Principle of Roots vacuum pump with direct exhaust
Roots pump uses the internal cooling method, the heat is directly taken away from the heat source by the circulating cooling air, that is, the extracted gas is cooled by the cooling air when it is compressed or discharged, so this kind of pump can be used to regulate the place where the pump can not operate.
The pump cavity can be cooled by itself, because there is a special part of the impeller and working chamber. When this special part works, a part of the working chamber is closed, blocking the inlet and outlet. Through the special vent, the cooling gas flows out from the pressure side or enters the operation cavity again, and then fills with the cooling gas with pressure from the outlet side, and the gas circulates in this way.
The air circulation cooling roots pump is controlled by a special impeller head without additional control elements. Therefore, this kind of internal circulation cooling roots pump is the same as ordinary roots pump, with simple and clean structure. It connects the cooler and the exhaust port together, and the cooler is installed outside the pump shell, which is convenient for repair, maintenance and replacement.
