基于负压波的管道泄漏诊断

A METHOD OF LEAK DIAGNOSIS BASED ON NEGATIVE WAVE PROPAGATION IN PIPELINE

摘要: 本文介绍用波敏法进行管道泄漏诊断的原理和试验结果，波敏法是基于压力波传播规律，并采用相关分析技术对从管道两端所采集到的压力信号进行处理以实现泄漏检测与定位的一种诊断方法，由于不需要流量信号，且对负荷扰动具有较强的抗干扰能力，因而具有较大的实用价值．

Abstract: The principle and test results of wavealert method are presented in this paper.It is a method of leak diagnosis based on negative wave propagation with correlation analysis.It only requires pressure signals acquired from inlet and outlet of pipeline,and is capable of rejecting the effect of load disturbances on leak detection,so that is of great value to practice.
