Submersible pump motor facilitating heat dissipation

Abstract

The invention discloses a submersible pump motor facilitating heat dissipation. The submersible pump motor comprises a motor casing, wherein an upper end cover is fixedly connected to the upper end ofthe motor casing, a lower end cover is fixedly connected to the lower end of the motor casing, a vertical rotary shaft is arranged inside the motor casing, a rotor is fixedly connected to the side wall of the rotary shaft in a sleeving mode, the upper end of the rotary shaft is rotationally connected with the upper end cover through a first rolling bearing, the lower end of the rotary shaft penetrates through the lower end cover and extends outside, the lower end of the rotary shaft is rotationally connected with the lower end cover through a second rolling bearing, a stator corresponding tothe position of the rotor is fixedly arranged on the inner side wall of the motor casing, a tank is fixedly arranged at the upper end of the outer side wall of the motor casing, a horizontal first rotary rod is arranged inside the tank, and the two ends of the first rotary rod are rotationally connected with the two side walls of the tank through third rolling bearings. According to the submersible pump motor, heat dissipation can be effectively performed on the motor through cooling liquid which flows repeatedly, and heat outside the motor can be isolated, so that influence on motor working is avoided.

Description

technical field [0001] The invention relates to the technical field of motor production, in particular to a motor for a submersible pump that is easy to dissipate heat. Background technique [0002] Submersible pump is an important equipment for deep well water extraction. When in use, the whole unit submerges into the water to extract groundwater to the surface. It is used for domestic water, mine emergency, industrial cooling, farmland irrigation, seawater lifting, ship load adjustment, and can also be used for fountain landscape. [0003] Motors for submersible pumps are widely used in various fields of industrial and agricultural production and life. When the submersible pump is working, the motor will generate heat. Since the motor in the submersible pump is seamlessly sealed, the heat is difficult to dissipate. It is easy to cause damage to the motor for a long time , especially when working in geothermal wells or water with high temperature, it is easy to burn the mot...
