A compressor rotor for turbomachinery, such as a centrifugal compressor, is provided. Disclosed embodiments include a tie bolt and a rotor shaft that cooperates with the tie bolt to define a chamber therebetween. A seal assembly is positioned to separate the chamber from a first space and a leak detector in fluid communication with the first space and operable to generate a signal indicative of leakage of a fluid from the chamber to the first space.

In a turbomachine, rotor structure with seal assembly and method in connection with same

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.
