Abstract
The utility model belongs to the technical field of submersible motors and particularly relates to an improved medium-sized submersible motor cable sealing structure which mainly comprises a gland and a cavity. The center of the gland is provided with a cable channel, and the gland and the cavity are in threaded connection. The improved medium-sized submersible motor cable sealing structure is characterized in that a metal gasket and a cable sleeve are arranged between the gland and the cavity, the lower end of the cavity is provided with a chamber for filling a sealing material, and the connection part of the cavity and a motor is provided with a triangular lug which can adjust the amount of compression of an O-shaped ring. The improved medium-sized submersible motor cable sealing structure can realize secondary sealing. The gland with a cable channel and the cavity are in threaded connection; the metal gasket and the cable sleeve are arranged between the gland and the cavity; the gland and the cavity seal jointly; and the chamber on the lower end of the cavity realizes secondary sealing by filling the novel sealing material as the filler. The overall performance of the improved medium-sized submersible motor cable sealing structure is superior to that of the existing structure, and the improved medium-sized submersible motor cable sealing structure guarantees the reliability of the submersible motor and is simple in structure and convenient to assemble and disassemble.
Description
Technical field
The utility model belongs to medium-sized submersible motor technical field, is specifically related to improved cable seal structure on a kind of medium-sized submersible motor.
Background technology
The cable seal of submersible motor has had a variety of structures in practical application, thereby wherein most of structure does not all have secondary seal to influence motor seal.
Summary of the invention
The purpose of the utility model is the above-mentioned defective that on comprehensive existing medium-sized submersible motor hermetically-sealed construction basis, exists to prior art, and cable that provides and cable joint-box still can guarantee a kind of cable seal structure of sealing property when strain becomes plastic deformation.
The technical scheme of the utility model: medium-sized diving generator cable hermetically-sealed construction, comprise that there is the gland and the cavity of cable passage at the center, be threaded between gland and the cavity, it is characterized in that between gland and cavity, being provided with metallic gasket and cable joint-box; The cavity lower end is provided with the chamber of perfusion encapsulant; The connecting portion of cavity and motor is provided with the triangular hill of scalable O type circle decrement.
Usually, the screw thread on the utility model gland has enough length, guarantees can continue compression after it reaches decrement; Adopt four screws to be connected between cable seal structure and the motor body.
The utility model hermetically-sealed construction has secondary seal, be threaded between the gland with cable duct and the cavity, between metallic gasket and cable joint-box are arranged, form sealing in that gland is common between cavity; The chamber of cavity lower end through perfusion sealing material filler, forms secondary seal.Improved structure is superior to existing structure on overall performance, guaranteed the reliability of submersible motor, and is simple in structure, easy accessibility.
Description of drawings
Accompanying drawing 1 is the cross-sectional schematic of the utility model embodiment hermetically-sealed construction.
Among Fig. 1,1-cable passage; 2-gland; 3-triangular hill; 4-encapsulant; 5-cavity; 6-cable joint-box; 7-metallic gasket.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is done further to describe.
Embodiment: the present embodiment structure comprises that mainly there is the gland 2 and cavity 5 of cable passage 1 at the center shown in accompanying drawing 1, is threaded between gland 1 and the cavity 5, and its main feature is between gland 2 and cavity 5, to be provided with metallic gasket 7 and cable joint-box 6; Cavity 5 lower ends are provided with the chamber of perfusion encapsulant 4; The connecting portion of cavity 5 and motor is provided with the triangular hill 3 of scalable O type circle decrement, this triangular hill, and its dimensional requirement still can continue compression after O type circle reaches compression limit.
Specifically; Present embodiment is on gland 2, to be provided with cable duct 1, and there is metallic gasket 7 gland 2 lower ends, and metallic gasket is for 7 times a cable joint-box 6; Be provided with chamber in the cavity 5 of cable joint-box 6 belows; Can pour into sealing material 4, treat that promptly cable passes cable passage 1 back perfusion liquid sealing material 4 and its heating is guaranteed to fill up chamber and cable passage 1 gap, becomes solid-state formation secondary seal after encapsulant 4 coolings.
Present embodiment is provided with triangular hill 3 at the connecting portion of hermetically-sealed construction and motor body, and this version is the new structure outside the GB/T3452.3-1988, both can regulate the amount of contracting of connecting portion O type circle, can satisfy O type circle operating specification again.
When present embodiment is installed; Cable passes cable passage 1, gland 2, metallic gasket 7, cable joint-box 6 and cavity 5; Tighten the screw thread between gland 2 and the cavity 5, after the perfusion encapsulant treated that it solidifies in cavity 5 again, black box integral body was fastened on the motor body with screw.Only need get final product for one time during dismounting by the said sequence contrary operation.
In order to reach sealing effectiveness better, the screw thread on the present embodiment gland 2 has enough length, guarantees can continue compression after it reaches decrement; Adopt four screws to be connected between cable seal structure and the motor body.
