水力浮动式升船机水力同步系统数值计算

景洪水力浮动式升船机输水系统采用等惯性原则布置,但由于水流的随机性及输水系统制作、施工误差等原因,在充泄水过程中,各个竖井水位不可避免地存在水位差,不可能完全同步上升和下降,竖井水位的不同步将会增大机械同步系统的受力。论文提出减小竖井间水位差的措施-在竖井底部中隔之间设置连通廊道,并通过数值计算对其设置方式及尺寸进行了优化。

Numerical simulation on synchronous characteristic of the shafts' water levels in Jinghong hydraulic floating ship lift

Water conveyance system and shafts in Jinghong hydraulic floating ship lift are laid out according to the principle of equal inertia.Though,the water levels are different among all shafts during the course of filling and discharging water due to the error of the manufacture and construction,which make it impossible for shaft's water levels to ascend and descend synchronously.The asynchrony of water level change in shafts will lead to the loads of synchrony system complicating.Based on above reasons,the measures to decrease the differences of water levels between each shafts are suggested,that is,to set up equalizing culvert between shafts,which size is optimized by the way of numerical simulative computation.
