What is a vacuum pump? The vacuum pumps are a rotary variable displacement vacuum pump that must be used with a foreline pump. It has a large pumping speed over a wide pressure range and is insensitive to dust and water vapor in the extracted gas. It is widely used. Metallurgy, chemical, food, electronic coating, and other industries.
Vacuum pump features
(1) Large pumping speed over a wide range of pressures;
(2) The compression is relatively low, and the effect on hydrogen gas pumping is poor;
(3) There is no compression in the pump chamber, no exhaust valve.
(4) 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 rotation speed;

At present, vacuum pumps have been widely used in metallurgy, chemical, food, electronic coating, and other industries. Therefore, the quality of the vacuum pump determines the development of our metallurgical, chemical and other industries, then we need to pay attention to some related matters when using the vacuum pump, and protect it to the maximum extent.
If the volatile organic solvent is distilled, the organic solvent is absorbed by the oil, which increases the vapor pressure, thereby reducing the evacuation efficiency. If it is water vapor, the oil becomes an emulsion and the vacuum pump is pumped.
