摘要： A volute for use in a centrifugal compressor that includes an impeller. The volute includes a housing defining a central aperture, an inlet channel, and a fluid collecting channel. The central aperture is adapted to receive the impeller such that the impeller discharges a fluid to the inlet channel. The inlet channel directs the flow to the collecting channel. A discharge portion is coupled to the housing and includes a discharge passage in fluid communication with the collecting channel to discharge the fluid. A tongue portion is disposed between the collecting channel and the discharge portion. The tongue is operable to separate the fluid into a first flow that flows through the collecting channel and a second flow that flows through the discharge passage.
摘要翻译：一种用于包括叶轮的离心式压缩机的蜗壳。蜗壳包括限定中心孔的壳体，入口通道和流体收集通道。中心孔适于接收叶轮，使得叶轮将流体排放到入口通道。入口通道将流引导到收集通道。排出部分联接到壳体并且包括与收集通道流体连通以排出流体的排出通道。舌部设置在收集通道和排出部之间。舌头可操作以将流体分离成流过收集通道的第一流量和流过排放通道的第二流量。

摘要： A diffuser for use in a centrifugal compressor that includes an impeller that discharges a high-velocity flow of fluid. The diffuser includes a platform having a blade portion and defining a substantially circular aperture. The impeller is disposed at least partially within the aperture such that the high-velocity fluid exits the impeller in directions that are substantially tangent to the blade portion. A vane extends from the platform and includes a suction side, a pressure side, and a leading edge having a platform portion and a shroud portion. A majority of the shroud portion is disposed on the suction side of a line normal to the platform that passes through a center of the platform portion of the leading edge. A shroud is coupled to the shroud portion of the vane such that the vane, the platform, and the shroud cooperate to at least partially define two flow paths.

摘要： An impeller rotatable in a direction of rotation in a centrifugal compressor including an intake ring. The impeller includes a back plate having a shaft portion and a plurality of blades. Each blade extends from the back plate and includes an inducer portion adapted to draw fluid into the impeller and including a leading edge and an exducer portion adapted to discharge the fluid from the impeller and including a trailing edge. A blade pressure side is defined between the leading edge, the trailing edge, the back plate, and a blade tip. The pressure side is convex from the back plate to the blade tip. A blade suction side opposite the pressure side is defined between the leading edge, the trailing edge, the back plate, and the blade tip. The suction side being concave from the back plate to the blade tip.
