Jiangsu Weigu fluid sharing: The role of screw vacuum pump and the principle of detailed explanation 

 Screw vacuum pump is a kind of equipment that uses a bunch of screws to produce suction at high speed to achieve exhaust effect, which can effectively eliminate water vapor and dust, and has important applications in medicine, chemical industry and other fields. 

The working principle of screw vacuum pump: The working process of the screw vacuum pump can be divided into three processes: suction, compression and exhaust. When the rotor rotates, each pair of teeth meshing with each other completes the same working cycle again. Now, a pair of teeth is used for illustration. Suction process The male rotor rotates counterclockwise, while the inner thread rotates clockwise. In the figure, the upper end of the rotor is the suction section and the lower end is the exhaust end. Compression process The end face is the exhaust end face. Here, the positive rotor rotates clockwise and the negative rotor rotates counterclockwise. In the figure, the upper end of the rotor is the suction section and the lower end is the exhaust end. Exhaust process In the exhaust process of the screw pump, the exhaust process begins after the volume between the teeth is connected to the exhaust port. With the continuous reduction of the volume between teeth, the gas with exhaust pressure is gradually discharged through the exhaust port. Overall, the role of screw vacuum pump is still very large, and relatively speaking, the future prospects are also good, I believe that with the improvement of science and technology, the future of screw vacuum pump can also be improved.
