FIELD: power industry.
SUBSTANCE: impeller design is described. Impeller has disc configuration with R radius, consists of hub, transverse-longitudinal frame rigidly attached to it and attached from above and from below to casing. Transverse-longitudinal frame is radial-annular, consists of radial ribs of the shape of radial section of disc and incomplete ribs installed in middle and peripheral parts of discs uniformly in circumferential direction, which are rigidly attached to several inner annular vertical spars. At that, outer external spar is reinforced, and height of impeller h1 in hub is more than height in peripheral end part h2.
EFFECT: creation of impeller design of electromechanical unit.
