Causes of overheating of multistage pump bearings
1. The multi-stage pump shaft and the motor shaft are out of size when installing or inspecting, causing the bearing to overheat due to vibration.
2. The bearing is damaged, the rotating parts wear and cause vibration to make the bearing overheat.
3. The filler ages, scratching the bushing and generating overheating affects the bearing.
4. Bearing grease lubricant does not match. Too much or too much will cause the bearing to overheat.
5. Bearing transparent oil lubricant added too little or leakage, the bearing should also be overheated.
6. The lubricant in the oil tank deteriorates or enters the water, which can also overheat the bearing.
7. The bearing cooling water is not enough or interrupted, causing the bearing to overheat.
8. Multi-stage pump generates cavitation to make the pump body, bearing overheating, etc.
