Gas-Cooling Roots Pump

During decarburization processes the vacuum system must operate long time in a tough Gas-Cooling Roots Pump china pressure range. A competent gas-cooling is necessary as the extracted sizzling gases would or else overheat the filter and vacuum system.

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 particular vacuum environment. Simultaneously, the vacuum system utilized by these industries is definitely continuously raising, and the vacuum level is continuously increasing. Moreover, the state’s environmental security, energy saving and three wastes discharge to the above-talked about industries, etc. The requirements are more stringent. At the moment, the existing dry vacuum pumps in the marketplace, such as screw vacuum pumps and claw vacuum pumps, cannot meet the requirements of oil-totally free large pumping acceleration clean vacuum environment proposed by these industries because of the restrictions of pumping swiftness characteristics and structural system.

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