摘要
介绍了单向调压塔水锤防护的工作原理及计算模型,对单向调压塔水锤防护效果的主要影响因素进行了分析。采用反问题分析方法,以单向调压塔直径、有效水深、补水管直径及水泵出口阀的关闭参数作为决策变量,以单向调压塔的容积最小作为目标函数,建立了单向调压塔尺寸和水泵出口阀关闭程序同时优化的数学模型,并采用改进遗传算法对优化模型进行求解。该优化模型和优化方法在实际工程中的应用表明,数值模拟结果较准确,由此确定的防护措施可靠。
The work theory and mathematic model of one-way surge tank for water hammer protection are expounded. Moreover, the main influence factors for protection effect of one-way surge tank are analyzed. Through the inverse problem analysis method, the optimization model for structural parameters of one-way surge tank and closure program of exit valve of pump, in which the diameter of tank, the effective initial water depth, the diameter of make-up water pipe and the parameters for closure of exit valve of pump were selected as decision variables, was set up and the improved genetic algorithm was adopted to solve it. The application results of the optimization model and method in the actual project show that the numerical simulation result is exact, and the protection measures are reliable.
