Title:
モータ冷却を有する遠心圧縮機
Document Type and Number:
Japanese Patent JP7139249
Kind Code:
B2
Abstract:
A centrifugal compressor (22, 22') includes a casing (30), an inlet guide vane (32a, 32b), an impeller (34a, 34b), a motor (38), a diffuser (36a, 36b) and a cooling medium delivery structure (SS, SR, RS, RR, IC, OC, G, 80). The motor (38) includes a rotor (62) mounted on the shaft (42) and a stator (60) disposed radially outwardly of the rotor (62) to form a gap (G) between the rotor (62) and the stator (60). The cooling medium delivery structure (SS, SR, RS, RR, IC, OC, G, 80) includes inlet (IC) and outlet (OC) conduits located to supply and discharge a cooling medium to and from the motor (38). The shaft (42) has an external shape different than an internal shape of the rotor (62) to form at least one axial passageway (80) between the shaft (42) and the rotor (62). The cooling medium is supplied through the gap (G) and the at least one axial passageway (80) to cool the rotor (62).
