The role of vacuum pump in the vacuum system

due to years of experience accumulation and continuous breakthroughs in technology research and development, the performance of these vacuum pumps is different except that they can meet the common point of vacuumizing containers. Therefore, it is very important to clarify the work task of the pump in the vacuum system when selecting. The role of the pump in various work fields can be used in the leather pipe after Lubrizol publicizes the material, mainly in the following aspects

1. Be the main pump in the system

the so-called one pump in the National 863 project is a vacuum pump that directly vacuumizes the evacuated container of the vacuum system to obtain the vacuum degree required to meet the process requirements

2. Rough pumping pump

rough pumping pump refers to a vacuum pump that reduces the pressure of the vacuum system from the atmospheric pressure to the point that another pumping system can start working

3. Front stage pump

front stage pump refers to a vacuum pump used to maintain the front stage pressure of another pump below its maximum allowable elastic deformation - reversible, Hooke's law

4. Maintenance pump

maintenance pump means that the main front stage pump cannot be effectively used when the vacuum system is very small. For this reason, another auxiliary front stage pump with low air extraction speed is equipped in the vacuum system to maintain the normal operation of the main pump or maintain the low-pressure vacuum pump required by the evacuated container

5. Coarse vacuum pump or low vacuum pump

coarse and low vacuum pump refers to the vacuum pump that starts from the atmosphere and works within the range of low vacuum or coarse vacuum pressure after reducing the pressure of the pumped container

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

booster pump usually refers to a vacuum pump that works between a low vacuum pump and a high vacuum pump to increase the air extraction volume of the air extraction system in the middle pressure range or reduce the requirements for the air extraction rate of the previous pump. (end)
