Gas-Cooling Roots Pump

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

With the development of technology and the improvement of item quality in aerospace, electric power, iron and steel processing, pharmaceutical and chemical industries, these industries have to obtain a Gas-Cooling Roots Pump china specific vacuum environment. At the same time, the vacuum system utilized by these industries is continuously raising, and the vacuum level is continuously increasing. Moreover, the state’s environmental safety, energy conservation and three wastes discharge to the above-described industries, etc. Certain requirements are more stringent. At present, the existing dry vacuum pumps in the marketplace, such as for example screw vacuum pumps and claw vacuum pumps, are unable to meet the requirements of oil-free large pumping acceleration clean vacuum environment proposed by these industries because of the restrictions of pumping rate characteristics and structural system.

In view 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 satisfy the utilization in a clean vacuum environment with large oil-free pumping speed.
