Common causes of excessive bearing temperatures
Poor lubrication, such as insufficient lubrication or excessive lubrication, the quality of the lubricant does not meet the requirements, deterioration or debris;
Insufficient cooling, such as blockage of the pipeline, improper selection of the cooler, poor cooling effect
Abnormal bearing, such as bearing damage, poor bearing assembly process, gap adjustment of bearing housing parts does not meet the requirements
The vibration is large, such as the difference in the alignment process of the coupling does not meet the requirements, the rotor has dynamic and static imbalance, the basic rigidity is poor, the ground is virtual, the rotation stalls and the surge.
