本文是前文之续,在的基础上:①根据停泵水锤基本方程组,结合三种典型的管线布置形式和工程实际,提出了水锤波在“断流空间”边界处反射的概念及数学表达式;②结合前人的工作,进一步系统地论证了停泵——断流水锤计算的特点及其原理,特别是关于空气的注入、排出与压缩等问题;③从理论上论证了H—t座标系统图解法在停泵——断流水锤计算中的应用。
This article is on the basis of the previous article, on the basis of: 1 According to the basic equations of pump-stop water hammer, combined with three typical pipeline layout forms and engineering practices, the concept of reflection of water hammer waves at the “breaking space” boundary is proposed. Mathematical expressions; 2 combined with previous work, further systematically demonstrated the characteristics and principles of the shutdown pump-cutting water hammer calculation, especially with respect to air injection, discharge, and compression; 3 theoretically demonstrated H The application of t-coordinate system graphic method in stopping the pump - calculation of water hammer for water breakage.
