摘要:
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).
摘要(中):
离心式压缩机(22,22')包括壳体(30),入口导向叶片(32a,32b),叶轮(34a,34b),马达(38),扩散器 (36a,36b)和冷却介质输送结构(SS,SR,RS,RR,IC,OC,G,80)。 电动机38包括安装在轴42上的转子62和设置在转子62径向外侧的定子60,以在转子62和定子之间形成间隙G, 60)。 冷却介质输送结构(SS,SR,RS,RR,IC,OC,G,80)包括入口(IC)和出口(OC)管道,用于向马达38和马达38提供和排出冷却介质。 轴(42)具有与转子(62)的内部形状不同的外部形状,以在轴(42)和转子(62)之间形成至少一个轴向通道(80)。 通过间隙(G)和至少一个轴向通道(80)供应冷却介质以冷却转子(62)。 p>
