introduction: Power compressor with high speed rotating impeller(See turbine machinery)。It relies on the interaction between the rotating impeller and the air flow to increase the gas pressure﹐At the same time, the airflow generates acceleration and gains kinetic energy﹐The airflow is then slowed down in the diffuser﹐Convert kinetic energy into pressure energy﹐Raise the pressure further。The gas flow is continuous in the compression process。Turbine compressor is developed on the basis of fan。It is widely used to transport air and various gases in various processes﹐And increase its pressure。 sort According to the direction of gas flow﹐Turbine compressors are mainly divided into axial flow and centrifugal type
