Vacuum pump in vacuum system

When selecting the vacuum pump, we must make clear the work tasks of the vacuum pump in the vacuum system, and the role of the vacuum pump in various work fields. EVP vacuum pump manufacturers can sum up the following aspects.

1. Be the main pump in the system

The so-called main pump is a vacuum pump which directly vacuumizes the vacuum system to obtain the vacuum degree required by the process requirements.

2. Crude pump

Crude pumping pump is a kind of pump that starts from atmospheric pressure to reduce the pressure of vacuum system to another pumping system.

3. Front stage pump

The front stage pump is used to keep the pressure of another pump below its maximum allowable pressure.

4. Maintenance pump

Maintenance pump refers to that when the vacuum system is very small, the main front stage pump can not be effectively used. In order to maintain the normal operation of the main pump or to maintain the low pressure vacuum pump required by the evacuated container, another auxiliary front stage pump with low pumping speed is equipped in the vacuum system.

5. Crude or low pump

Crude and low pump is a kind of pump which starts from the atmosphere and works in the range of low vacuum or rough vacuum pressure after reducing the pressure of the pumped vessel.

6. High pump

High pump refers to the pump working in the high vacuum range.

7. Super high pump

Ultra high pump refers to the pump working in the ultra-high vacuum range.

8. Booster pump

Booster pump usually refers to the vacuum pump which works between low pump and high pump to improve the air pumping volume of the pumping system in the middle pressure range or to reduce the requirement of the pumping rate of the previous stage pump.

Through the above introduction, it can be seen that in the vacuum system, the vacuum pump is essential, and the items it has to undertake can not be ignored.
