【摘要】 本文介绍我们研制的放射性长距离地下管道检漏仪的工作原理及电路结构、仪器特点、检漏方法和几个主要参数的确定。 仪器的检漏灵敏度可达185kBq(5μCi),定位准确度每km在2.5m之内,适用于口径为15或20cm(6英寸或8英寸)的地下轻油(汽油、煤油和柴油)管道及工业用水管道的检漏。一次检测管道长度可达50km。更多还原

【Abstract】 The instrument introduced provides a means for leak detection of long buried pipelines based on the radioactive tracer technique. The principle, block diagram and performances for the instrument are described The leak-detecting method and the determination of some related parameters are also presented. Leak-detection sensitivity of the instrument is 185 kBq (5μCi). Accuracy for leak localization is within 2.5m (per km). It is suitable for the buried light oil (gasoline, kerosene, diesel oil) and industrial water pipelines with a diameter of 15 or 20cm. The detection length for a single operation reaches up to 50 km.更多还原
