Problems solved by technology

[0002] In order to obtain a higher head of the water pump, it is necessary to install multi-stage impellers and guide components on the pump shaft. However, with the increase of the impeller, the running stability of the motor in the water pump will decrease, which will affect the performance of the water pump. Therefore, how to effectively improve the performance of the motor? Stability at runtime is especially important

Abstract

The invention discloses a motor limiting structure of a multi-stage pump, which can effectively improve the stability of the rotation of the motor shaft. The key points of the technical solution include a motor barrel, a motor and a motor shaft, and the motor and the motor shaft are installed in the motor barrel. The two ends of the motor barrel are respectively provided with an upper connecting seat and a lower connecting seat. Both the upper connecting seat and the lower connecting seat include a shaft hole through which the shaft of the power supply passes. The upper thrust structure, the thrust includes the upper friction plate, the lower friction plate and the thrust seat arranged in sequence from top to bottom, the top of the lower connection seat is provided with a spherical groove, and the bottom surface of the thrust seat is provided with a spherical groove. The matching spherical bump, the invention is applicable to the technical field of water pumps.

Description

technical field [0001] The invention belongs to the technical field of water pumps, in particular to a high-stability thrust structure of a multi-stage pump. Background technique [0002] In order to obtain a higher head of the water pump, it is necessary to install multi-stage impellers and guide parts on the pump shaft. However, with the increase of the impeller, the running stability of the motor in the water pump will decrease, which will affect the performance of the water pump. Therefore, how to effectively improve the performance of the motor? Runtime stability is especially important. Contents of the invention [0003] The purpose of the present invention is to provide a motor position limiting structure of a multi-stage pump, which can effectively improve the stability of the motor shaft rotation. [0004] The object of the present invention is achieved in the following way: a motor limiting structure of a multi-stage pump includes a motor barrel, a motor and a m...
