Gas-Cooling Roots Pump

During decarburization processes the vacuum system needs to 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 item quality in aerospace, electric power, iron and steel digesting, pharmaceutical and chemical industries, these industries have to obtain a certain vacuum environment. Simultaneously, the vacuum system utilized by these industries is usually continuously raising, and the vacuum degree is continuously Gas-Cooling Roots Pump increasing. Moreover, the state’s environmental protection, energy saving and three wastes discharge to the above-talked about industries, etc. Certain requirements are more stringent. At the moment, the prevailing dry vacuum pumps available, such as for example screw vacuum pumps and claw vacuum pumps, are unable to meet the requirements of oil-free large pumping speed clean vacuum environment proposed by these industries because of the restrictions of pumping swiftness characteristics and structural system.

In view of the shortcomings of the existing technology, the technical 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 large oil-free pumping speed.
