Gas-Cooling Roots Pump

During decarburization procedures the vacuum system must operate very long time in a tough pressure range. A competent 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 product quality in aerospace, energy, iron and steel processing, pharmaceutical and chemical industries, these industries need to obtain a specific vacuum environment. At the same time, the vacuum system utilized by these industries is definitely continuously increasing, and the vacuum level is continuously increasing. Furthermore, the state’s environmental security, energy conservation and three wastes discharge to the above-talked about industries, etc. Certain requirements are more stringent. At present, the prevailing dry vacuum pumps on the market, such as screw vacuum pumps and claw vacuum pumps, are unable to meet the requirements of oil-totally free large pumping quickness clean vacuum environment proposed by these industries due to the restrictions of pumping speed characteristics and structural mechanism.

Because of the shortcomings of the prevailing technology, the technical problem to be solved by the utility model is to provide an Gas-Cooling Roots Pump china all-gas-cooled vacuum system to fulfill the use in a clean vacuum environment with large oil-free pumping speed.
