Smartball自漂流式检漏系统由主机、智能球、声音接收器(SBR)及接收器(AGM)组成,工作原理是利用其内部集成的声音传感器收集管道泄漏时产生的低频声波信号,该信号大小与泄漏处的泄漏流速大小成比例。通过内部集成的计时器和速度计测算出的数据,可以确定缺陷的位置,在管道上方放置管道内置的GPS模块的AGM,可有效提高泄漏的定位精度。2009年9月15日,于花格线中灶火-格尔木段进行了Smartball的现场应用,在距Smartball发射端70499m处发现1个泄漏孔,泄漏量为0.5L/min,将探测结果与管道泄漏点的实际位置进行核对,定位误差仅为2m。实践证明,该系统能够有效地对管道中存在的微小泄漏进行检测和定位,具有适应性强、检漏精度高、使用方便、效率高等特点。
Smartball self-drifting leak detection system consists of host, smart ball, sound receiver (SBR) and receiver (AGM) composition, the working principle is the use of its internal integrated sound sensor to collect low-frequency sound wave signal generated when the pipeline leaks, Proportional to the size of the leak at the leak. Through the internal integrated timer and speedometer measured data to determine the location of defects in the pipe above the pipe built GPS module AGM, which can effectively improve the positioning accuracy of the leak. September 15, 2009, in the grid line stove fire - Golmud paragraph Smartball field applications at the Smartball launch side 70499m Department found a leak hole, the amount of leakage of 0.5L / min, the detection results and pipeline leak Check the actual location of the point, positioning error of only 2m. Practice has proved that the system can effectively detect and locate tiny leaks in the pipeline, and has the advantages of strong adaptability, high leak detection precision, convenient use and high efficiency.
