A compressor is provided with a substantially tubular compressor casing, a substantially circular lid that is provided inside an inner periphery of the compressor casing so as to close off an end surface of the compressor casing, a space that is enclosed by the lid and an inner circumferential surface of the compressor casing so as to accommodate a blade, and seal member that is provided in a circumferential direction on the space side of an outer circumferential surface of the lid, wherein a slit part is provided on the lid, radially inside the outer circumferential surface, where the seal member is provided, so as to extend in the axial direction from the space side of the lid.

Compressor

A compressor including: a substantially tubular casing; a substantially cylindrical lid that is provided inside an inner periphery of the casing so as to close off both ends of the casing; a space that is enclosed by the lid and an inner circumferential surface of the casing so as to accommodate a blade; and a seal member that is provided so as to extend in a circumferential direction on the space side of an outer circumferential surface of the lid. A recessed portion, extending inward in the radial direction from the outer circumferential surface of the lid, is provided on the lid at a position between the seal member and the end surface at the space side of the lid.

An assembling and disassembling device for a compressor has a substantially cylindrical bundle that is received insertably and removably on an inner circumferential surface of a substantially tubular compressor casing that is mounted horizontally and further includes: a plate-like member that is provided on an axial end portion of the bundle at an opposite side of an insertion direction so as to protrude outward in a radial direction of the bundle and a threaded-rod member that inserts and removes the bundle connected to the plate-like member into and from the compressor casing by being screwed into a threaded hole provided in the plate-like member and being rotated.

Compressor, assembling and disassembling device therefor, and assembling and disassembling method therefor

A fixture used in a rotary machine which includes a rotary unit which has a rotary shaft, and a stationary unit which rotatably supports the rotary shaft, includes: a plate which comes into contact with an end portion of the rotary shaft; a fastening member which fixes the plate to the end portion of the rotary shaft; and a constraining member which connects the plate and the stationary unit, and constrains the plate from moving with respect to the stationary unit in an axial direction and a rotation direction.
