The measuring jig for the rotary machine is a measuring jig for a rotary machine including a casing that extending about an axis, a rotor that is disposed in the casing and extends in an axial direction about the axis, and a plurality of bearings that are disposed at intervals in the axial direction and supports the rotor in the casing. The measuring jig includes a plurality of casing fixing portions that are respectively attachable to and detachable from bearing holding portions to which the bearings are attached in the casing; a main member that extends in the axial direction so as to connect the plurality of casing fixing portions to each other; an arm that extends from the main member in an orthogonal direction orthogonal to the axial direction; and a reference surface that is disposed at a distance from a measurement target part of the casing.

To improve soundproofing performance of a soundproofing wall constituted by wall members overlapping with a hollow portion therebetween. A resonance state of an outer wall member of a soundproofing wall which includes an inner wall member on the side of a sound generation source, an outer wall member outwards from the inner wall member with respect to a position of the generation source, and a hollow portion which is provided between the inner wall member and the outer wall member is detected. A pressure of the hollow portion is adjusted so that the resonance state is a minimum based on adjustment of the pressure of the hollow portion.

A method for measuring a pre-twist amount of a blade includes a spreading dimension acquiring step, a misalignment acquiring step, a correcting step, and a pre-twist amount acquiring step. In the spreading dimension acquiring step, circumferential spreading dimensions of each shroud of two rotor blades are acquired. In the misalignment acquiring step, a misalignment amount in the direction of the axis between the shrouds of two rotor blades adjacent to each other in the circumferential direction is measured. In the correcting step, the spreading dimension acquired in the spreading dimension acquiring step is corrected on the basis of the misalignment amount acquired by the misalignment acquiring step. In the pre-twist amount acquiring step, the pre-twist amount of the blade is acquired on the basis of the spreading dimension corrected in the correcting step.

The present invention provides parts of a rotation machine which effectively prevent particulates, such as silica, iron oxide, and other particles, contained in a gas to adhere to the rotating machines which work with the gases containing the particulates. An intermediated metal-plated film and a plated film containing fluorocarbon polymer particles provided on the intermediate metal-plated film are deposited on the surfaces of moving blades used in a steam turbine. The plated film containing the fluorocarbon polymer particles includes fluorocarbon polymer particles made of any of Ni-based metals and a plated matrix, and some of the fluorocarbon polymer particles are exposed at the surfaces of the plated matrix.
