Gas-Cooling Roots Pump

During decarburization processes the vacuum system must operate very long time in a rough pressure range. A competent gas-cooling is necessary as the extracted sizzling gases would or else overheat the filter and vacuum system.

With the development of technology and the improvement of product quality in aerospace, energy, iron and steel digesting, pharmaceutical and chemical industries, these industries need to obtain a specific vacuum environment. Simultaneously, the vacuum system used by these industries can be continuously raising, and the vacuum degree is continuously increasing. Furthermore, the state’s environmental protection, energy conservation and three wastes discharge to the above-talked about industries, etc. The requirements are more stringent. At the moment, the existing dry vacuum pumps on the market, such as screw vacuum pumps and claw vacuum pumps, are unable to meet up with the requirements of oil-free large pumping acceleration clean vacuum environment proposed by these industries because of the restrictions of pumping rate Gas-Cooling Roots Pump china characteristics and structural system.

Because of the shortcomings of the existing technology, the specialized problem to be solved by the utility model is to provide an all-gas-cooled vacuum system to fulfill the use in a clean vacuum environment with huge oil-free pumping speed.
