The Role of Vacuum Pump in Vacuum System
Because the performance of all kinds of vacuum pumps can meet the common points of vacuum pumping for containers, there are still differences. Therefore, when choosing the pump, it must be clear about the task of the pump in the vacuum system.
The role of pumps in various fields of work can be summarized as follows:
1. main pump
The so-called main pump is a vacuum pump which directly evacuates the vacuum vessel of the vacuum system in order to obtain the vacuum required to meet the technological requirements.
2. rough pump
Coarse pumping refers to a vacuum pump that reduces the pressure of the vacuum system from atmospheric pressure to another pumping system that can start working.
3. front stage pump
The front stage pump is a vacuum pump used to maintain the front stage pressure of another pump below its z* high permissible front stage pressure.
4. maintenance pump
Maintenance pump means that when the vacuum system pumps very little, it can not effectively use the main front pump. In order to maintain the normal operation of the main pump or the low-pressure vacuum pump needed to maintain the emptied container, an auxiliary front-stage pump with a lower pumping speed is added to the vacuum system.
5. Coarse or Low Vacuum Pumps
Coarse and low vacuum pumps are vacuum pumps that work in the range of low vacuum or rough vacuum pressure after reducing the pressure of the pumped container from the atmosphere.
6. High Vacuum Pump
High vacuum pump refers to the vacuum pump working in the high vacuum range.
7. Ultra High Vacuum Pump
Ultra-high vacuum pump refers to the vacuum pump working in the ultra-high vacuum range.
8. booster pump
Supercharging pump usually refers to a vacuum pump working between a low vacuum pump and a high vacuum pump to increase the pumping capacity of the pumping system in the middle pressure range or to reduce the pumping rate requirements of the front pump.
