在动态质量平衡原理的基础上,讨论了判断管道泄漏的方法,分析了影响管道检漏精确性的因素。指出流量计的精度和对管道油品存余量的估计误差是动态质量平衡管道检漏技术中的两个关键因素,也是影响动态质量平衡原理管道检漏精确性的主要因素。提出了提高管道泄漏检测精确性应采取的技术措施。
Based on the principle of dynamic mass balance, the paper discusses the method of judging pipe leakage and analyzes the factors that affect the accuracy of pipeline leak detection. It is pointed out that the accuracy of the flowmeter and the estimated error of the pipeline oil inventory are the two key factors in the dynamic mass balance pipeline leak detection technology and also the main factor affecting the pipeline leak detection accuracy of the dynamic mass balance principle. Proposed to improve the pipeline leak detection accuracy should take technical measures.
