英文摘要:
      Hydraulic ship lift is a new type of ship lift to which China owns the independent intellectual property 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 major technological issues has been displayed in this paper relying on the construction of the world's first Jinghong hydraulic ship lift. A number of breakthroughs have been made in the study of the following technological problems,such as the design theory and method of hydraulic ship lift,hydraulic drive synchronization technology and technology of flow equalization and level stabilization,the chamber tilting mechanisms,theory and technology of anti-tilting under multi-coupling, operation control technology of chamber in unsteady variable speed condition,anti-cavitation technology of high head industrial valves,manufacturing and installation technology of micro gap mechanical synchronous system and so on. The research results have made it possible to operate 70m class hydraulic ship lift steadily,and have laid a solid foundation for the construction of Jinghong ship lift and the popularization and application of this new type of hydraulic ship lift.
