Rotary vane vacuum pump is a common type of vacuum pump that uses rotating blades or blades to create vacuum. The following are the working principles and some common uses of rotary vane vacuum pumps:

Working principle:

Rotary vane structure: The rotary vane vacuum pump consists of a rotary vane (also known as a rotary vane) and an elliptical fixed shell. The rotating blade is located inside the shell and maintains contact with it.

Rotating disc: When the vacuum pump is started, the disc begins to rotate at high speed. Usually, the rotor is driven by an electric motor or other driving device.

Centrifugal force: The rotation of the rotating disc generates centrifugal force within the fixed shell. Due to the shape of the rotating blade, centrifugal force will suck in gas from the inlet and exhaust it outward.

Vacuum creation: When gases enter the pump, they are brought into the exhaust port by the motion of the rotating blades. This process leads to a continuous pumping process of gas from the inlet to the exhaust port, creating a vacuum.

Purpose:

Laboratory applications: Rotary vane vacuum pumps are often used in laboratory environments to prepare high vacuum or high vacuum conditions for experiments, analysis, and testing. They are suitable for vacuum systems of mass spectrometers, electron microscopes, spectrometers, and other laboratory instruments.

Semiconductor manufacturing: Rotary vane vacuum pumps are used in the semiconductor industry for cleaning, deposition, etching, and film preparation processes. These applications typically require a very clean vacuum environment.

Medical equipment: In the manufacturing of medical equipment, rotary vane vacuum pumps are used for vacuum encapsulation and processing, such as vacuum systems for preparing X-ray tubes or electron microscopes.

Chemical industry: Rotary vane vacuum pumps are used in the chemical industry for separation, distillation, and drying processes. They can be used to process chemicals and solutions while ensuring high purity and high vacuum.

Food packaging: In the field of food packaging, rotary vane vacuum pumps are used to prepare vacuum sealed packaging to extend the shelf life of food.

Aerospace: Rotary vane vacuum pumps are equipment used in the aerospace field to simulate space conditions and test spacecraft.
