负压波定位理论在输油管道泄漏监测系统中应用

Application of the negative pressure wave theory in the leak-detecting system of trans- porting-oil pipe

本文主要讲述了负压波理论在输油管道泄漏监测系统的具体应用情况;分析了采用负压波理论进行泄漏定位的过程中时间差的求解问题,提出了三种求取时间差的方法。通过负压波理论的定位公式以及时间差对泄漏点进行定位。

This article narrated the application of the negative pressure wave method in the leak detecting system of transporting-oil pipe. It analyzed the acquirement of time difference in the course of leak point orientating using the negative pressure wave theory. And we bring forward three kind methods to acquire the time difference. According to the time difference and the orientating formula based on the negative pressure wave theory, we can calculate the leak point.
