Gas-Cooling Roots Pump

During decarburization processes the vacuum system must operate very long time in a tough pressure range. A competent gas-cooling is essential as the extracted sizzling gases would otherwise overheat the filter and vacuum system.

With the development of technology and the improvement of item quality in aerospace, electric power, iron and steel processing, pharmaceutical and chemical industries, these industries need to obtain a particular vacuum environment. Simultaneously, the vacuum system used by these industries is certainly continuously Gas-Cooling Roots Pump china increasing, and the vacuum degree is continuously increasing. Furthermore, the state’s environmental security, energy saving and three wastes discharge to the above-talked about industries, etc. Certain requirements are more stringent. At present, the prevailing dry vacuum pumps available, such as for example screw vacuum pumps and claw vacuum pumps, cannot meet the requirements of oil-free large pumping acceleration clean vacuum environment proposed by these industries due to the restrictions of pumping velocity characteristics and structural system.

In view of the shortcomings of the prevailing 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 huge oil-free pumping speed.
