Roots vacuum pump is characterized by: quick start, less power consumption, low operation and maintenance costs, pumping speed, high efficiency, to be pumped gas contained in a small amount of steam and dust is not sensitive, in the range of 100 ~ 1 pa pressure has a large pumping rate, can quickly exclude the sudden release of air. Widely used in petroleum, chemical, metallurgy, textile, paper making and other industries.Roots vacuum pump is also known as the mechnical booster which is a positive displacement type pump. It is one of the special pumps which can reach middle, high vacuum rang. Its work principle is similar to the Root fan.Both of them used a pair of rotors, whose shape looks like 8, to achieve the suction and discharge process.
This pressure range is between mechanical vacuum pump and diffusion pump oil seal type.Therefore, it is often in series between the diffusion pump and oil seal type vacuum pump, used to improve the swept volume middle pressure range.At this time it is also known as mechanical booster pump.Roots vacuum pump is widely used in the vacuum metallurgy in refining, degassing and rolling, as well as the chemical industry, food, pharmaceutical industry in the vacuum distillation,vacuum concentration and vacuum drying, etc.Vacuum pump parts for vacuum pump noise control, vacuum pump silencer.
