高水头船闸输水系统布置及应用

根据国内外及长江科学院建院50多年来对高水头船闸输水系统水力学研究成果,对高水头船闸输水系统布置型式及关键部位体型应用进行了简单介绍,给出了适应不同闸室尺度及水头的等惯性输水系统基本型式和优化闸室内船舶停泊条件以及解决输水系统空化问题的关键部位优化体型,提出了通过阀门底缘掺气解决船闸输水反弧门底缘空化从而简化高水头船闸输水阀门段体型的新思路,以及有望应用于超高水头船闸的具有内外消能系统的新型分散输水系统型式,可提供给有关的科研设计工作者参考。

Pattern and Layout of Crucial Parts of High-head Shiplock’s Water Conveyance System and Applications

The type and layout of crucial parts of high-head shiplock’s water conveyance system is introduced in this paper.The paper is based on research achievements in China and abroad as well as in the Yangtze River Scien-tific Research Institute since its founding half a century ago.The basic pattern of dynamically balanced conveyance system which fits different chamber sizes and water heads is introduced.A new idea of solving the lip cavitation of reversed tainter valve is presented,and a new type of dispersed conveyance system with double energy-dissipation systems (internal stilling pool and external dissipation plate)of higher dissipation efficiency is proposed.This pa-per could offer a reference for researchers and designers in this regard.
