摘要:
针对南水北调解台站节制闸液压启闭机启门力不足与纠偏困难的问题，从多个角度深入分析了原因。研究结果表明：解台站节制闸两侧水位差较大，闸门开启时流速较快，导致实际启闭时存在较大的下吸力，闸门实际启闭所需的力远大于原设计值，液压系统管路中存在较大背压，也降低了启闭机的工作效率。基于上述原因，提出了加大启闭力与优化管路设计的解决措施，针对闸门的纠偏困难，改进了阀组设计，确保闸门提升过程的同步要求。研究成果可为同类工程液压式叶调结构优化设计提供参考。
Abstract:
In view of the problems of insufficient opening force and difficulty in rectifying deviation of the hydraulic hoist of the control gate at the mediation station of south-to-north water diversion, the reasons are analyzed from various angles. The research results show that the water level difference on both sides of the control gate at Jietai Station is large, and the flow velocity is fast when the gate is opened, resulting in a large downward suction force when the gate is actually opened and closed. The force required for the actual opening and closing of the gate is far greater than the original design value, and there is a large back pressure in the hydraulic system pipeline, which also reduces the working efficiency of the hoist. Based on the above reasons, the solution measures of increasing the lifting force and optimizing the pipeline design are put forward. Aiming at the difficulty of gate deviation correction, the valve group design is improved to ensure the synchronous requirements of gate lifting process. The research results can provide a reference for the optimization design of hydraulic blade adjusters in similar projects.
