What is the difference between the individual bearing temperature rise and the general increase in bearing temperature? 2020-03-26


The cause of the temperature rise of individual bearings: ⑴ Increased load, uneven bearing force distribution, and individual bearing load.  Poor oil or oil return. (3) Debris in the bearing and hulling.  Excessive steam leakage or leakage from the shaft seal on the bearing side. There is gas in the bearing and the oil flow is not smooth.  Vibration causes oil film damage and poor lubrication. Reasons for the general increase in bearing temperature:  The oil outlet temperature of the oil cooler has increased due to some reasons. ⑵Oil quality deteriorates.
