船舶管路系统泄漏定位实验研究

摘要

船舶管路是船舶的重要组成部分,由于外部环境的恶劣,管路泄漏不可避免,对管路泄漏的监测定位尤为重要,针对这个问题,本文分析了管路泄漏机理,搭建了船舶管路泄漏定位实验台,选用小波变换对采集信号进行滤波处理,进而导入流体网络模型中,选用了±3 kPa作为阈值判定管路泄漏,最后运用压力梯度法进行泄漏定位,完成了船舶管路的泄漏定位检测.%Pipe is an important part of the ship, the pipeline leakage is inevitable due to the bad external environment. So the pipeline leakage monitoring and positioning is particularly important. The ship pipeline leakage localizationexperi-ment table is built based on the analysis of the pipeline leakage mechanism. Then the wavelet transform is used to filter the signal noise, and the signal that is filtered is imported in fluid network model. The model proves that ±3 kPa could be a threshold to determine whether the pipeline leakage or not. Finally pressure gradient method is used to locate the location that complete the aim of pipeline leakage detection and location.
