Gas-Cooling Roots Pump

During decarburization procedures the vacuum Gas-Cooling Roots Pump china system must operate very long time in a rough pressure range. A competent gas-cooling is necessary as the extracted hot 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 digesting, pharmaceutical and chemical industries, these industries need to obtain a specific vacuum environment. Simultaneously, the vacuum system utilized by these industries is usually continuously increasing, and the vacuum level is continuously increasing. Moreover, the state’s environmental protection, energy conservation and three wastes discharge to the above-pointed out industries, etc. Certain requirements are more stringent. At present, the prevailing dry vacuum pumps on the market, such as for example screw vacuum pumps and claw vacuum pumps, cannot meet up with the requirements of oil-free large pumping swiftness clean vacuum environment proposed by these industries due to the restrictions of pumping quickness characteristics and structural mechanism.

In view of the shortcomings of the existing technology, the technical problem to be solved by the utility model is to supply an all-gas-cooled vacuum system to fulfill the use in a clean vacuum environment with large oil-free pumping speed.
