  • Patent number: 9885246
    Abstract: A sealing arrangement for a duct, through a stationary housing, of a shaft which rotates about an axis is provided, wherein a sealing liquid is used for sealing instead of sealing steam. The sealing arrangement includes a seal, having a vapor steam extraction system, and a feed line, which is arranged between the inner space and the vapor steam extraction system and is designed for supplying a sealing liquid, wherein a labyrinth seal, a brush seal with metallic bristles, a brush seal with bristles made of natural fibers and/or a brush seal made of synthetic fibers is provided for sealing off with respect to the inner space and the vapor steam extraction system.

  • Publication number: 20160265374
    Abstract: A mounting device for mounting a guide blade to be mounted in a blade groove of a turbine, where the mounting unit has a clamping unit and a pressing unit. Here, the clamping unit is designed to produce in the blade groove a non-positive connection in a circumferential direction. The pressing unit is arranged behind the clamping unit in the circumferential direction and the pressing unit is supported against the clamping unit in the circumferential direction. The pressing unit is designed to apply a pressing force by means of a pressing piston in an opposite direction to the circumferential direction in a mounting direction and to transmit said force to the guide blade to be mounted.

  • Patent number: 8956122
    Abstract: A safety device for a turbine blade is provided. The safety device includes a shear pin, a clamping piece and a securing element, wherein the shear pin is arranged in a corresponding bore in the turbine blade foot and the clamping piece is designed having an upper limb and a lower limb, wherein the clamping piece exerts a radial force on the turbine blade foot for radial safeguarding.

  • Patent number: 8192167
    Abstract: A turbine-blade locking device having a wedge movable in an axial direction is disclosed. The wedge is movable in the axial direction by a tensioning device, as a result of which a force is produced in the axial direction. The force in the axial direction causes the turbine blade to be pressed against the blade holder.
