Analysis on Positioning System of Slurry Pipeline Leak Detection for Long Distance Transportation
XU Peng-kui · Nonferrous Metals Design · 2012
For sake of detecting on pipeline leak for long-distance slurry transportation and positioning,the leak detecting and locating methods for slurry pipeline at home and abroad and its application situation were briefly analyzed.Research highlight on practical application of negative pressure wave leak detection and positioning algorithm was given.Especially in-deep investigation and analysis on time difference of pressure inflection point at first station,pressure monitoring station and end station required in negative pressure wave positioning formula,that is inflection point finding of pressure drop at each station,were carried out.On that basis,one set of leak detection system based on SCADA system was designed.Main assembly structure of the system,function of all parts and data treatment principle were provided.
