[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical or physicochemical methods to evacuate the container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain a vacuum in a closed space. A molecular pump is a vacuum pump that uses a high-speed rotating rotor to transfer momentum to gas molecules, so that they obtain a directional speed, are compressed, and are driven to the exhaust port to be evacuated by the front stage.
