Gas-Cooling Roots Pump

During decarburization procedures the vacuum system needs to operate very long time in a tough pressure range. An efficient gas-cooling is essential as the extracted sizzling gases would or else overheat the filter and vacuum program.

With the development of technology and the improvement of item quality in aerospace, energy, 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 usually continuously raising, and the vacuum level is continuously increasing. Furthermore, the state’s environmental safety, energy conservation and three wastes discharge to the above-pointed out industries, etc. The requirements are more stringent. At the moment, the existing dry vacuum pumps out there, such as for example screw vacuum pumps and claw vacuum pumps, are unable to meet up with the requirements of oil-totally free large Gas-Cooling Roots Pump pumping swiftness clean vacuum environment proposed by these industries due to the restrictions of pumping swiftness 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 fulfill the use in a clean vacuum environment with huge oil-free pumping speed.
