  • Publication number: 20200158134
    Abstract: Embodiments of the present disclosure describe a reflux device blade, a compressor structure 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.

  • Publication number: 20200063754
    Abstract: An integrated structure of a return device and a pressure diffuser, and a centrifugal compressor are provided. The structure includes a pressure diffuser portion and a return device portion integrally molded with the pressure diffuser portion. The pressure diffuser portion is configured to form a pressure diffusion flow channel. The return device portion has a return channel. The return channel is in communication with the pressure diffusion flow channel, and is configured to guide gas from the pressure diffusion flow channel. The structure of the present invention eliminates a need of independently installing a return device and a pressure diffuser, and eliminates connection seams caused by assembly and misalignment caused by accumulated errors. Therefore, gas can smoothly flow through the pressure diffusion flow channel into the return channel, such that a gas flow is well guided, and the gas flow uniformity is better.
