本文介绍了一种利用负压波在石油输送管道中的传播速度来分析判定管道泄漏工况的动态电子监视系统.通过具体应用实例进一步介绍了该泄漏监视系统的工作原理及现场应用情况.由压力、流量变化曲线判断管道泄漏工况,并通过工况点引起的负压波分别向首站和末站传播的时间来确定泄漏点位置,实现了安全输油的目的.“,”This paper introduces a kind of make using of the negative pressure wave oil pipeline in the propagation of the speed to the analysis of the dynamic conditions to judge pipe leakage electronic surveillance system. By an application example this paper introduces this leak monitoring system and working principle of the field application. By pressure, flow curve judgment pipe leakage conditions, and through the condition caused by negative pressure wave points respectively at the end of the year and to stand the time of transmission to determine the leak points, and achieve the safe oil purpose.
