CENTRIFUGAL COMPRESSOR

摘要

Disclosed is a centrifugal compressor capable of minimizing leakage of fluid while realizing high aerodynamic performance in the process of compressing the fluid. The centrifugal compressor includes an impeller having blades, a housing formed with an inlet and an outlet, a sealing unit disposed adjacent to one of the inlet and the outlet, and a partial shroud disposed adjacent to the sealing unit and formed at one of the inlet and the outlet to partially surround outer peripheral portions of outer ends of the blades.

1. A centrifugal compressor comprising:
an impeller comprising a plurality of blades radially disposed about a rotational axis; a housing comprising an inlet into which a fluid to be compressed by the impeller is introduced, an outlet through which the compressed fluid is discharged, and an inner surface adjacent to the plurality of blades; a sealing unit disposed adjacent to one of the inlet and the outlet to seal a space between outer ends of the plurality of blades and the inner surface; and a partial shroud disposed adjacent to the sealing unit and disposed at one of the inlet and the outlet to partially surround outer peripheral portions of the outer ends of the plurality of blades.
