摘要
水力式升船机是我国具有自主知识产权的新型升船机。采用理论研究、物理模型试验、数学模型计算和现场试验与原型观测等研究手段,依托世界首座景洪水力式升船机的建设,针对水力式升船机的设计理论和方法、水力驱动同步技术及流量均衡和液面稳定技术、多重耦合作用下船厢倾斜机理与抗倾理论与技术、非恒定变速条件下船厢运行控制技术、高水头工业阀门防空化技术、微间隙机械同步系统制造安装技术等重大技术难题进行了全面系统研究,取得多项突破性研究成果,实现了70 m级水力式升船机平稳运行,为景洪升船机的建设和水力式新型升船机的推广应用奠定了坚实的基础。
Hydraulic ship lift is a new type of ship lift to which China owns the independent intellectualproperty rights. By means of theoretical research, physical model test, mathematical model calculation,field test and prototype observation, huge amount of comprehensive and systematic research concerning ma-jor technological issues has been displayed in this paper relying on the construction of the world's first Jing-hong hydraulic ship lift. A number of breakthroughs have been made in the study of the following technolog-ical problems,such as the design theory and method of hydraulic ship lift,hydraulic drive synchronizationtechnology and technology of flow equalization and level stabilization,the chamber tilting mechanisms,theo-ry and technology of anti-tilting under multi-coupling, operation control technology of chamber in unsteadyvariable speed condition,anti-cavitation technology of high head industrial valves,manufacturing and instal-lation technology of micro gap mechanical synchronous system and so on. The research results have made itpossible to operate 70 m class hydraulic ship lift steadily,and have laid a solid foundation for the construc-tion of Jinghong ship lift and the popularization and application of this new type of hydraulic ship lift.
