Vacuum Pump

Vacuum Pump refers to a device or device that uses mechanical, physical, chemical, or physicochemical methods to evacuate a pumped container to obtain a vacuum. In general, a vacuum pump is a device that uses various methods to improve, create, and maintain a vacuum in an enclosed space.
According to the working principle of the vacuum pump, the vacuum pump can basically be divided into two types, namely, a gas trap pump and a gas transfer pump. It is widely used in metallurgy, chemical, food, electronic coating and other industries.
Features
(1) There is a large pumping speed over a wide pressure range;
(2) The rotor has good geometric symmetry, so the vibration is small and the operation is stable. There is a gap between the rotor and between the rotor and the casing, no lubrication, and the friction loss is small, which can greatly reduce the driving power, thereby achieving a higher rotational speed;
(3) Oil seal and lubrication are not required in the pump chamber, which can reduce the pollution of the vacuum system by oil vapor;
(4) There is no compression in the pump chamber, no exhaust valve. The structure is simple and compact, and is insensitive to dust and water vapor in the pumped gas;
(5) The compression is relatively low, and the effect on hydrogen gas pumping is poor;
(6) The surface of the rotor is a curved cylinder with a complicated shape, which is difficult to process and inspect.
