The utility model discloses a seal structure, provided one kind rational in infrastructure, sealing performance good, the operation safe and reliable seal structure.
Description
Technical field
The utility model relates to oil immersion type electric underwater pump, is specially a kind of sealing configuration of oil immersion type electric underwater pump.
Background technique
Oil immersion type electric underwater pump is the diving drainage and irrigation equipment of a kind of pump machine unification, it is provided with motor cavity and mechanical seal chamber at motor internal, mechanical seal and bearing is made to have good lubricating condition at work, in motor cavity, lubricant oil ensure that motor interior heat can conduct out rapidly simultaneously, good cooling results, the temperature rise of motor can be made significantly to decline, add the anti-overload ability of electric pump.
Owing to being filled with machine oil in the motor cavity of Submerged Motor Pumps, and wholely to dive beneath the water completely during work, the particular importance therefore self leakproof seal of the Butt sealing of motor internal power outlet and external power supply elastic cable paper, electric pump just seems, once seal bad, electric pump leakage of oil, motor entering water will be there is, cause heavy losses.
With regard to concrete risk of leakage, one: leak in elastic cable paper exists, namely the core in rubber insulation and the gap between core are revealed and gap in core between copper wire and copper wire is revealed.When electric pump works, motor can produce heat, electric built-in temperature is raised, due to the principle of expanding with heat and contract with cold, in motor, lubricant oil can constantly infiltrate elastic cable paper inside, if now the Butt sealing of motor inner cable line and external power supply elastic cable paper is bad, motor cavity lubricant oil can be caused to leak outside through core, thus cause motor leakage of oil; Its two: in actual using process, have certain customers oneself adjunction elastic cable paper, if its joint sealed envelope process is bad, joint is once infiltration, water will enter in elastic cable paper from cut, and the space along cable core flows in motor, causes burn-down of electric motor.
Summary of the invention
For prior art Problems existing, the utility model devises a kind of sealing configuration of oil immersion type electric underwater pump, proposes a kind of rational in infrastructure, good seal performance, sealing configuration safe and reliable to operation.
For solving foregoing problems, the utility model
A kind of sealing configuration of oil immersion type electric underwater pump, the connector cover comprising the pump housing and be tightly connected with the pump housing, form a Seal cage in connector cover and between the pump housing, connect elastic cable paper in being provided with between Seal cage and pump housing inner chamber, between Seal cage and the external world, be provided with external cable line; External cable line is connect by being wrapped in the rubber insulation of outside and being positioned at inner some cores formations in described, it is characterized in that: connect elastic cable paper in described and to block in the middle part of the internal core of with having at least in external cable line and to be connected by the wiring terminal of an entity, wiring terminal two ends are equipped with the indent interface be connected with core in-out end.
Further, above-mentioned wiring terminal and core in-out end outer side seal drive fit are enclosed with sealed insulation layer.
Further, being linked together by the indent interface of punching press and wiring terminal of upper core in-out end.
Further, the rubber insulation of above-mentioned external cable line is provided with the rubber seal that only can be passed through by core at middle part.
Further, the upper and lower sides of above-mentioned rubber seal is arranged to ramp structure.
Further, above-mentioned elastic cable paper is provided with pad and locking nut above rubber seal, and described locking nut can be threaded with the incoming line on connector cover.
The utility model realizes the wire energising of core in elastic cable paper by wiring terminal, simultaneously because the centre of wiring terminal is solid construction, all wrap up outside the in-out end of its outer surface and core by sealed insulation layer, the gap that this vibrational power flow can fundamentally be stopped in core between copper wire and copper wire is revealed, can prevent lubricant oil in motor cavity from flowing out through core, the outside water of electric pump can be stoped again to enter electric pump inner chamber through core.
In addition, the rubber seal that external cable line is arranged, its distortion and realize it and highly fit between core and connection jaws under the extruding of locking nut and pad, reach the effect of sealing, formed the sealing in gap between core and between incoming line in external elastic cable paper, the gap can fundamentally stopped in rubber insulation between core and core is revealed, and blocks outside water and enters electric pump inner chamber through elastic cable paper.
Accompanying drawing explanation
Fig. 1, the scheme of installation of the utility model seal arrangement in oil immersion type electric underwater pump;
The structural representation of Fig. 2, the utility model external cable line.
Embodiment
As illustrated in fig. 1 and 2, a kind of sealing configuration of oil immersion type electric underwater pump, the connector cover 2 comprising the pump housing 1 and be tightly connected with the pump housing 1, a Seal cage 21 is formed in connector cover 2 and between the pump housing 1, connect elastic cable paper 3 in being provided with between Seal cage 21 and the pump housing 1 inner chamber, between Seal cage 21 and the external world, be provided with external cable line 4.External cable line 3,4 is connect by being wrapped in the rubber insulation 41 of outside and being positioned at inner some cores 42 and forming in described.
Connect elastic cable paper 3 in described to block in the middle part of the internal core 42 of with having at least in both external cable lines 4 and to be connected by the wiring terminal 5 of an entity, be provided with wiring terminal 5 in core 42 in the present embodiment in two elastic cable papers, wiring terminal 5 two ends are equipped with the indent interface 51 be connected with core 42 in-out end.In reality processing, core 42 in-out end is linked together by the indent interface 51 of punching press and wiring terminal 5.And for the consideration of sealing, described wiring terminal 5 and core 42 in-out end outer side seal drive fit are enclosed with sealed insulation layer 6.
Above entity wiring terminal 5 structure realizes the wire energising of core 42 in elastic cable paper on the one hand, simultaneously because the centre of wiring terminal 5 is solid construction, all wrap up outside the in-out end of its outer surface and core 42 by sealed insulation layer 6, this gap can fundamentally stopped in core 42 between copper wire and copper wire is revealed, can prevent lubricant oil in motor cavity from flowing out through core 42, the outside water of electric pump can be stoped again to enter electric pump inner chamber through core 42.
In addition, the rubber insulation 41 of above external cable line 4 is provided with the rubber seal 7 that only can be passed through by core 42 at middle part, and for optimizing the consideration of deformability, the upper and lower sides of rubber seal 7 is arranged to ramp structure 71.Described external cable line 4 is provided with pad and locking nut 9 above rubber seal 78, and described locking nut 9 can be threaded with the incoming line 22 on connector cover 2.
When assembling, rubber seal 7 distortion and realize and highly fit between core 42 and connection jaws 22 under the extruding of locking nut 9 and pad 8, reach the effect of sealing, formed the sealing in gap between core 42 and between incoming line 22 in external elastic cable paper 4, the gap can fundamentally stopped in rubber insulation between core 42 and core 42 is revealed, and blocks outside water and enters electric pump inner chamber through external cable line 4.
This novel sealing structure is mainly used on oil immersion type electric underwater pump, under 1.5MPa external pressure and 1.5MPa inner pressure test condition, realize 72 hours durable and do not leak, sealability is very good.
