Abstract: Introduction was made to the problems produced in the operational process of generator set eleven in three gorges left bank after the thrust block runner plate assembled. By the way of artifactitious fission mode respectively, the assembly of thrust block runner plate was repaired. This paper gave the technological process of thrust block repair, runner plate repair and the entirety repair of thrust block runner plate. The practical application results show that this scheme can make the generator set continuously operate stably after the generator set reassembled,which provides repairing technology reference for the assembly of thrust block runner plates with similar structure.
Key words: thrust block; runner plate; repair; honing mirror surface
