Gas-Cooling Roots Pump

During decarburization processes the vacuum system needs to operate long time in a rough pressure range. An efficient gas-cooling is necessary as the extracted hot gases would otherwise overheat the filter and vacuum system.

With the development of technology and the improvement of product quality in aerospace, electric power, iron and steel processing, 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 increasing, and the vacuum degree is continuously increasing. Moreover, the state’s environmental protection, energy saving and three wastes discharge to the above-mentioned industries, etc. The requirements are more stringent. At present, the existing dry vacuum pumps on the market, such as screw vacuum pumps and claw vacuum pumps, are unable to meet the requirements of oil-free large pumping speed clean vacuum environment proposed by these industries due to the restrictions of pumping speed 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 provide an all-gas-cooled vacuum system to satisfy the use in a clean vacuum environment with large oil-free pumping speed.
