Gas-Cooling Roots Pump

During decarburization processes the Gas-Cooling Roots Pump china vacuum system must operate very long time in a rough pressure range. An efficient gas-cooling is essential as the extracted sizzling 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 industries have to obtain a particular vacuum environment. At the same time, the vacuum system utilized by these industries is definitely continuously increasing, 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 prevailing dry vacuum pumps on the market, such as for example screw vacuum pumps and claw vacuum pumps, are unable to meet up with the requirements of oil-free large pumping acceleration clean vacuum environment proposed by these industries because of the restrictions of pumping acceleration 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 utilization in a clean vacuum environment with large oil-free pumping speed.
