针对某长距离输水工程的特点,应用水锤基本理论和特征线方法,对系统事故停泵水力过渡过程进行了数值计算,对加设单向调压塔水锤防护措施进行了计算分析,从计算结果看,加装单向调压塔能较好的避免水柱分离的发生。根据计算分析,采用加设多处单向调压塔作为本工程的水锤防护措施,对该工程是安全实用的,所得出的结论对长距离输水系统的水锤防护具有一定的实践意义。
Aiming at the characteristics of a long distance water conveyance project, the basic theory of water hammer and the characteristic line method were used to calculate the hydraulic transition process of the system accident pump. The calculation and analysis of the water hammer protection measures of the unidirectional pressure regulating tower was carried out. From the calculation results, the installation of one-way pressure regulating tower can better avoid the occurrence of water column separation. According to the calculation and analysis, it is safe and practical to add multiple unidirectional pressure regulating towers as the water hammer protection measures of the project, and the conclusions drawn are of practical significance to the water hammer protection of the long distance water delivery system .
