| Abstract: | It had been detected some leaved problems because of design and installation of Lijiaxia hydropower station's 4# turbo generator, and this conduced to the fixed anti-leakage ring's weld joint breakage under turbo generator's rotator, as well as reflected to the jointed bolt breadage of additional air valve's base welding line flange, the paper makes an analysis and summarize about the discovered unreasonable phenomenon in the extended overhaul process, and adopts some relevant improving measurements, in order to improve the safe operation of the units, as well as establish a favorable foundation for the unit's eligibility. |
