  • Patent number: 9879567
    Abstract: A securing device for securing a rotor of a turbomachine against tilting is provided, the rotor being arranged perpendicular in relation to a horizontal plane. The securing device includes a support surface enabling the rotor to be laterally supported in relation to the securing device. The rotor or the tie rod, arranged in an essentially vertical manner, are oriented vertically such that during an alignment, the support surface on which the rotor or the tie rod support, are displaced such that rotor is perpendicular in relation to the horizontal plane.

  • Patent number: 9486886
    Abstract: A device for pivoting a rotor of a turbomachine from a first—preferably horizontal—position into a second—preferably vertical—position is provided. The rotor includes a plurality of rotor discs held together by at least one tension rod, the device includes two sidewall elements arranged parallel to one another, a bridge element connecting the sidewall elements to one another, and a divisible turning ring for form-fittingly holding an axial section of the rotor to be positioned perpendicularly. The rotor further includes two pins rotatably seated in the sidewall elements and arranged flush to the turning ring in order to pivot the turning ring about a pivot axis parallel to the horizontal plane. The bridge element includes a disk, wherein the disk is movable perpendicularly to the horizontal plane in order to be bolted in a flange-like manner onto a rotor retained by the device.

  • Patent number: 8667678
    Abstract: An assembly device for assembling and disassembling a rotor of a turbomachine with rotor disks that are clamped together by at least one tie rod is provided. The assembly device includes a turning block that is secured to a base and a securing device that secures the rotor against tilting. The rotor is arranged in a transversal manner in relation to a horizontal plane of the base and pivotably mounted on the turning block. The securing device is fixed to the base by several supports and the turning block is arranged inside the surface of the base that is clamped by the supports. Large forces and torque coming from the rotor that is arranged in a perpendicular manner are guided from the securing device to the base.

  • Patent number: 7762112
    Abstract: The invention relates to a fitting device for producing the arrangement for locking a sealing element, arranged at the front end on a rotor of a turbine, against a displacement in the circumferential direction, the sealing element locking moving blades arranged on the rotor against an axial displacement. Furthermore, the invention comprises a method of producing the arrangement for locking a sealing element, arranged at the front end on a rotor of a turbine, against a displacement in the circumferential direction. The quality of the fitting can be further increased by means of a modular, mobile fitting device which secures the sealing element for the duration of the bending operation.

  • Patent number: 7752847
    Abstract: The invention relates to a method for cooling a gas turbine comprising a rotor, said method being carried out after the operation of the gas turbine and whereby the rotor is driven at least intermittently during a cooling phase at a reduced nominal speed. To provide a gas turbine with a reduced down time, a liquid is introduced at least intermittently into the air stream upstream of the compressor during the cooling phase.
