  • Patent number: 11971043
    Abstract: A diffuser system for a centrifugal compressor is provided. The diffuser system includes a nozzle base plate that defines a diffuser gap, support blocks, and a drive ring rotatable relative to the support blocks. The drive ring includes cam tracks and bearing assemblies positioned proximate an outer circumference of the drive ring. The diffuser system further includes drive pins extending through the support blocks and the nozzle base plate. The first end of each drive pin includes a cam follower mounted into a cam track on the drive ring. The second end of each drive pin is coupled to a diffuser ring. Rotation of the drive ring causes axial movement of the drive pins by movement of the cam followers in the cam tracks. This results in movement of the diffuser ring to control fluid flow through the diffuser gap.

  • Patent number: 11959485
    Abstract: Compressor rotor structure and methodology for harmonizing compressor aerodynamics and rotordynamics are provided. Disclosed embodiments benefit from a compressor design effective for improving rotordynamics (e.g., stiffer rotor structure) without reducing a usable aerodynamics range of the compressor. This design may involve variation of the rotor structure along the rotor axis to locate respective surfaces defined by respective inlets of the one or more impellers at a varying distance relative to the rotor axis based on respective ratios selected for the configuration of the impeller bodies. This arrangement may be effective for improving rotordynamics while satisfactorily meeting the respective varying aerodynamics requirements at the various compression stages by the impeller bodies.
