All kinds of centrifugal pumps have bearing parts. Bearing is also a high-speed rotating component, so it is easy to appear the phenomenon of centrifugal pump bearing heating. What are the reasons for the heating of centrifugal pump bearings? Causes of the centrifugal pump bearing heating is mainly due to the centrifugal pump in use in the process of working with low head centrifugal pump head is relatively high, this condition can easily lead to the outlet of the centrifugal pump the water beyond the actual numerical rated flow of centrifugal pump, so that the motor current exceeds the rated current of the centrifugal pump, the motor exceeds the current after the motor will be hot after the motor temperature rise due to the high temperature bearing oil will lead to loss of bearing oil, bearing oil flow bearing wear will be blocked.

The centrifugal pump product connected by coupling is caused by the reason that the pump shaft of centrifugal pump is bent or the center of the coupling does not adjust well, which results in the bearing heating of the centrifugal pump. It is also possible that the length of the bearing is too long to add grease to the bearing, which is also the cause of the heating of the centrifugal pump bearing.
