Axial flow compressor and centrifugal compressor both belong to speed type compressor, which are called turbine type compressor.
The meaning of speed compressor is that their working principle is to rely on the blades to work on the gas, and to greatly improve the flow velocity of the gas first, and then to transform kinetic energy into pressure energy.
The meaning of turbine compressor is that they all have high-speed rotating blades. "TURBINE" is the transliteration of "TURBINE" in English, and its Chinese meaning is "blade-type machine". For this English word, no matter which language in the world, transliteration is adopted.
So the meaning of "turbine compressor" is blade type compression machine.
Compared with centrifugal compressor, because the flow of gas in compressor is not in the direction of radius, but in the direction of axial direction, the biggest feature of axial compressor is: the gas flow capacity per unit area is large, under the premise of the same amount of processing gas, the radial dimension is small, which is especially suitable for occasions requiring large flow.
In addition, axial flow compressor also has the advantages of simple structure, convenient operation and maintenance, etc. However, it is obviously inferior to centrifugal compressor in the aspects of complicated blade lines, high requirements of manufacturing process, narrow stable working area and small flow regulation range under constant rotating speed, etc.
