CENTRIFUGAL COMPRESSOR IMPELLER
Document Type and Number:
WIPO Patent Application WO/2016/092873
Kind Code:
A1
Abstract:
Provided is a centrifugal compressor impeller capable of improving machine operation efficiency, by making the total pressure distribution of a fluid that flowed into a vaneless diffuser constant. To this end, the provided centrifugal compressor (1) impeller (30) has a plurality of vanes (33) radially provided around a rotating shaft (20), uses centrifugal force produced by rotating along with the rotating shaft (20), pumps a fluid (G) taken in from the leading edge (33a) side of the vanes (33) to the outside in the radial direction of the rotating shaft from the trailing edge (33b) side of the vanes (33), and thereafter, discharges the fluid (G) into a vaneless diffuser (12). Furthermore, the edge front end (41) and the edge rear end (41) of the trailing edge (33b) are positioned to the outside in the radial direction of the rotating shaft relative to the edge center section (43) of the trailing edge (33b).
