摘要
以水电站运行的大量实例分析了泥沙磨蚀和空化在停机备用时对活动导叶的危害,指出现有快速闸门已不能满足水轮机调峰调频的需要,性能和作用更优的圆筒阀在引进应用取得成功后,在水电站设计选型中有着广阔的发展前景。
Taking some hydropower stations as examples, the paper analyzes the harmfulness of abrasion and cavitation caused by the water leakage during outage. The present stop gate is not able to meet the needs of the load peaking and the frequency modulation. Since the cylinder valve was imported and successfully applied, it had been indicated that the cylinder valves have a vast range of prospects for the design of hydropower station and the type selection of equipment.
