The task of the vacuum pump in the vacuum system
There are differences in the performance of various vacuum pumps, in addition to meeting the commonality of vacuuming containers. Therefore, it is very important to clarify the tasks that the pump undertakes in the vacuum system when selecting. The functions of the pump in various work fields are summarized as follows.
1, the main pump in the system
The so-called main pump is a vacuum pump that directly vacuums the vacuum system to obtain the vacuum required to meet the process requirements.
2, rough pump
The rough pump refers to a vacuum pump that starts to reduce the pressure of the vacuum system from atmospheric pressure until another pumping system can start working.
3. Foreline pump
The foreline pump refers to a vacuum pump used to maintain the pressure of the front stage of another pump below its highest permissible pre-stage pressure.
4, maintain the pump
Maintaining the pump means that when the vacuum system draws very little, the main foreline pump cannot be effectively utilized. To this end, an auxiliary fore pump with a lower pumping speed is additionally provided in the vacuum system to maintain the normal operation of the main pump or to maintain the low pressure vacuum pump required for the evacuated container.
5, rough vacuum pump or low vacuum pump
The coarse and low vacuum pump refers to a vacuum pump that starts from the atmosphere and reduces the pressure of the pumped container and operates in a low vacuum or rough vacuum pressure range.
6, high vacuum pump
A high vacuum pump is a vacuum pump that operates in a high vacuum range.
7, ultra high vacuum pump
Ultra-high vacuum pumps are vacuum pumps that operate in the ultra-high vacuum range.
8, booster pump
A booster pump is generally referred to as a vacuum pump that operates between a low vacuum pump and a high vacuum pump to increase the pumping capacity of the pumping system in the intermediate pressure range or to reduce the pumping rate of the foreline pump.
