Abstract
A method and an apparatus for mobile repair of a stationary rotor seals of a turbo machine is provided. The method includes the following steps, 3D-scanning of the stationary seal, generation of 3D-model of the stationary seal, removing of the damaged spots of the seal using laser cutting, and generating a new seal at the repair spot by use of a second process head, which generates the seal by laser powder cladding. The apparatus includes a 3D-scanner, a cutting tool, and a first process head and a second process head.
Claims11
A mobile repair apparatus for repairing a stationary rotor seal of a turbo machine, comprising:
- a 3D-scanner configured to scan the stationary rotor seal;
- a cutting tool of a first process head configured to remove a plurality of damaged spots of the stationary rotor seal at a repair spot;
- and
- a second process head for configured to generate a new seal at the repair spot by powder cladding,
- wherein the first process head comprises a first laser device for cutting;
- wherein the first process head is configured to remove the plurality of damaged spots from a stationary casing of the turbo machine, said stationary casing comprising the stationary rotor seal;
- wherein the second process head is configured to generate the new seal at the stationary casing of the turbo machine;
- and wherein the first and second process head are positioned relative to the stationary rotor seal upon removal of a rotor from the turbo machine.
