Gas-Cooling Roots Pump

During decarburization procedures the vacuum system needs to operate long time in a tough pressure range. A competent gas-cooling is necessary as the extracted sizzling gases would otherwise 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 certain vacuum environment. At the same time, the vacuum system used by these industries is continuously raising, and the vacuum degree is continuously increasing. Moreover, the state’s environmental protection, energy conservation and three wastes discharge to the above-described industries, etc. Certain requirements are more stringent. At present, the prevailing dry vacuum pumps out there, such as for example screw vacuum pumps and claw vacuum pumps, cannot meet the requirements of oil-free large pumping quickness clean vacuum environment proposed by these industries because of the restrictions of pumping quickness characteristics and structural mechanism.

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