Gas-Cooling Roots Pump

During decarburization processes the vacuum system must operate very long time in a rough pressure range. An efficient 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 certain vacuum environment. Simultaneously, the vacuum system utilized by these industries is continuously raising, and the vacuum level is continuously increasing. Furthermore, the state’s environmental security, energy saving and three wastes discharge to the above-described industries, etc. The requirements are more stringent. At present, the existing dry vacuum pumps out there, such as screw vacuum pumps and claw vacuum pumps, Gas-Cooling Roots Pump cannot meet up with the requirements of oil-totally free large pumping quickness clean vacuum environment proposed by these industries because of the restrictions of pumping speed characteristics and structural mechanism.

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