Abstract: A rotor of a gas turbine having two adjacent rotor discs, on each of which moving blades are fastened, an annular rotor component being arranged between the rotor discs and having at its opposite ends circumferential annular grooves, in each of which a circumferential fastening projection on the respective rotor disc engages. When the rotor is stationary a first outer flank of the first annular groove rests under pressure against a first outer flank of the first fastening projection and there is play between a first inner flank of the first annular groove and a first inner flank of the first fastening projection.

Abstract: A process water analysis sampling assembly includes an immersion probe having a first filter unit and a second filter unit which are fluidically separated from each other, a flushing liquid tank, and a fluidics control. The fluidics control includes a pump arrangement which is fluidically connected to each of the first filter unit and the second filter unit, at least two liquid pumps which are arranged to be mutually independent from each other, and a valve arrangement having plurality of switchable valves. The fluidics control controls a sampling and a flushing of the immersion probe. The fluidic control fluidically connects the flushing liquid tank to one of the first filter unit and the second filter unit and simultaneously connects an analysis unit to the other one of the first filter unit and the second filter unit.

Abstract: An annular clamping nut which is provided for being placed onto the end of a tie bar, in order to brace the latter, and which has in addition to a central recess for receiving the tie bar parallel to a longitudinal direction passages at uniform radial spacings in the ring circumferential direction which are directed parallel to the longitudinal direction of the central recess and are provided for receiving clamping screws. An external thread is provided on the outer surface of the clamping nut, which outer surface is arranged on a side which lies substantially opposite the wall of the central recess, which external thread runs substantially in the ring circumferential direction of the outer surface.

Abstract: A method for mounting rotor blades on a rotor disk along a predetermined pitch circle diameter in such a way that adjacent rotor blades, when properly mounted on the rotor disk and in the cold state, are clamped against each other with a predetermined preload. A clamping device which performs such a method has a plurality of clamping elements which are arranged in a uniformly distributed manner around a central axis, the number of which corresponds to the number of rotor blades to be mounted on the rotor disk and which in each case are designed for the locating of a rotor blade, wherein the clamping elements are moveable radially, exerting a radially inwardly directed force.
