Vacuum pump in the vacuum system to assume the task

As the performance of various vacuum pumps except to meet the vacuuming of the container to the common point, there are still differences. Therefore, the selection must be clear pump in the vacuum system, the task undertaken by it is very important, pump in a variety of different areas of work to sum up the role of the following major aspects.

1, the main pump in the system

The so-called main pump is the vacuum system is pumping the container directly to the vacuum, in order to obtain the vacuum required to meet the process requirements of the vacuum pump.

2, rough pumping

The roughing pump is a vacuum pump that starts to reduce the pressure of the vacuum system from atmospheric pressure to the point where another suction system can start working.

3, before the pump

The foreline pump is the vacuum pump used to maintain the foreline pressure of the other pump below its highest permissible foreline pressure.

4, to maintain the pump

Maintaining the pump means that the main foreline pump can not be used effectively when the pumping of the vacuum system is small. To this end, in the vacuum system is also equipped with a lower suction speed auxiliary foreline pump to maintain the normal operation of the main pump or vacuum pump to maintain the vacuum required for the evacuated container.

5, rough vacuum pump or low vacuum pump

Coarse, low vacuum pump is from the beginning of the atmosphere, reducing the pressure is pumping the container to work in the low vacuum or rough vacuum pressure range of the vacuum pump.

6, high vacuum pump

High vacuum pump is the vacuum pump working in the high vacuum range.

7, high vacuum pump

Ultra-high vacuum pump is to work in the ultra-high vacuum range of vacuum pumps.

8, booster pump

A booster pump generally refers to a vacuum pump that operates between a low vacuum pump and a high vacuum pump to increase the amount of pump suction in the mid-pressure range or to reduce the pumping rate of the foreline pump.
