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.

Compressor rotor structure and method for arranging said rotor structure

Compressor rotor structure for turbomachinery, such as a compressor, is provided. Disclosed embodiments can benefit from sealing sleeves that may be arranged to inhibit passage onto respective hirth couplings of process fluid being processed by the compressor. The sealing sleeves may be affixed to adjoining structures (e.g., adjoining impeller bodies) by way of a slip fit connection to one of the adjoining structures and an interference fit connection with respect to the other adjoining structure, which is conducive to a user-friendly assembly of the sealing sleeves with the adjoining structures.

Housing of turbo compressor

An arrangement having an annular seal extending about a machine axis, and a vessel for sealing an L-shaped gap extending along a circumferential direction between a main vessel body and a cover is provided. A radial section of the gap extends in the radial direction and circumferential direction, and an axial segment extends in the axial direction and the circumferential direction. A sealing chamber is provided in the region where the radial segment and the axial segment intersect, the chamber expanded radially and axially relative to the adjacent gap segments. A seal is disposed in the sealing chamber, and a greater pressure is present in the radial segment than in the axial segment, the pressure differential sealed by means of the seal. The seal includes a support ring disposed radially inward made of a first material, and a jacket element made of a second material.

Arrangement having a seal, seal, and turbocompressor

A turbomachine foot unit with a plurality of feet is provided. The plurality of feet is fastened to a turbomachine. The turbomachine stands upright on a horizontal base. The turbomachine foot includes fastening devices for fastening the feet to the base. At least one of the feet is mounted in a horizontally moveable manner relative to one of the fastening devices fastening the foot to the base.
