乌江银盘船闸输水系统选型研究

银盘船闸设计最大工作水头36.5 m,是目前国内单级水头最高的船闸。为简化过大水头带来的阀门水力学问题,提出了带调节水池和带省水池的船闸方案。通过对三种输水系统型式进行分析比较,结果表明,推荐的省水船闸方案不仅能满足设计和相关使用要求,还可将阀门工作水头减少一半,且船舶过一次闸可节省水量48.6%。

Studies on the Type Selection of the Filling and Emptying System of Yingpan Lock on Wujiang River

Yingpan lock is the highest single level lock at present in China with a working head of 36.5m.This paper presents a regulation tank lock scheme and the water saving lock scheme to settle the valve hydraulics problem caused by high water head.By analyzing and comparing of the general single level lock,the regulation tank lock and the water saving lock,it is concluded that not only the recommended water saving lock can satisfy the design and the correlated operation requirements,reduce the valve work head by a half to simplify value hydraulics problem,but the water saving is possible at least by 48.6% in one ship passage through the lock.
