FIELD: mechanical engineering; centrifugal compressors and high-capacity pumps. ^ SUBSTANCE: proposed stage has working wheel with flat base and conical cover disks and blades between said disks, diaphragms, rotary channels, vane and vaneless diffusers. Wall of vaneless diffuser diaphragms are of different shape relative to setting wall of diaphragm adjacent to inner surface of flat main disk is made concave, and wall of diaphragm adjacent to inner surface of cover disk is made convex. ^ EFFECT: increased efficiency of stage. ^ 1 dwg |
