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 warm 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 need to obtain a certain vacuum environment. At the same time, the vacuum system used by these industries is definitely continuously raising, and the vacuum degree is continuously increasing. Furthermore, the state’s environmental security, energy conservation and three wastes discharge to the above-mentioned industries, etc. The requirements are more stringent. At present, the prevailing dry vacuum pumps available, such as for example screw vacuum pumps and claw vacuum pumps, are unable to meet the requirements of oil-totally free large pumping quickness clean vacuum environment proposed by these industries due to the restrictions of pumping swiftness characteristics and structural mechanism.

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