In the selection of dry vacuum pump, it is very important to make clear the work task of the pump in the vacuum system. Therefore, the role of the vacuum pump in the vacuum system is mainly reflected in the following aspects:
1. Rough pumping pump
The production of crude pumping pump is from atmospheric pressure to reduce the vacuum system pressure to another pumping system can start to work
2. Main pump in the system
The so-called main pump is directly vacuum the vacuum system is pumped container to obtain the vacuum required to meet the requirements of the process.
3. Maintain the pump
The production of the maintenance pump is identified as the vacuum system pumping is very small, can not effectively use the main pre pump. For this purpose, an auxiliary front stage pump with a lower pumping speed is provided in the vacuum system to maintain the normal operation of the main pump or maintain the low pressure required for the evacuated container.
Dry vacuum pump
4, coarse and low vacuum pump, refers to the atmosphere from the start, reduce the pressure of the container to work in the low vacuum or rough vacuum pressure range.
5. Front stage pump
The production of the forepump is used to maintain the pressure of another pump in the forestage below its maximum permitted pressure.
6, high vacuum pump, refers to the work in the high vacuum range.
7, ultra high vacuum pump, refers to the work in the ultra high vacuum range.
8, booster pump, usually refers to the work between high and low vacuum pump, in order to improve the pumping system in the middle pressure range or reduce the pumping rate of the front stage pump requirements.
Only by understanding the role of the vacuum pump in the vacuum system, a thorough understanding of a piece of equipment, in order to facilitate future use.
