Centrifugal compressor vane type diffuser

The utility model discloses a vane diffuser of a centrifugal compressor, which is composed of a base and a blade. There are four mounting holes and two disassembly holes on the base. The base is characterized in that the base is circular, the blade is wing-shaped, the blade is evenly distributed on the base, and the blade is deflected counterclockwise, totally 13 pieces are adjacent to each other.There is no geometric throat in the blade. The X Y coordinate system is established with the center of the base as the origin. The root of the blade is located on the Y axis. The four mounting holesare distributed in four quadrants. The angles between the blade and the Y axis are 45, 35, 35, 45, and two disassembly holes in quadrant order. Distribution in the first quadrant and the third quadrant, with the X-axis angle of 8, 8, the installation hole and the removal hole of the center of the circle are located on the outer edge of the blade trajectory. The utility model has the advantages that the loss along the flow
