摘要
阐述了长管道输水系统停泵水力过渡过程的特点,结合工程实例,建立了泵出口阀关闭程序的优化模型,并采用遗传算法对模型进行了求解。应用特征线法对事故停泵后的水力过渡过程进行了计算分析,对空气阀和单向调压塔的防护效果进行了数值模拟和比较,提出了相应的水锤防护措施。
The characteristics of pump-stopping hydraulic transient in long-pipe water supply systems are expounded in this paper.Genetic Algorithm method is used by combining examples The optimization model of close program on pump outlet valve is established.Then the pump-stopping hydraulic transients are calculated and analyzed,the protecting effect of the air valve and the one-way surge tank simulated and compared by using the characteristic line method and presenting the protective measures for water hammer.
