Apparatus and method for removing gas turbine compressor stator vane segments with rotor in place

摘要

An apparatus (100) and method (300) adapted to facilitate removal of stator vane segments (50) from a casing slot (20) of a lower casing (10) of a rotating machine (5) with stator vanes segments (50) and rotating blades. The apparatus (100) includes a compression device (110) adapted to apply a pushing force (115) on a rear surface (116) of a trailing stator vane segment (51), a clearing element (200) adapted to free adhesion materials (40) holding a stator vane segment (50) to the casing slot (20) of the lower casing (10) of the rotating machine (5), and a tension device (220) adapted to apply a pulling force (165) on a forward part (166) of a leading stator vane segment (53).
