Abstract:
The present application provides a stator blade, a compressor structure and a compressor. The stator blade comprises a blade body, wherein a cavity is formed inside the blade body, and a gas supply hole is formed on the blade body. The present application forms a jet on the suction surface of the stator blade by supplemented gas, thereby blowing off the low-speed low-energy region formed by the suction surface, reducing the gas flow mixing loss caused by the supplemented gas, thereby improving the aerodynamic efficiency of the centrifugal compressor.
