Description

TECHNICAL FIELD

[0001] The utility model relates to high lift circulating pump production technical field especially relates to a pump shaft polishing device of high lift circulating pump. BACKGROUND

[0002] The pump shaft plays a crucial role in the high-lift circulating pump. Here are several main roles of the pump shaft in the high-lift circulating pump: 1) Power transmission: The pump shaft is a key transmission component in the high-lift circulating pump. It is connected to the motor shaft through a coupling at one end and supports the impeller for rotational movement at the other end. In this way, the torque of the motor can be transmitted to the impeller through the pump shaft, allowing the impeller to rotate at high speed. 2) Support the impeller: The pump shaft not only transmits power but also supports the impeller, ensuring that the impeller can maintain its working position and operate normally. This is particularly important for high-lift circulating pumps, as the high-speed rotation and efficient water output of the impeller depend on the stable support of the pump shaft. 3) Maintain system stability: The pump shaft helps maintain the stable operation of the entire high-lift circulating pump system through its stable transmission and support. It ensures that water flows smoothly from the water inlet into the pump body, accelerates through the rotation of the impeller, and then is output at high pressure from the water outlet.
