本通用程序中,水击计算采用等时段网格特征线法,阀门启闭为曲线(含直线)变化规律。本程序结构紧凑,需要存贮单元少,使用方便灵活,节约计算时间,成果精度高,只要从键盘上改变输入的数据(程序本身不需更动),便能迅速得到相应情况下,串联管或简单管的水击计算结果。可用于露天钢管、露天钢筋混凝土管、无衬砌隧洞和埋藏式管道(钢板衬砌或钢筋混凝土衬砌或混合衬砌)等组合的串联管,以及各种简单管道的水击计算。特别对于大量不同情况下的水击计算更显优越。
In this general procedure, the water hammer calculation uses the grid characteristic line method of equal time, and the opening and closing of the valve is the variation of the curve (including the straight line). This program has a compact structure, requires a small number of storage units, is easy to use and flexible, saves calculation time, and has a high degree of accuracy. As long as the input data is changed from the keyboard (the program itself does not need to be changed), the corresponding conditions can be quickly obtained. Or simple water hammer calculation results. It can be used for open-end steel pipes, open-air reinforced concrete pipes, unlined tunnels and buried pipes (steel linings or reinforced concrete linings or mixed linings) and other combinations of series pipes, as well as a variety of simple pipe water hammer calculations. Especially for a large number of different cases of water hammer calculations are even more superior.
