Why is water pump bearing temperature too high

Water pump bearings manufacturer to share with you why water pump bearing temperature is too high, then we'll take a look at what's the reason? The first may be the pump rotor static balance is not good. Pump rotor radial force increases, bearing load, bearing heating. The second pump vibration at the design point operation, also can make water pump bearing heating. Third water pump shaft bending or different heart, can make the water pump bearing heating induced vibration or wear. The fourth bearing fit clearance is not in conformity with the requirements. Such as bearing inner ring and the pump shaft, bearing outer ring and bearing body, too loose or too tight, can cause bearing heating. （ Fit too tight will make bearing rotation is not flexible; Fit is too loose, can make the bearing inner ring rotate or the whole bearing in the bearing) 。 Due to water pump bearing axial thrust increase (5 Such as the water pump in the balance when any serious damage and balance ring) , so that the bearing axial load increase, lead to bearing heating and even damaged. Bearing lubricating oil (6 Fat) Or inadequate or excessive amount, the quality is bad, with sand, iron and other sundry; Sliding bearing for oil ring does not rotate, sometimes not caused by bearing heating oil. Bearing has been damaged (7 Including purchase bearing itself quality problems) , often is a common reason for bearing heating, such as damage of rolling bearing cage, ball crushing inner ring or outer ring fracture; Sliding bearing alloy layer peeling of impellers, etc. This bearing abnormal sound, the noise is big, should be timely open check and replacement of the bearing. Above all, we should be in the usual use process, will watch, and find out the reason in time, and convenient processing.
