Common causes of excessive bearing temperature

1) such as insufficient lubrication or excessive lubrication, lubricating oil quality does not meet the requirements, deterioration or debris;

2) insufficient cooling, such as pipeline blockage.

3) The bearing is abnormal, such as bearing damage, poor bearing assembly process, and the clearance adjustment of each part of the bearing box does not meet the requirements;

4) Large vibration, such as poor alignment process of the coupling does not meet the requirements, dynamic and static imbalance of the rotor, poor foundation rigidity, virtual foundation, rotating stall and surge.
