摘要:
针对南水北调邳州站叶片过调问题，从液压式叶片调节系统的工作原理出发，构建针阀和主配压阀复位运动的数学模型，基于Matlab Simulink仿真，揭示了针阀和主配压阀复位运动规律。研究结果表明，邳州泵站叶片调节系统的针阀和主配压阀复位存在1.4 s左右的时间滞后，此是导致叶片过调的主要原因。结合邳州泵站现状，提出了增加限位调整螺母，预留滞后时间差，适当增大弹簧刚度系数的解决措施，研究成果可为液压式叶调结构优化设计和同类工程问题的解决提供重要参考。
Abstract:
Aiming at the problem of blade over-adjustment in Pizhou Station of the South-to-North Water Diversion Project, according to the working principle of the hydraulic blade adjustment system, mathematical models of the reset movement of the needle valve and the main pressure distribution valve are constructed. Based on Matlab Simulink simulation, the reset motion law of needle valve and main pressure distribution valve is revealed. The results show that there is a time lag of about 1.4s in the reset of the needle valve and the main pressure distributing valve of the vane adjustment system of Pizhou Pumping Station, which is the main reason for the overadjustment of the vane. Combined with the current situation of Pizhou Pumping Station, this paper proposes solutions which is that increase the limit adjustment nut, reserve the lag time difference, and appropriately increase the spring stiffness coefficient. The research results will provide an important reference for the optimization design of the hydraulic blade adjustment structure and the solution of similar problems in similar projects.
