摘要
在国内 ,负压波检漏技术被广泛用于液体管线泄漏的诊断。在应用过程中 ,假设条件和涉及到的不确定因素较多。由于涉及到的任何一个因素有误都可能导致不正确的结果 ,因而将该技术与泄漏诊断的其他技术结合起来进行综合研究 ,才能更准确地确定出泄漏的位置。负压波检漏技术具有三大发展趋势 :第一 ,与其他技术一同使用 ,从而更好地解决相关的定位问题 ;第二 ,强化对负压波检漏技术的研究 ,定性研究负压波传播模型可以更好地确定泄漏发生的时间 ;第三 ,对负压波检漏技术的研究从定性到定量 ,定量的分析结果可以用于推测管线泄漏量和泄漏位置。
The negative pressure wave techniques are widely used in China to diagnose the leakage in liquid pipelines.Many assumptive and uncertain factors are often involved in the process of leak detection,which can easily result in errors,even if only one of the factors is not correctly assumed or known.Thus the negative pressure wave techniques should be integrated with other dating techniques to drive a more accurate leak location.Additionally,the development trends of negative pressure wave techniques are as follows:First,negative pressure wave detection techniques will be integrated with other compatible detection techniques and modern signal processing methods to solve the complex problems encountered in leak detection.Second,studies of negative pressure wave techniques have advanced to a new stage.The deductions on propagation mechanism of negative pressure wave have been successfully applied to determine leaks qualitatively.Third,analysis on negative pressure wave detection techniques will be made from a quantitative point of view.The quantitative data have been used to deduce leak amounts and location.
