本文通过对压力管道渗漏振源传播特性的实验研究与理论分析,给出了利用渗漏响应的谱特征、相关性以及传播衰减特性来识别渗漏和确定漏点位置的几个基本方法,其中着重介绍了弹性波动相关检漏的原理及复杂管网中渗漏振源的相关辨识及定位方法。
Based on the experimental and theoretical analysis of the propagation characteristics of the pressure pipeline leakage source, this paper presents some basic methods to identify the leakage and determine the location of the leakage by using the spectral characteristics, correlation and propagation attenuation characteristics of the leakage response. The principle of elastic wave-related leak detection and the related identification and positioning method of leakage source in complex pipe network are emphatically introduced.
