Embodiment Construction

[0019] figure 1 Reference numeral 1 in represents a gas turbine power generation device.

[0020] The device 1 extends along a longitudinal axis A and comprises a combustion chamber 2, a stator 3 and a rotor 4 rotating about the axis A (all in figure 1 shown schematically).

[0021] The stator 3 comprises a stator housing 5, which extends the entire length of the rotor 4 around an axis A and is stationary; and a plurality of stator blades 7 fastened to the stator housing 5 and to respective stator rings 6 .

[0022] The rotor 4 comprises a shaft 8 extending along an axis A; a plurality of rotor disks 9 interconnected so as to define a single member for rotation about the axis A; layout.

[0023] Each rotor blade 10 is provided with a free end 11 and an end 12 connected to the respective rotor disk 9 .

[0024] The stator rings 6 extend around the rotor disk 9 and are spaced apart from each other such that the radial array of rotor blades 10 is staggered along the axis A b...

Abstract

The invention provides a repair method for a gas turbine power plant (1) comprising replacing a bearing assembly ( 16) thrust ring (29, 38; 30), different thicknesses (NR) as between the thrust surface (51) and at least one adjoining surface (53) of the wall (50) of the thrust ring (29, 38; 30) axial length.

Description

technical field [0001] The invention relates to a maintenance method and kit for a gas turbine power generation device. Background technique [0002] Gas turbine power plants are known to include a rotor extending along a longitudinal axis and provided with a plurality of rotor blades, and to include a stator housing extending generally around the rotor. [0003] The rotors in gas turbine power plants of this type are constantly subject to radial movements, mainly due to thermal expansion phenomena and the centrifugal effects experienced by the rotors during plant operation. [0004] During operation of the device, the axial movement of the rotor can determine excessive proximity or excessive distance between the rotating part (rotor blades) and the stationary part (stator housing) of the device, disregarding the precautions defined in the device design steps. This excessive proximity establishes a risk of collision between the rotating and stationary parts, while an excess...
