Gas-Cooling Roots Pump

During decarburization processes the vacuum system needs to operate very long time in a rough pressure range. A competent gas-cooling is essential as the extracted scorching gases would or else 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 have to obtain a particular vacuum environment. Simultaneously, the vacuum system utilized by these industries is definitely continuously raising, and the vacuum degree is continuously increasing. Furthermore, the state’s environmental security, energy saving and three wastes discharge to the above-pointed out industries, etc. Certain requirements are more stringent. At present, the existing dry vacuum pumps out there, such as screw vacuum pumps and claw vacuum pumps, cannot meet the requirements of oil-free large pumping quickness clean vacuum environment proposed by these industries Gas-Cooling Roots Pump because of the restrictions of pumping swiftness characteristics and structural system.

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