Embodiment Construction

[0021] Such as figure 1 As shown, the joint protection structure of a deep submersible electric pump cable of the present invention includes a high-pressure heat-shrinkable tube 2 and an interconnected power cable 1 and a motor lead-out cable 7 installed in the high-pressure heat-shrinkable tube. The power cable and the motor lead-out cable Teflon tape layer 6 , self-dissolving ethylene propylene rubber tape layer 5 , polyvinyl fluoride tape layer 4 and plastic tape layer 3 are respectively wrapped at the cable connection, from inside to outside to the high-pressure heat shrinkable tube.

[0022] this invention figure 1 The manufacturing method of the joint protection structure of the shown deep submersible electric pump cable is as follows:

[0023] 1) Welding and pretreatment:

[0024] a. Weld the power cable and motor lead-out cable;

[0025] b. Clean up the welding slag on the welding part, file off the sharp corners and burrs;

[0026] c. Scrub the welding surface and...

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....
