Abstract:

The Pinglu Canal project adopts a multi-tiered water-saving ship lock, which offers advantages in water conservation and adaptability to high water heads. However, the filling and emptying operations are substantially more frequent than those of conventional ship locks. To ensure lockage efficiency, the valve opening and closing speeds must be significantly increased—specifically, the opening speed should be no less than 8 m/min and the closing speed no less than 16 m/min, which are two to four times the conventional rates. This study focuses on the actual fast-acting requirements of the hydraulic hoist in the canal project. A kinematic mathematical model of the hoist is established, and the load characteristics of the working valve are analyzed. A simulation model of the hydraulic system is developed, and three rapid closing oil-filling schemes—accumulator oil filling, high-level tank oil filling, and pump-direct oil filling—are comprehensively compared and evaluated. Prototype tests are conducted to validate the simulation results. The results indicate that, considering dynamic refueling performance, technological maturity, structural stability, and reliability, the high-level tank scheme is the most reasonable. The prototype test results are generally consistent with the simulation predictions, with a maximum relative error of approximately 4.1%. The measured maximum opening speed is about 8.2 m/min, and the maximum closing speed is about 16.1 m/min. The designed fast hydraulic hoist exhibits good dynamic control performance.

摘要:

平陆运河工程采用多梯级省水船闸,具备省水、适应高水头等优点,同时灌泄水步骤较普通船闸显著增加,为保证过闸效率,须大幅提高阀门启闭速度(启门速度不低于8 m/min,闭门速度不低于16 m/min,达到常规速度的2~4倍)。基于该运河工程液压启闭机实际快速启闭需求,建立启闭机运动学数学模型,分析工作阀门的负载特性,建立启闭机液压系统仿真模型,综合对比分析蓄能器补油、高位油箱补油、启泵补油三种闭门快速补油方案,并进行样机试验验证。结果表明:综合考虑补油动态性能、技术成熟度、结构稳定可靠性等,采用高位油箱补油方案最为合理;样机试验测试与仿真结果趋势基本保持一致,其最大相对误差约4.1%,最大启门速度约8.2 m/min,最大闭门速度约16.1 m/min。所设计的快速液压启闭机具有良好的动态控制性能。
