Gas-Cooling Roots Pump

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

With the development of technology and the improvement of item quality in aerospace, energy, iron and steel digesting, pharmaceutical and chemical industries, these industries need to obtain a specific vacuum environment. At the same time, the vacuum system used by these industries is certainly continuously increasing, and the vacuum level is continuously increasing. Furthermore, the state’s environmental protection, energy saving and three wastes discharge to the above-mentioned industries, etc. Certain requirements are more stringent. At the moment, the existing dry vacuum pumps on the market, such as for example screw vacuum pumps and claw vacuum pumps, are unable to meet the requirements of oil-free large Gas-Cooling Roots Pump china pumping velocity clean vacuum environment proposed by these industries because of the restrictions of pumping quickness characteristics and structural mechanism.

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