Title:
DEFORMATION ADJUSTMENT METHOD FOR LOWER HALF INNER CASING
Document Type and Number:
WIPO Patent Application WO/2024/075568
Kind Code:
A1
Abstract:
A lower half inner casing has a lower half inner casing body forming a semi-circular arc, and an inner casing accessory part provided to the lower half inner casing body. The inner casing accessory part has a protrusion which protrudes radially outward of the lower half inner casing body, and protrudes upward of a lower contact surface of the lower half inner casing body. In this deformation adjustment method for a lower half inner casing in a rotating machine, the following are executed: a preparation step for preparing a deformation adjustment device having an inner casing-side member that is attachable to the protrusion so as to be non-relatively movable in the radial direction; a device arrangement step for attaching the inner casing-side member to the protrusion and arranging the deformation adjustment device around the protrusion; and a deformation adjustment step for pressing, to the radially inward side, the inner casing-side member attached to the protrusion.
