- 摘要:
- 针对泡沫清管器在清管过程中不能准确判断管道变形，无法清除顽固残余物质，导致后期投放的检测仪器结果不准确，甚至堵塞管道等问题，设计了一种新型、低成本泡沫测径清管器，利用漏磁检测原理在泡沫清管器聚氨酯层中放置磁块，由霍尔元件测量管径变形时的磁场变化，即可得出残余物质的高度、外形等特征来进行预先测径。实现了在管道复杂工况中对管内结垢及变形情况的准确检测，避免了卡堵。以运行过程中的泡沫测径清管器为研究对象，通过ABAQUS 软件仿真模拟其遇到残余物质时的变形情况，结果表明：当发生一定变形时，泡沫测径清管器外层泡沫体密度越大，厚度越薄；内层泡沫体密度越小，厚度越厚，测量得到的位移变化量结果越准确。（图2，表4，参20）
- Abstract:
- A novel and low-cost foam gauging pig was proposed for the issue that the foam pig cannot accurately judge the deformation of the pipeline and remove stubborn residual substances in the pigging process, which may lead to inaccurate results of detection instruments used later or even blockage of the pipeline. Magnetic flux leakage detection principle was used to place magnetic blocks in the polyurethane layer of foam pig, and Hall element was used to measure the change of magnetic field during deformation to obtain the height, form and other characteristics of residual substances for diameter measuring in advance. The design allows the accurate detection of scaling and deformation in the pipeline under complex working conditions to prevent blocking. With the operating foam gauging pig as the research object, ABAQUS software was used to simulate its deformation when encountering residual substances. The results show that when a certain deformation occurs, the larger the density and the thinner the thickness of the foam at the outer layer, or the smaller the density and thicker the foam at the inner layer of the pig, the more accurate the measured displacement variation results will be.
