Abstract: A shroud for a compressor is provided. The shroud may include an inner annular member and an outer annular member. The inner annular member may include an abradable material disposed between a first end portion and a second end portion thereof. The inner annular member may further be contoured between the first end portion and the second end portion thereof. The inner annular member may be configured to be disposed proximal an impeller of the compressor such that the inner annular member and the impeller define a clearance therebetween. The outer annular member may extend axially from the second end portion of the inner annular member. The outer annular member may be configured to compliantly mount the shroud with a casing of the compressor.

Abstract: A compressor may include a casing defining a discharge cavity and a seal cavity. A rotary shaft may be disposed in the casing, and a shaft seal assembly may be disposed in the seal cavity and about the rotary shaft. An impeller may be coupled with and configured to be driven by the rotary shaft. A balance piston may be integral with the impeller and may define the discharge cavity and the seal cavity. A balance piston seal may be disposed about the balance piston such that the balance piston seal and the balance piston define a radial clearance therebetween. The radial clearance may be configured to provide fluid communication from the impeller to the discharge cavity. A heat shield may be disposed in the discharge cavity, and may be configured to prevent the conduction of heat from the discharge cavity to the seal cavity via the casing.
Abstract translation: 压缩机可以包括限定排出腔和密封腔的壳体。 旋转轴可以设置在壳体中，并且轴密封组件可以设置在密封腔中并且围绕旋转轴。 叶轮可以与旋转轴联接并构造成由旋转轴驱动。 平衡活塞可以与叶轮成一体，并且可以限定排出腔和密封腔。 平衡活塞密封件可以围绕平衡活塞设置，使得平衡活塞密封件和平衡活塞在其间限定径向间隙。 径向间隙可以被配置为提供从叶轮到排出腔的流体连通。 隔热罩可以设置在排放腔中，并且可以被配置为防止热量经由壳体从排出腔传导到密封腔。
