发布时间：2018-10-19 20:46
【摘要】：在长距离有压管道输水系统中,为了避免事故停泵水锤威胁输水系统的安全,有必要对有压管道中的水锤进行准确的模拟。根据水锤基本理论,基于特征线法对实际长距离输水工程发生事故停泵后的水力过渡过程进行计算分析,讨论了泵出口阀关闭程序,沿线设置的空气阀和调压塔等措施对水锤防护效果的影响,最后提出相应的优化建议。
[Abstract]:In order to avoid water hammer from stopping pump from threatening the safety of water conveyance system in long distance pressurized pipeline it is necessary to simulate the water hammer in pressure pipeline accurately. According to the basic theory of water hammer, based on the characteristic line method, the hydraulic transition process of actual long-distance water conveyance project after the accident of stopping pump is calculated and analyzed, and the closing procedure of pump outlet valve is discussed. The influence of the air valve and pressure regulating tower along the line on the protection effect of water hammer is discussed, and the corresponding optimization suggestions are put forward.
