水轮机气蚀损坏是我国水电站运行经常遇到的问题。研究减轻气蚀损坏,以延长大修周期,提高水电机组利用率,仍然是今后需要进行科学研究的重要课题。
Cavitation erosion of hydro-turbine is a problem often encountered in hydropower station operation in China. Research on mitigating cavitation damage to prolong the overhaul period and improve the utilization rate of hydropower units will remain an important issue that needs to be studied in the future.
