[0002] A pump is a machine that transports fluids or pressurizes fluids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids. The pump shaft is the basis for a pump to stably transport fluids or liquids. The pump shaft needs to rotate at high speed during operation. If the surface of the pump shaft is not well treated, the friction of the pump shaft will increase, causing the pump shaft rotation direction to deflect, reducing the service life of the pump shaft.

The manual polishing method is not only inefficient, but also cannot guarantee the polishing quality of the pump shaft. When the mechanical contact polishing method is used, it is firstly unable to achieve the stability and horizontal placement of the pump shaft during the placement process, and the pump shaft is prone to deflection during the polishing process, resulting in uneven distribution of the size of the pump shaft, thereby causing quality damage.
