Problems solved by technology

[0002] In domestic engineering, mining, sewage treatment and municipal construction projects, a large number of large and medium-sized submersible pumps are used. However, many submersible pumps have not dealt with the problem of cable sealing, so that the cables of the submersible pumps enter water and cause the cables to leak. The insulation of the submersible pump is reduced, which will cause the motor of the submersible pump to burn out or become unusable
At present, the cable seals of large and medium-sized submersible pumps in China are sealed by cable seal rings according to the traditional design. , but did not completely solve the cable sealing problem and needs to be improved

Abstract

The invention discloses a cable sealing structure of a submerged motor pump. The structure comprises a cable, a cable sealing ring, a gland nut, a cable sealing ring sealing surface and an upper end cover. The cable is sleevedly connected into the cable sealing ring; the cable sealing ring is fixed on the upper end cover by the gland nut; the cable includes a triple-phase line and a grounding wire, wherein the triple-phase line and the grounding wire are respectively sealed on the upper end cover; and a core wire of the triple-phase line is connected with a core wire of a motor lead through a clamping copper tube that is tightly wrapped by a heat-shrink tube and a waterproof adhesive tape. Compared with the prior art, the technology employed in the invention enables the provided cable sealing structure of a submerged motor pump to solve a cable sealing problem; besides, waterproof and moisture proof performances are realized; and it can be avoided that an electric pump motor is damaged due to water inlet or moisture absorption.

Description

technical field [0001] The invention relates to the field of electric pumps, in particular to a cable sealing structure of a submersible electric pump. Background technique [0002] In domestic engineering, mining, sewage treatment and municipal construction projects, large and medium-sized submersible pumps are widely used. However, many submersible pumps have not dealt with the problem of cable sealing, so that the cables of the submersible pumps enter water and cause the cables to leak. The insulation of the submersible pump is reduced, which will cause the motor of the submersible pump to burn out or become unusable. At present, the cable seals of large and medium-sized submersible pumps in China are sealed by cable seal rings according to the traditional design. , but it does not completely solve the cable sealing problem and needs to be improved. Contents of the invention [0003] In view of the above defects, the technical problem to be solved by the present inven...
