| Abstract: | Owing to the fact that pressure fluctuation of hydraulic turbine working seals happens frequently while large hydraulic generators of Gezhouba Hydropower Station and several other hydropower stations are operating.It is proposed that in period of small-scale repairing,adjusting the water level degree of hydraulic turbine seal rings and local padded are adopted to solve the phenomenon of pressure fluctuation.Practice proves that the method is valid for engineering projects,and offers safe operation assurance... |
