摘要
研究在水平管道中当泄漏和阀动作同时发生时，泵的出口流量和压力的变化。利用VB软件根据泄漏和阀动作水力瞬变的数学模型，编写程序，以设定的水平管道为例，分析因泄漏和阀动作引起的水力瞬变特性，从而为区分泄漏和泄漏与阀动作共存时水力瞬变特性奠定基础。
The variation of the flow rate and the head loss of the pump discharge are studied in the paper when the leak and the operating valve happened simultaneously. Based on VB software and the mathematical model of the leak and the operating valve, the procedure are written. The characteristic of hydraulic transient is analyzed in order to find the difference of the characteristic of the leak and the characteristic of the leak and the operating valve by setting the horizontal pipeline as an example.
