Gas-Cooling Roots Pump

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

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 need to obtain a certain vacuum environment. Simultaneously, the vacuum system used by these industries is definitely continuously increasing, and the vacuum level is continuously increasing. Furthermore, the state’s environmental protection, energy conservation and three wastes discharge to the Gas-Cooling Roots Pump china above-mentioned industries, etc. Certain requirements are more stringent. At the moment, the existing dry vacuum pumps in the marketplace, such as for example screw vacuum pumps and claw vacuum pumps, are unable to meet up with the requirements of oil-free large pumping rate clean vacuum environment proposed by these industries due to the restrictions of pumping quickness characteristics and structural system.

Because of the shortcomings of the prevailing technology, the technical problem to be solved by the utility model is to provide an all-gas-cooled vacuum system to satisfy the utilization in a clean vacuum environment with huge oil-free pumping speed.
