Abstract

PURPOSE: To reduce the disc friction loss in the operation of a centrifugal compressor by providing a construction wherein the impeller is threaded at its peripheral portion so as to be screwed and fixed easily by a simple tool to a disc-shaped support member provided at the shaft end, and the area of contact of the rotary part with the high-pressure fluid is reduced.
CONSTITUTION: An impeller 1 is provided at its peripheral portion with a thread (male thread) 8c. A disc shaped support member 7 fixed to the end of a shaft 2 is provided at its peripheral portion with an annular edge 7c in the inner peripheral surface of which formed is a thread (female thread) for screwing engagement with the thread 8c of the impeller, so that the impeller 1 can be screwed and fixed to the support member. The support member 7 is provided at its central portion with a cylindrical projection 7b which fits in a cylindrical recess 8b formed at the center of the impeller 1, so that both members are correctly centered with respect to each other. The friction surface 7a of the support member 7 and the friction surface 8a of the impeller 1 are made to closely contact each other by the screwing engagement between two members. In consequence, the clearance behind the impeller 1 is eliminated to reduce the area of contact with the high-pressure fluid to reduce the disc friction loss.
