CENTRIFUGAL COMPRESSOR IMPELLER

摘要

The invention relates to the field of centrifugal compressors and, in particular, to an impeller 201 of a centrifugal compressor 3 comprising a disc 202 and blades 205 secured to the disc 202 on a front surface 203 of the disc 202. An intersection point of the trailing edge 207 and the blade root 215 is further forward by at least one half thickness of the disc 202 than the blade root 215 with an intermediate diameter D of the impeller 201, and an intersection point of the trailing edge 207 and the blade head 216 is also further forward than the blade head 216 with an intermediate diameter Di of the impeller 201.
