The Role Of Vacuum Pumps in Different Uses

As the main pump in the system
The so-called main pump is the vacuum pump that directly stops the vacuuming of the pumped container of the vacuum system to meet the vacuum degree required by the process requirements.

 Primitive pump 
A Rough pump refers to a vacuum pump that initially loses the vacuum system pressure from atmospheric pressure to another pumping system that can initially work. 

 A frontline pump 
A foreline pump is a vacuum pump used to keep the foreline pressure of another pump below its foreline pressure. 

 Maintain the pump 
Keeping the pump means that the pumping of the serious empty system is very small, and the important backing pump cannot be used effectively. For this reason, an auxiliary backing pump with a small pumping rate is additionally equipped in the vacuum system to maintain the normal operation of the main pump or a vacuum pump that maintains the high pressure required by the empty container.

 Rough vacuum pump or low vacuum pump
Rough and low vacuum pumps refer to vacuum pumps that start from the atmosphere and work in the field of low vacuum or rough vacuum pressure after losing the pressure of the pumped container. 

Highl vacuum pump 
A high vacuum pump refers to a vacuum pump that works in the high vacuum field. 

Ultra-high vacuum pump
The ultra-high vacuum pump refers to the vacuum pump that works in the ultra-high vacuum field. 

Booster pumps 
The booster pump usually refers to the vacuum pump that works between the low vacuum pump and the high vacuum pump to improve the pumping capacity of the pumping system in the field of central pressure or to reduce the pumping speed of the backing pump.
