Gas-Cooling Roots Pump

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

With the development of technology and the improvement of product quality in aerospace, electric power, iron and steel processing, pharmaceutical and chemical industries, these Gas-Cooling Roots Pump industries need to obtain a particular vacuum environment. At the same time, the vacuum system used by these industries is definitely continuously raising, and the vacuum degree is continuously increasing. Moreover, the state’s environmental safety, energy saving and three wastes discharge to the above-described industries, etc. The requirements are more stringent. At the moment, the existing 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 rate clean vacuum environment proposed by these industries due to the restrictions of pumping acceleration characteristics and structural system.

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 fulfill the utilization in a clean vacuum environment with large oil-free pumping speed.
