IMPELLER OF CENTRIFUGAL COMPRESSOR

摘要

An impeller of a centrifugal compressor includes a main disc with blades; cover disc fixed on the end surfaces of the blades, with its inner surface arranged as conical, with straight linear generatrix of the cone; and inter-blade channel formed with the inner surfaces of the discs. The impeller additionally includes a movable blade-less diffuser. The inner surface of the main disc is arranged as conical, with straight-line generatrix of the cone. The inner surfaces of both discs have same parameters of the angles at the tops of the cones. The meridian plane of the inter-blade channel is symmetrical with respect to the axis of centrifugal forces and the axis of the movable blade-less diffuser.
