What are the causes of excessive bearing temperature?
Excessively high bearing temperature is a common and harmful fault in rotating equipment, which will reduce the service life of the bearing and increase maintenance costs. Great impact on economic benefits. Therefore, quickly judging the cause of the failure and taking appropriate measures to solve it is the guarantee for the continuous and safe operation of the equipment.
Common causes of excessive bearing temperature
1) Poor lubrication, such as insufficient lubrication or excessive lubrication, the quality of lubricating oil does not meet the requirements, deterioration or debris;
2) The cooling is not enough, such as the pipeline is blocked, the cooler is not selected properly, and the cooling effect is poor;
3) The bearing is abnormal, such as bearing damage, poor bearing assembly process, and the clearance adjustment of various parts of the bearing box does not meet the requirements;
4) The vibration is large, such as the poor alignment process of the coupling does not meet the requirements, the rotor has dynamic and static imbalances, the foundation rigidity is poor, the ground is weak, the rotation stalls and surges.
