Device for generating a dynamic axial thrust to balance the overall axial thrust of a radial rotating machine

摘要

An impeller wheel assembly (2) for a radial rotating machine (1), comprises a bladed hub portion (4) of an impeller wheel, with a second radially outward facing, gas deflecting surface (14) having a curvature profile designed to deflect an axial gas flow into a radial centrifugal flow, and comprising a deflector portion (3) with a first radially outward facing, gas deflecting surface (13). The first radially outward facing surface (13) has a curvature profile designed to deflect a radial centripetal gas flow (28) into an axial gas flow (26).
