Gas-Cooling Roots Pump

During decarburization processes the vacuum system needs to operate long time in a rough pressure range. An efficient gas-cooling is necessary as the extracted 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 china industries need to obtain a particular vacuum environment. At the same time, the vacuum system utilized by these industries is usually continuously raising, and the vacuum level is continuously increasing. Furthermore, the state’s environmental protection, energy conservation and three wastes discharge to the above-described industries, etc. The requirements are more stringent. At the moment, the prevailing dry vacuum pumps in the marketplace, such as screw vacuum pumps and claw vacuum pumps, are unable to meet up with the requirements of oil-free large pumping quickness clean vacuum environment proposed by these industries due to the restrictions of pumping rate characteristics and structural mechanism.

In view of the shortcomings of the existing technology, the technical problem to be solved by the utility model is to supply an all-gas-cooled vacuum system to satisfy the use in a clean vacuum environment with large oil-free pumping speed.
