Joint protective structure of deep diving electric pump cable and making method thereof

Abstract

The present invention discloses a joint protective structure of a deep diving electric pump cable and a making method thereof. The joint protective structure of a deep diving electric pump cable comprises a high-pressure heat-shrink pipe, a power cable and a motor lead-out cable, wherein the power cable and the motor lead-out cable are arranged in the high-pressure heat-shrink pipe, and are mutually connected; a Teflon tape layer, an autolytic ethylene propylene rubber tape layer, a polyfluoroethylene tape layer and a plastic adhesive tape layer are respectively bound up at the connection position of the power cable and the motor lead-out cable from the inner side to the outer side to the high-pressure heat-shrink pipe. The making method comprises the steps of welding, preprocessing, binding-up insulation processing and heating sealing. The insulation sealing performance of the joint protective structure of a deep diving electric pump cable is good; the applicability of a diving electric pump motor under the state of deep diving is ensured; the diving electric pump cable is ensured to enter water below 600 m; and the joint protection structure of a deep diving electric pump cable can be safely used.

Description

technical field [0001] The invention relates to an electric pump structure and a manufacturing method thereof, in particular to a joint protection structure of a deep submersible electric pump cable and a manufacturing method thereof. Background technique [0002] The Chinese Utility Model Patent No. 200520068532 and the title of the invention are "the joint protection structure of oil-filled submersible pump cables and windings" discloses a joint protection structure for oil-filled submersible pump cables and windings, which includes sequentially from inside to outside The rubber insulating tape and plastic adhesive tape wrapped outside the joint are oil-resistant sealants on the outside of the plastic adhesive tape, and the outside of the oil-resistant sealant is a sealed chamber composed of rubber columns, oil-resistant rubber sleeves, cables, and magnet wires. The electromagnetic wire passes through the middle of the rubber column and fits tightly with the rubber column....

AI Technical Summary

Problems solved by technology

[0003]The above structure has many sealing places and the sealing is complicated. The cable terminal head and the intermediate joint of the deep submersible electric pump are important parts in the cable line, and their function is to disperse the cable The electric field at the cut-off point of the outer shield of the terminal head protects the cable from being broken down, and also has the functions of internal and external insulation and waterproofing.
