Shanghai Yetuo 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 levels. This article will introduce the working principle, main characteristics, and applications of rotary vane vacuum pumps in different fields.

working principle

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

main features 

High vacuum degree: Rotary vane vacuum pumps can provide a high vacuum degree, usually ranging from tens to hundreds of pascals, suitable for various vacuum applications.

High performance: The rotary vane vacuum pump has a high pumping speed and low pump speed limit, which can quickly extract gas and achieve low residual gas pressure.

Strong reliability: The rotary vane vacuum pump adopts excellent materials and precision manufacturing processes, with high durability and stability, and can operate stably for a long time.

Low noise and vibration: The rotary vane vacuum pump is designed to be compact, with low levels of noise and vibration, reducing the impact on the working environment and operators.
