Roots vacuum pump is a new product developed by our company on the basis of accumulated years of manufacturing experience. It is characterized by:
Fast start-up, low power consumption, low operation and maintenance cost, high pumping speed, high efficiency, insensitive to a small amount of water vapor and dust contained in the pumped gas, and a large pumping rate in the pressure range of 100 to 1 Pa. Can quickly eliminate the sudden release of gas.
(1) 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. Roots vacuum pumps have developed rapidly in recent years at home and abroad. It has been widely used in smelting, petrochemical, electrician, electronics and other industries.
Roots vacuum pumps are widely used in smelting, degassing, rolling in vacuum metallurgy, as well as vacuum distillation, vacuum concentration and vacuum drying in the chemical, food and pharmaceutical industries.
