1. Shaft. Pumps with longer shafts are prone to insufficient shaft stiffness, too much deflection, and poor shaft straightness, which causes friction between the moving parts (drive shaft) and the static parts (sliding bearings or mouth rings), resulting in vibration. In addition, the shaft of the fluoroplastic centrifugal pump is too long, and the impact of the flowing water in the pool is relatively large, which increases the vibration of the underwater part of the pump. The balance plate gap at the end of the shaft is too large, or the axial working movement is improperly adjusted, which will cause low-frequency movement of the shaft and lead to bearing vibration.
