TURBO COMPRESSOR

摘要

A turbo compressor comprising a driving motor (20), an impeller (40) to be rotated by the driving motor (20), a second gas suction part (45) through which gas is introduced into the impeller (40), and a discharger (47) through which the gas is discharged from the impeller (40), the turbo compressor comprises a shroud (60) provided between the gas suction part (45) and the gas discharger (47) and spaced from a blade (43) of the impeller (40); and a plurality of channels (61) provided on the shroud (60) and inclined toward the gas discharger (47) along a rotating direction of the impeller (40). With this configuration, the present invention provides a turbo compressor in which compression efficiency is increased by eliminating a backflow and a leakage flow.
