Gas-Cooling Roots Pump

During decarburization procedures the vacuum system must operate long time in a rough pressure range. An efficient gas-cooling is essential as the extracted hot gases would otherwise overheat the filter and vacuum system.

With the development of technology and the improvement of item quality in aerospace, energy, iron and steel processing, Gas-Cooling Roots Pump china pharmaceutical and chemical industries, these industries have to obtain a certain vacuum environment. At the same time, the vacuum system utilized by these industries is usually continuously increasing, and the vacuum level is continuously increasing. Moreover, the state’s environmental safety, energy conservation and three wastes discharge to the above-stated industries, etc. The requirements are more stringent. At the moment, the existing dry vacuum pumps on the market, such as for example screw vacuum pumps and claw vacuum pumps, cannot meet the requirements of oil-totally free large pumping quickness clean vacuum environment proposed by these industries because of the restrictions of pumping speed characteristics and structural mechanism.

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.
