Wet stator piece for improving stability of wet stator motor

Abstract

The invention provides a wet stator piece for improving the stability of a wet stator motor, and the wet stator piece for improving the stability of a wet stator motor comprises a wet stator piece, one end of each wet stator groove close to a through groove is provided with first chamfers, and one end of each wet stator groove far away from the through groove is provided with second chamfers. The first chamfers and the second chamfers are arranged on the wet stator grooves, so that the wet stator grooves form deep round pear-shaped structures, the sharp corner effect generated in the winding process of the cable and the wet stator grooves is completely eradicated, and the situation that the cable is in linear contact with the sharp corner is further reduced; the radian formed by the first chamfers and the second chamfers can be well matched with the circular cross section of the cable, and the insulating outermost layer of the cable is basically consistent with the contact surfaces of the grooves; the gaps between the cables are more uniform, so that the flow channels of cooling water are basically consistent, and the cooling effect brought by the cooling water is more controllable; the magnetic field generated by the laminated steel sheet group is more uniform and stable.

Description

technical field [0001] The invention relates to the technical field of wet stator motors, in particular to a wet stator sheet for improving the stability of wet stator motors. Background technique [0002] Conventional pumps and motors adopt a split connection structure with mechanical seals, resulting in natural leakage of the transmission medium. Under the working conditions of high temperature, high pressure and special medium, the design of wet stator motor is adopted, and the stator and rotor of the motor and the flow guide parts of the pump are all wrapped in a pressure vessel, which is integrated with the pipeline system, thus completely eliminating the hidden danger of leakage . Solving the design difficulties of wet stator motors mainly lies in the stability of the equipment. [0003] Due to the particularity of wet stator motors, (compared to dry motors and ordinary submersible motors) the application environment is special and the operating environment is harsh;...

AI Technical Summary

Problems solved by technology

The whole process takes about 20-40 days; it seriously affects the continuous operation of the system

Therefore, the impact caused by each insulation failure is a serious failure in the whole scope of the factory;

[0004] Therefore, there is a lack of a wet stator sheet that can still guarantee the stability of the cable insulation in a water-immersed environment.
