长距离输水管道的水力计算一直是困扰水利和市政设计院的问题。通常在长距离输水过程中,由于水泵和阀门的操作会引发压力波动从而产生水锤。水锤现象的发生对管道会产生直接和潜在的破坏,研究水锤的发生过程和设置防护设备是输水管道设计环节中的重要工作。对于水锤计算过程中的一些特性分析和现象观察,Hammer是一个理想的易用工具。 Hydraulic calculation of long-distance pipelines has long been a problem for water conservancy and municipal design institutes. Often during long-distance water transfer, water hammer occurs due to pressure fluctuations caused by the operation of pumps and valves. The occurrence of water hammer phenomenon will directly and potentially damage the pipeline. Studying the occurrence of water hammer and setting up protective equipment are important work in the design of water pipeline. Hammer is an ideal, easy-to-use tool for characterizing and observing water hammer calculations.
