Due to the high speed of the vacuum pump in the case of a high speed rotor, the rotor supporting the rotor heats up. Then the vacuum pump bearing heat is caused by the above, what are the solutions? 1. Cracking of the valve plate: When a valve plate cracks, the pressure on both sides of the impeller will be unbalanced, and the axial force will occur in the rotor, which will intensify the bearing load. The long-term operation will increase the bearing temperature. In this case, replace the valve plate in time. 2. Shaft end seal failure: When the shaft end seal packing root is damaged or the seal water hole is blocked, air will be drawn into the pump body from these damaged cracks, which will lead to pump suction and exhaust performance. If only one side of the seal fails, it will form imbalance on both sides of the impeller pressure, the axial force of the rotor, the bearing load increases, so that the bearing temperature increases. 3. The bearing pre-tightening force is too large: This situation will promote the reduction of bearing clearance or no play, resulting in bearing warming. 4. Vibration effect: When the pump body or bearing sensation is large, the bearing temperature will be too high. Check the pump body to find the cause of the vibration and eliminate the vibration, then the bearing temperature will recover. 5.Smooth phenomenon: The increase in the amount of smooth grease is too large or too small, or the type of smooth grease does not meet, and its use time is too long. If the grease is contaminated, the bearing will generate heat. Assassin, you should check the type of smooth grease, ask the manufacturer for the appropriate amount, adjust the smooth grease to restore the bearing temperature. 6. Bearing damage: bearing overturning and bearing cage damage will be accompanied by bearing overheating phenomenon. Damage to the bearings necessitates the timely replacement of new bearings.
