为揭示竖井贯流泵站停机过程中水力特性变化规律与闸门关闭速度之间的内在联系,以张家港市走马塘江边泵站为研究对象,基于计算流体力学(CFD),通过耦合用户自定义函数(UDF)和动网格技术,对闸门关闭速度分别为30、45和60s时泵站水力过渡过程特性变化规律进行对比分析。结果表明:关机过程中,水泵最大倒转转速、最大倒流流量及达到最大倒流流量的时间均随着闸门关闭时间的增加而增加;而叶轮所受最大水阻力矩和最大轴向力则随着闸门关闭时间的增加而减小,但它们最大值出现时间则随闸门关闭时间的增加而增加。

To reveal the inherent relationship between the hydraulic characteristics changes and the gate closing speed during the shutdown process of the vertical shaft flow pump station, the Zoumatang River side pump station in Zhangjiagang City was taken as the research object. Based on computational fluid dynamics (CFD), by coupling the user-defined function (UDF) and dynamic mesh technology, a comparative analysis was conducted on the variation laws of the hydraulic transient process characteristics of the pumping station when the gate closing speeds were 30, 45, and 60 seconds respectively. The research results indicate that during the shutdown process, the maximum reverse speed, maximum reverse flow rate, and time to reach the maximum reverse flow rate of the water pump all increase with the increase of the gate closing time; The maximum water resistance torque and maximum axial force experienced by the impeller decrease with the increase of gate closing time, but their maximum values appear with the increase of gate closing time.
