Description
Technical field
This utility model is related to the sealing structure field of submersible pump, specifically a kind of submersible pump control cable seal knot
Structure.
Background technology
It is frequently found to control cable water inlet when submersible pump is reprocessed, causes stator winding to make moist and burn, therefore control cable
Sealing waterproof ability directly affects the reliability of submersible pump.The cable of submersible pump control at present is mainly close using one group of leather cup
Seal, makes on the inside of sealing ring to be formed and cable outer layer sheath between on the outside of sealing surface and sealing ring and outlet by compressing sealing ring
Compress between the inner circle of hole and form sealing surface, because only sealing function is played in the outer protective sleeve of control cable, and to cable
Without sealing between core, once cable cover(ing) is damaged, water will enter motor cavity by core.If cable the end of a thread surprisingly falls
Enter in water, the gap between the copper wire that water can be from inside core enters motor cavity.
Utility model content
The purpose of this utility model is to provide a kind of submersible pump control cable seal structure, can effectively solving submersible pump
Control cable seal enters water problems, its simple structure, good seal performance, low cost.
The technical solution of the utility model is as follows:
A kind of submersible pump controls cable seal structure, includes control cable, connector cover and cable feedthrough, its feature
It is:The outside of the control cable has the deadhead of integrally connected, and described deadhead is passed through with the sheath of the control cable
Sulfuration forms an entirety, and the deadhead is fixed and is pressed in the wire hole of the connector cover by described cable feedthrough,
The top surface of described deadhead and the connector cover wire hole, three seals face between inner circle and bottom surface, is formed respectively, constitute institute
State the outer layer sealing structure of control cable;It is whole by vulcanizing formation one between the core of the deadhead and the control cable
Body, constitutes sealing structure between the core of the control cable;The core of the control cable is welded after blocking again, Jing insulation processings
An entirety is formed by vulcanizing with described deadhead again afterwards, constitutes sealing structure between the control cable core inner conductor,
The triple of control cable are formed together with sealing structure between the core of the outer layer sealing structure and control cable of the control cable
Sealing structure.
Described submersible pump control cable seal structure, it is characterised in that:Described cable feedthrough passes through screw by institute
State deadhead to fix and be pressed in the wire hole of the connector cover.
Described submersible pump control cable seal structure, it is characterised in that:The deadhead is gone out with the connector cover
Coordinate for step between string holes.
Described submersible pump control cable seal structure, it is characterised in that:It is described control cable core block after again
Welded by copper conductor again.
The beneficial effects of the utility model:
1st, this utility model simple structure, good seal performance, low cost;
2nd, deadhead of the present utility model can either prevent cable outer layer sheath from intaking, and be prevented from water again and enter between core
Enter, when deadhead is after cable feedthrough compression, three seals face is formed between deadhead and the wire hole of connector cover, is constituted triple
Hermetic water-proof structure, can effectively prevent water from entering motor from control cable seal faying face;
3rd, by vulcanizing one entirety of formation between control cable core of the present utility model, even if the outer layer of control cable
There is breakage in sheath, water can not enter motor cavity.
4th, this utility model is welded again by blocking for core, accomplishes that electric water flowing is obstructed, even if the end of a thread unexpected overboard, water
Motor cavity will not be entered into.
Description of the drawings
Fig. 1 is this utility model structural representation.
Specific embodiment
Referring to Fig. 1, a kind of submersible pump controls cable seal structure, includes control cable 1, connector cover 5 and cable
Gland 3, the outside for controlling cable have the deadhead 2 of integrally connected, and deadhead 2 forms one by vulcanizing with the sheath 6 of control cable 1
Deadhead 2 is fixed and is pressed in the wire hole of connector cover 3 by individual entirety, cable feedthrough 3, deadhead 2 and 5 wire hole of connector cover
Top surface, form three seals face A, B, C between inner circle and bottom surface respectively, constitute the outer layer sealing structure of control cable 1;Deadhead
By vulcanizing one entirety of formation between 2 and the core 7 of control cable 1, sealing structure between the core of control cable 1 is constituted;Control
The core 7 of cable processed 1 is welded after blocking again, forms an entirety by vulcanizing with deadhead 2 again, constitute control Jing after insulation processing
Sealing structure between 1 inner conductor of cable core, with control cable 1 outer layer sealing structure and control cable 1 core between seal
Structure forms the triple seal structure of control cable together.
In this utility model, deadhead 2 is fixed and is pressed on the wire hole of connector cover 5 by screw 4 by cable feedthrough 3
In.
Be that step coordinates between the wire hole of deadhead 2 and connector cover 5, it is ensured that the elastomer of deadhead 2 and connector cover 5 it
Between compression sealing, prevent water from entering from the faying face.
The core of control cable 1 is welded by copper conductor after blocking again again.
Deadhead 2 forms an entirety by vulcanizing with the sheath 6 of control cable 1, prevents from jointly controlling the sheath 6 of cable 1
Leak, so as to substantially increase the reliability of control 1 outer layer sealing structure of cable.
By vulcanizing one entirety of formation between the core 7 of deadhead 2 and control cable 1, constitute between the core of control cable 1
Sealing structure.Its Main Function is that water can not be from control cable 1 under the unexpected breakage of 6 layers of sheath of control cable 1
Gap between core enters into motor cavity.
The core 7 of control cable 1 is welded after blocking again, whole by vulcanizing formation one with deadhead 2 again Jing after insulation processing
Body, constitutes sealing structure between control 1 inner conductor of cable core.Even if its Main Function the end of a thread unexpected overboard, water can not be from
Gap between the core of control cable 1 enters into motor cavity.Just in case water from control cable 17 inner conductor 8 of core between enter
Enter, as conductor 8 blocks welding, middle obstructed, water also reaches the end of the road, and can not leak into motor cavity, so as to prevent
Water from control 1 core inner conductor 8 of cable between enter.Its method is core peeling, and conductor 8 is dipped in after stannum fills reality and welded, and is welded
Connect outer layer and be surrounded by twolayer firing shrinkage tube 9, its internal layer is heatmeltable fluid sealant, and outer layer is insulating barrier, and conductor is packed tightly sealing after heating
And insulate.
