摘要
管道运输已成为现代社会不可缺少的组成部分,然而随着管线的增多,由于不可避免的腐蚀、损坏等原因,管道泄漏事故频频发生。泄漏的及时检测与精确定位对防止事故扩大、减少损失至关重要。针对这一问题,采用了修正的动态流量平衡法进行泄漏的检测与报警,提出了用瞬态压力波法和相关时延分析法相结合进行泄漏定位,现场运行和实验验证了其有效性和准确性。
Due to many reasons such as rust and breakage, leak accident happened frequently. It is very essential to detect the leak and locate the position. Aiming at this problem, this article detects the leak by modified dynamic flow equilibrium and provides a method to locate the position which combines the method of instantaneous pressure wave with correlation analyse method. It is proved effective and exact by spot experiment.
