| Abstract: | There are some cracks found on No. 4 and No. 15 guide blades in the first routine repair after the extension of No. 3 water- turbine generator set for the first time in Tian Shengqiao Second Hydroelectric Power Plant, then after the treatment, there are still some cracks found on No. 4 and No, 15 guide blades and new cracks found on No. 12 guide blade during the second routine repair. Except that a crack on No, 15 guide blade is the previous weld crack, other cracks on No. 4 and No. 15 guide blades are the new one. So the analysis and treatment is carried out for this situation. |
