Electric submersible pump capable of being assembled and disassembled conveniently

Abstract

The invention relates to the technical field of electric submersible pumps, and discloses an electric submersible pump capable of being assembled and disassembled conveniently, which comprises an upper casing. The inner side surface of the upper casing is fixedly connected with a multi-stage centrifugal pump, the bottom of the upper casing is provided with a lower casing, the inner side surface ofthe lower casing is fixedly connected with a motor rack, the inner part of the motor rack is fixedly installed with a motor, the top of the motor rack is provided with a fixing rack, the left side and the right side of the fixing rack are fixedly connected with the inner side surface of the lower casing, the inner side surface of the fixing rack is fixedly provided with a protector, the output shaft of the motor runs through and extends to the inner part of the protector through a coupling, the top part of the protector is fixedly connected with a flexible shaft, the top end of the flexible shaft runs through and extends to the inner part of the multi-stage centrifugal pump, and the inner part of the upper casing is provided with a locking rod groove. According to the electric submersiblepump capable of being assembled and disassembled conveniently, assembly and disassembly are convenient, and the service life of the electric submersible pump is significantly enhanced.

Description

technical field [0001] The invention relates to the technical field of electric submersible pumps, in particular to an electric submersible pump which is easy to assemble and disassemble. Background technique [0002] The electric submersible pump is a multi-stage centrifugal pump working underground. It is lowered into the well together with the oil pipe. The ground power supply transmits electric energy to the underground submersible motor through the transformer, control panel and power cable, so that the submersible motor drives the multi-stage centrifugal pump to rotate. Convert electrical energy into mechanical energy to lift the well fluid in the oil well to the surface. [0003] At present, the electric submersible pumps on the market have the advantage of reducing noise, but in the actual use process, when the electric submersible pumps on the market are damaged, they cannot be repaired in time because of the integrated structure, and they all need to be returned to...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a submersible electric pump that is easy to disassemble and assemble, which has the advantage of being easy to disassemble and assemble, and solves the problem that the submersible electric pump currently on the market is damaged due to integration during actual use. structure and cannot be repaired in time, they all need to be returned to the factory for maintenance, and the existing submersible pumps are inconvenient to disassemble, and the impurities in the submersible pumps are difficult to clean up. Impurities have the risk of damaging the electric submersible pump
