The vacuum tightness of vacuum pump is affected by many factors, among which the important one is the shaft seal pressure. If the pressure of the shaft seal is too large, the clearance of the pump will be reduced, resulting in the heating of the shaft seal; if the pressure of the shaft seal is too small, it will increase the clearance of the pump, resulting in the excessive leakage of the shaft seal, thus affecting the working efficiency of the pump.
In order to ensure the shaft seal pressure of the pump operation, the steam supply pressure of the shaft seal formed by the self sealing of the low stable combustion load and high load shaft seal system of the pump shall be 45kpa. While meeting the pressure of the low pressure seal shaft seal, the water inflow in the oil shall be reduced, and the water level of the shaft seal heater shall be monitored. If the water level is abnormal, it shall be adjusted in time to remove the situation that there is no water level added to the shaft or the water level is too low, resulting in the drop of vacuum tightness Appear.
The above method is to ensure the vacuum tightness of the vacuum pump. At present, the pump is widely used and has a good development prospect. I hope the above method can help you.
