负压波检漏技术在输气管线中的应用

随着我国长距离输气管道的不断增多,管道沿线的泄漏问题日益严重,由此对输气管道泄漏的自动监测和泄漏点的定位就显得尤为重要。本文介绍了应用负压波对管道泄漏进行监测的基本原理和方法,并对定位的基本公式的优化进行了讨论,介绍了更为准确的计算公式。经验证知道经过优化的计算方法具有更高的定位准确度,对管道泄漏自动监测数学计算模型的建立具有一定的指导意义。

APPLICATION OF THE LEAKAGE DETECTION TECHNOLOGY IN GAS PIPELINE

With increase of long-distance gas pipeline in our country,pipe leakage become more and more serious.Automatic monitoring and location of leakage point are particularly important.The paper presents the basic principle and method of monitoring pipeline leakage with suction wave.After discussing optimization of the basic location formulae,it proposed a more accurate computing formula.It is verified that the optimized computing method is more accurate,which is of significance to establishment of the mathematic...
