Technical field
The utility model relates to a kind of submersible pump, and more particularly, it relates to a kind of submersible pump that prevents motor entering water.
Background technique
Submersible pump is the visual plant of deep-well water lift, the whole unit work that pulls the plug when use.
While use due to submersible pump, be immersed in for a long time in water, the sealing at the cable joining place on motor housing is just played critical effect to submersible pump, easily enters motor internal if seal bad moisture, causes burn-down of electric motor, and submersible pump cannot normally use.
The seal ring at the cable joining place of traditional submersible pump is after using for a long time, and seal ring there will be skew and loosening.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of submersible pump that prevents motor entering water.
For achieving the above object, the utility model provides following technological scheme: a kind of submersible pump, comprise pump body and motor, described motor is provided with output revolving shaft, described rotating shaft is provided with impeller and is located in described pump body interior, described pump body is provided with the intake pipe and the outlet conduit that communicate, described impeller is positioned at intake pipe and outlet conduit intersection, on described motor housing, be equipped with cable, on described cable, be arranged with seal ring, described seal ring comprises sealed department and lower seal portion, the diameter of described lower seal portion is greater than the diameter of sealed department, described lower seal portion is positioned at described motor housing, described upper sealed department is positioned at outside described motor housing, described upper sealed department is arranged with closing sleeve and cable feedthrough, described closing sleeve is positioned at described cable feedthrough top, described cable feedthrough is threaded with described motor housing, the inwall of described closing sleeve is provided with some energy radial dilatation and has flexible embedding part, described embedding part is circular-arc and a side is fixedly connected with described closing sleeve inwall, opposite side is free side.
By adopting technique scheme, because the lower seal portion diameter of seal ring is greater than upper sealed department diameter, make like this cable feedthrough press seal circle simultaneously, and can limit moving axially of seal ring, the embedding part of closing sleeve inwall is making itself and upper sealed department realize interference fit, clamp like this effect highly significant, and convenient disassembly, further improve the axial seal effect of seal ring, like this after long-time use, even if becoming flexible appears in being threaded of cable feedthrough, closing sleeve still can ensure that the position of seal ring is not offset, play the effect of duplicate protection.
The utility model is further set to: described embedding part is two and for ring-type, the free side of described embedding part arranges in opposite directions and do not touch.
By adopting technique scheme, the free side of two embedding parts arranges in opposite directions and can reach good clamping effect, and embedding part is that ring-type can realize the omnibearing clamping of seal ring, and then significant sealing affection.
The utility model is further set to: the outer surface of described motor housing is provided with some bulge loops, and described cable feedthrough is provided with the annular groove coordinating with described bulge loop.
By adopting technique scheme, the cooperating structure of bulge loop and annular groove forms good labyrinth seal, and liquid cannot be entered from the radial direction of cable, and sealing effect is more comprehensively with effective.
The utility model is further set to: described embedding part is made up of plastic materials.
By adopting technique scheme, plastic materials has certain elasticity, can realize clamping effect, and it is to the not external protection of fragile cable of the clamping of cable, and cost is low and moulding is simple.
