摘要:
地下压力管道敷设在地下具有隐蔽性,由于管网材料、施工、使用、运行、外部环境、管理等因素,造成管网漏损现象非常普遍。查找压力管道漏点位置主要采用听漏判别法,通过对不同漏点的声音进行判别,从而确定漏点的位置。该文通过设计一套压力管道漏损探测系统,在管道组不同子管路上模拟漏水点,且在子管路上迅速切换,以分辨和掌握不同管材、管径、流速的漏点声音特质;通过各种阀门的开闭来模拟漏水点;最后通过对压力管道漏损量计算,检验系统的可行性。
Abstract:
Underground pressure pipes are concealed and laid underground. Due to factors such as pipe network materials, construction, use, operation, external environment, management, etc., pipe network leakage is very common. For finding the leak point of the pressure pipeline, the leak detection method is mainly used to discriminate the sound of different leak points to determine the position of the leak point. In this paper, by designing a leak detection system for pressure pipelines of the same type of actual engineering projects, the leakage points are simulated simultaneously in different sub-pipelines of the pipeline group, and the sub-pipelines are quickly switched to distinguish and grasp the different pipe materials, pipe diameters and flow rates. Leak point sound characteristics; simulate the leak point through the opening and closing of various valves; finally, calculate the leakage of the pressure pipeline to check the feasibility of the system.
