Abstract
The invention relates to a method and a device for demounting a turbine blade (1) out of an axial groove (3) of a rotor (8) or stator. The turbine blade (1) is demounted with a hydraulic device (9, 10) by means of a hooked slide (4) which is located in a gap (7) between the blade base of the blade root (2) and the groove bottom of the axial groove (3). At the same time, the hooks (5) of the hooked slide (4) engage into clearances which are located at the blade root (2).
Claims9
A method for demounting a turbine blade (1) which is fastened in an axially oriented groove (3) of a rotor (8) or stator of a turbomachine by means of a blade root (2), characterized in that the turbine blade (1) is drawn out of the circumferential groove (3) in the axial direction by means of a device (4, 10, 11, 15) which engages on the blade root (2) of the turbine blade (1).
The demounting method as claimed in one of the preceding claims, characterized in that the turbine blade (1) is a guide vane or moving blade of a gas turbine, steam turbine or compressor.
