Reflux device blade compressor
Embodiments of the present disclosure describe a reflux device blade and a compressor. The reflux device blade includes a blade main body, a hollow cavity is formed in the blade main body, and an air supplement hole is formed in the blade main body. When the hollow reflux device blade is adopted, the supplemental air entering the hollow cavity of the reflux device blade through an air supplement channel forms jet flow on a suction surface of the reflux device blade to blow off a low-speed low-energy area formed on the suction surface, so as to reduce the airflow mixing loss, prevent the intake distortion of a second-stage impeller, and improve the operation range of the compressor.
