Gas-Cooling Roots Pump

During decarburization procedures the vacuum system must operate long time in a rough pressure range. An efficient gas-cooling is essential as the extracted sizzling gases would Gas-Cooling Roots Pump otherwise overheat the filter and vacuum system.

With the development of technology and the improvement of item quality in aerospace, energy, iron and steel processing, pharmaceutical and chemical industries, these industries have to obtain a particular vacuum environment. At the same time, the vacuum system utilized by these industries can be continuously increasing, and the vacuum level is continuously increasing. Furthermore, the state’s environmental safety, energy conservation and three wastes discharge to the above-talked about industries, etc. Certain requirements are more stringent. At the moment, the existing dry vacuum pumps on the market, such as for example screw vacuum pumps and claw vacuum pumps, are unable to meet the requirements of oil-totally free large pumping velocity clean vacuum environment proposed by these industries because of the restrictions of pumping velocity characteristics and structural mechanism.

Because of the shortcomings of the prevailing technology, the specialized problem to be solved by the 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.
