  • Patent number: 8978243
    Abstract: A turbomachine is provided. The turbomachine comprises a compressor, at least two magnetic bearings provided at opposite ends of a compressor shaft, a motor having a motor shaft, a first electrical cable having a first end, a second end, an internal core section and an outer sheath section with the internal core section and the outer sheath section extending from the first end to the second end, a first connector configured to connect the first end to the first magnetic bearing, wherein the first connector is welded or brazed to the first end to both the internal core section and the outer sheath section, and a second connector configured to connect the second end to the first external connection, wherein the second connector is welded or brazed to the second end to both the internal core section and the outer sheath section.

  • Patent number: 8282344
    Abstract: A balancing group (22) is described for the rotor of a fluid rotary machine (10), wherein the rotor is of the type comprising at least one shaft (16) equipped with an internal pass-through hole (20) which develops along the longitudinal axis (A) of the shaft (16). The balancing group (22) includes at least a first inner element (24) and at least a second outer element (26), the first inner element (24) being suitable for being engaged by interference, in the direction of the longitudinal axis (A), inside the second outer element (26). The balancing group (22) thus formed is suitable for being inserted, in the direction of the longitudinal axis (A), inside the pass-through hole (20) of the shaft (16).

  • Patent number: 7874790
    Abstract: Convex sealing bottom (10) for a twin-shaft turbine of the type comprising a series of convex disks constrained to each other by means of a series of pins, each disk of said disks comprises an outer shaped edge which is engaged with a corresponding annular surface (71) of an inner grooved surface (72) of a ring (70) for obtaining an axial seal. The series of disks comprises three disks, a first disk (12), a second disk (13) and a third disk (14) respectively. The three disks are fixed to each other centrally by means of a series of spokes (30) and are constrained in pairs respectively by means of a series of pins which are arranged orthogonally to the three disks to minimize the relative movements of the three disks in an axial direction at the same time allowing the radial dilatations of the three disks themselves.
