Vacuum pump in the vacuum system to assume the task
As the performance of various vacuum pumps except to meet the vacuuming of the container to the common point, there are still differences. Therefore, the selection must be clear pump in the vacuum system, the task undertaken by it is very important, pump in a variety of different areas of work to sum up the role of the following major aspects. 1, make the main pump in the system The so-called main pump is the vacuum system is pumping the vacuum container directly to meet the vacuum requirements to meet the technical requirements of the vacuum pump. 2, roughing pump roughing pump refers to the atmospheric pressure began to reduce the pressure of the vacuum system to another suction system can start working vacuum pump. 3, the fore pump The forepump pump is used to maintain the pressure of the previous stage of the other pump at its highest permissible level before the vacuum pump. 4, maintain the pump to maintain the pump means that when the vacuum system is very small, can not effectively use the main pump. To this end, in the vacuum system is also equipped with a lower suction speed auxiliary foreline pump to maintain the normal operation of the main pump or vacuum pump to maintain the vacuum required for the evacuated container. 5, rough vacuum pump or low vacuum pump rough, low vacuum pump is from the beginning of the atmosphere, reducing the pressure is reduced after pumping the container to work in the low vacuum or rough vacuum pressure within the scope of the vacuum pump. 6, high vacuum pump High vacuum pump is the vacuum pump working in the high vacuum range. 7, ultra-high vacuum pump Ultra-high vacuum pump refers to the work in the ultra-high vacuum range of the vacuum pump. 8, booster pump Booster pump usually refers to work between the low vacuum pump and high vacuum pump, to increase the pumping system in the middle of the pressure range of pumping capacity or reduce the requirements of the pump suction pump speed.
