| Abstract: | The key effect of the wearing ring of hydraulic turbine is to reduce the leakage from the running clearance of the runner， i.e. once the ring is damaged， the safe operation of the unit is to be impacted， and then， it is even to lead to an accident. The causation analysis and the treatment scheme made for the burn-out accident of the stationary wearing ring of Francis turbine are described herein， and then the main quality control points for the operation safety of the turbine are summarized as well， so as to provide references for the accident treatment of the similar hydraulic turbine unit. |
