| Abstract: | The defect of runner blade crack is a common problem to a large Francis turbine.If the crack is serious,it will seriously threaten the hydropower station operation safety and stability.In view of the run- ner blade cracking probably occurred in Three Gorges Hydropower Station,the reasonable proposals and feasible methods are put forward to eliminate the defect. |
