Rotary vane vacuum pump is a common vacuum equipment widely used in scientific research, industry, and manufacturing fields. Its unique working principle and superior performance make it a key tool for achieving high vacuum. This article will introduce the working principle, main characteristics, and applications in different fields of rotary vane vacuum pumps.

operational principle

The rotary vane vacuum pump utilizes rotating blades to generate compressed air in the pump chamber, achieving the suction and discharge of gas. When a closed space is formed between the rotating blades in the pump chamber and the pump chamber wall, the gas is compressed and discharged by centrifugal force. The rotary vane vacuum pump gradually reduces the pressure in the pump chamber through continuous rotation and compression cycles, achieving the required vacuum degree.

main features
