by analyzing the damage and leakage of the wicket gate seal for baishan hydropower plant, it is presented that the main reason of leakage is applying nylon bearing bush.
the application of such technology will play a great role in reducing the leakage of turbine wicket gate and saving energy.
此项技术如得到应用并获得成功,将对减少导叶漏水、节省能源起到显着作用。
it is highly important to the efficiency guide line of the whole hydraulic equipment unit and to the unit runs safety and steadily that the wicket gate end clearance of the hydraulic turbine.
水轮机的导叶端面间隙对整个水轮发电机组的效率指标及安全稳定运行有着重要影响。
to decrease the leakage of full closed wicket gate of reaction turbine is an important subject of improving the constructional characteristic of water turbine.
减少反击式水轮机导叶全关后的漏水量是改善水轮机结构性能的重要课题之一。
at wicket gate a dog is heard to bark.
柴门闻犬吠,风雪夜归人。
besides, a notable vortex rope and a reverse flow structure exist in the draft tube in smaller wicket gate openings, which can easily lead to the instability in operation of the pump-turbine.
