Most mechanical vacuum pumps used in the vacuum industry use water, oil or other polymer fluids as the working medium of the pump. With the development of science and technology and the expansion of vacuum pump application, there are two urgent problems to be solved in the original mechanical vacuum pump and its pumping system. One is that the working medium of the pump is polluted by the backflow of the pumping vessel, which in many cases affects the quality and quantity of the product and increases the cost of equipment maintenance. . Secondly, it is difficult to recover the gas pumped into the vacuum pump during some process, and the medium in the pump is deteriorated.
Dry screw oil-free vacuum pump with its compact and simple structure, non-friction of the original pump chamber, long life, low energy consumption, no oil pollution and other advantages, more and more manufacturers favor. It has an incomparable advantage in the chemical industry, and gradually replaced the traditional mechanical vacuum pump. The easy recovery of chemical gas has greatly saved production costs and reduced the environmental pressure of enterprises.
