed construction of submersible electric pump cable line of simple in structure, good sealing effect.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of quadruple hermetically-sealed construction of submersible electric pump cable line, comprise cable, terminal box, its technical characterstic is: described cable termination is provided with the first sealing, and described cable and terminal box socket place are provided with the second sealing and the 3rd sealing, and described cable end piece is provided with the 4th sealing.
Described the 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 outer wall, interior heat-shrinkable T bush and cable termination socket place outer wall, interior heat-shrinkable T bush and cable all are coated with insulating tape on the terminals socket place outer wall.
Described the second sealing comprises cable feedthrough and the incoming seal circle that all is connected on the cable, and the incoming seal circle is arranged between cable and the terminal box, and the cable feedthrough that compresses the incoming seal circle lock onto on the terminal box.
Described 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.
Described the 4th sealing comprises that outer heat-shrinkable T bush, outer heat-shrinkable T bush are wrapped on the strip off copper wire part and insulation outer wall of cable end piece, 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 described gland ring and cable feedthrough, cable feedthrough and incoming seal circle, incoming seal circle and the terminal box.
Compared with prior art, the beneficial effect that the utility model reaches is: cable termination with docked by terminals after the socket wire barrel, 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 docking 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; The second sealing and the 3rd sealing are respectively equipped with incoming seal circle and gland ring, can prevent effectively that sealing enters 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 utility model is provided with the first sealing at cable termination, cable and terminal box socket place are provided with the second sealing and the 3rd sealing, 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 easily lost efficacy, increase the useful life of diving electric device.
