Gas-Cooling Roots Pump

During decarburization procedures the vacuum system needs to operate long time in a tough pressure range. A competent gas-cooling is necessary as the extracted scorching 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 Gas-Cooling Roots Pump industries have to obtain a particular vacuum environment. Simultaneously, the vacuum system used by these industries is usually continuously increasing, and the vacuum level is continuously increasing. Moreover, the state’s environmental protection, energy conservation and three wastes discharge to the above-stated industries, etc. Certain requirements are more stringent. At present, the prevailing dry vacuum pumps in the marketplace, such as screw vacuum pumps and claw vacuum pumps, cannot meet the requirements of oil-totally free large pumping quickness clean vacuum environment proposed by these industries due to the restrictions of pumping acceleration characteristics and structural system.

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