Different vacuum pump in the vacuum system of the role of different _ constant mechanical and electrical equipment co. , LTD

due to the different types of vacuum pump can satisfy the vacuum container in common, so still exist differences. Therefore, must choose explicitly in the vacuum pump system, undertake the task of is very important, role in the field of each pump work can be summarized as the following respects.

1, the system of the main pump

the main pump is a vacuum pump, it is necessary for obtaining direct emptying of the vacuum system to meet the technological requirements of vacuum.

2, rough pumping

coarse suction pump is a vacuum pump, it starts from atmospheric pressure to reduce the pressure of the vacuum system, until another pump system began to work.

3, backing pump

before the pump is used to keep level before another pump pressure before its maximum allowable level under the pressure of vacuum pump.

4, maintain pumps

in order to maintain the pump, this means that when the suction of the vacuum system is very small, cannot get effective use of pump before the Lord. Therefore, also set up in the vacuum system has lower pumping speed of the auxiliary pump before, in order to maintain the normal operation of the main pump or maintain emptying containers required for low pressure vacuum pump.

5, rough vacuum pump or low vacuum pump

coarse vacuum pump starts and reduce atmospheric vacuum pump pumping pressure container, in the low vacuum or coarse vacuum pressure within the scope of work.

6, high vacuum pumps

high vacuum pump is a vacuum pump running in high vacuum range.

7, ultra high vacuum pumps

ultra-high vacuum pump is within the scope of the ultra high vacuum of vacuum pump operation. 8, the booster pump

booster pump is a vacuum pump, usually run between the low vacuum and high vacuum pump, in order to increase the pumping capacity of pump system is within the scope of medium voltage or lower backing pump pumping speed.
