摘要
长距离运输管道作为一种经济、有效、环保的运输手段,在液体、气体运输中发挥着独特的优势,而管道泄漏检测是长距离运输管道安全运行的重要保障。通过总结国内外近年来发展起来的管道泄漏检测方法,按运输对象分类介绍了管道运输气体和液体时的检测方法和工作原理,并指出优缺点,探讨了长距离管道运输泄漏检测的发展趋势,指出基于SCADA系统多种检测方法相结合及如何及时、精确地对小泄漏检测和定位是未来的研究方向。
Transportation through long distance conduit used to liquid and gas displays its unique advantage as an economic,effective and environment-protected method,and detection of conduit leakage is the guarantee of its safe work.In the article the method for conduit leakage detection developed in recent year at home and abroad is summed up,the ways and its work principles is introduced by the transported object,whose excellence and shortcoming are indicated;then the development trend is explored of leakage detection of transportation through long distance conduit;it is pointed out that the research direction in the future is to combine multi-method to detect as well as how to exactly detect and orient pretty leakage.
