What are the classifications of mechanical vacuum pumps

Vacuum pump is a device which can produce, improve and maintain vacuum in a closed space by various methods. Vacuum pump can be defined as a device or equipment that uses mechanical, physical, chemical or physical chemical methods to extract air from the container to obtain vacuum. With the development of vacuum application, there are many kinds of vacuum pumps, whose pumping speed is from 0.5 liter per second to hundreds of thousands and millions of liters per second. Limit pressure (limit vacuum) ranges from coarse vacuum to ultra-high vacuum above 10-12pa.

Due to the wide range of working pressure involved in the vacuum application department, it is impossible for any type of vacuum pump to be fully applicable to all working pressure ranges. Different types of vacuum pumps can only be used according to different working pressure ranges and different working requirements.

In order to use conveniently and meet the needs of various vacuum processes, various vacuum pumps are sometimes combined according to their performance requirements and applied in the form of units. A pump that uses mechanical movement (rotation or sliding) to obtain vacuum is called a mechanical vacuum pump. According to its working principle and structural characteristics, mechanical vacuum pump is described as follows:

Variable volume vacuum pump is a vacuum pump which uses the periodic change of the volume of the pump cavity to complete suction and exhaust to achieve the purpose of suction. The gas is compressed before being discharged from the pump chamber. This kind of pump is divided into reciprocating type and rotary type.
