Title
(ZH) 压缩机轴承冷却
Abstract
(ZH)

压缩机(22)具有壳体组件(40),该壳体组件(40)具有吸入端口(24)、排出端口(26)和马达隔室(60)。电动马达(42)具有在该马达隔室内的定子(62)和在该定子内的转子(64)。该转子安装成用于围绕转子轴线(500)旋转。一个或更多个工作叶轮(44)联接至该转子,以在至少第一条件下由该转子驱动,以便穿过该吸入端口取入流体且从该排出端口排出该流体。入口导向叶片(IGV)阵列(174)在该吸入端口(24)与该一个或更多个叶轮(44)之间。一个或更多个轴承系统(66、68)支撑该转子(64)和/或一个或更多个叶轮(44)。一个或更多个主排泄通道(120、234、206;120、232、202、206)联接至该轴承,以将流体沿排泄流路从该轴承传递至在该叶轮上游和该IGV阵列下游的位置(172)。
