    摘要: A compressor wheel for a compressor of a turbocharger has a hub (16) and a multiplicity of blades (12) on the hub (16). In intermediate spaces of the multiplicity of blades (12), a channel is in each case formed between a suction side (24) and a pressure side (26). The channel guides fluid that flows in axially in relation to a rotation axis (22) radially or radially-axially outward. The hub (16) in relation to the rotation axis (22) in at least one channel is contoured with a rotationally symmetrical portion (18′) and a non-rotationally symmetrical portion (18). The non-rotationally symmetrical portion (18) is formed by radii that are variable in the flow direction, and a transition region (28) between the hub (16) and the blade (12) adjoins the non-rotationally symmetrical portion (18).

    摘要: A rotary assembly is provided that may be operably connected to an engine. The rotary assembly may include a rotary device comprising a turbine wheel, a shaft connected to the turbine wheel, and a case that houses the shaft and the turbine wheel. The turbine wheel may receive exhaust gas from the engine which causes rotation of the turbine wheel and the shaft. The case may include an interior surface that defines a hollow volume in which the turbine wheel and the shaft are located. The case has a radial thickness extending from the interior surface to an exterior surface of the case. The case may include a lattice structure integrated within the radial thickness of the case. The lattice structure may include a repeating three-dimensional array of frame segments connected to one another at junctions and defining interstitial spaces between the frame segments.

    摘要: Methods, apparatus, systems, and articles of manufacture are disclosed to reduce failure to bearings in a pump system. Disclosed herein is a pump system comprising a shaft connected to an impeller of the pump system, and a bearing to provide a dampening to the shaft, the bearing including a journal lining, the journal lining supported in the pump system, a spring-loaded foil to separate the shaft from the journal lining, an inner lining between the shaft and the spring-loaded foil, and a deformation limiter located between the spring-loaded foil and the journal lining.

    摘要: A system includes a dynamic compressor and a controller. The dynamic compressor includes a motor having a driveshaft rotatably supported within the dynamic compressor and a compression mechanism connected to the driveshaft and operable to compress a working fluid upon rotation of the driveshaft. The controller is connected to the motor and includes a processor and a memory. The memory stores instructions that program the processor to operate the motor to compress the working fluid at a motor speed greater than a predicted minimum surge speed plus a control margin, determine when surge events have occurred, store, in the memory, an indication of each surge event that the processor determined to have occurred, and determine whether or not to take a protective action when the processor determines that a surge event has occurred.

    摘要: A controlled area progression diffuser for a compressor may be defined by a bearing diffuser face of a bearing housing and a compressor diffuser face of a compressor housing that are spaced apart by a diffuser width, and airflow from a compressor wheel enters the controlled area progression diffuser through a diffuser inlet, flows between the diffuser faces, and flows out of a diffuser outlet to a volute. The diffuser faces may be shaped so that the diffuser width decreases as the controlled area progression diffuser extends radially away from the compressor wheel toward the volute so that an annulus area of the controlled area progression diffuser does not increase linearly for at least a portion of a radial length of the controlled area progression diffuser.
