非接触式智能管道通径检测器的设计分析

原油、天然气长输管道建设完工后,必须要进行管径通径检测,其目的在于发现施工过程可能产生的管道异常变形.我们以检测管径原始尺寸完整性为目标,进行管道变形缺陷数字化建模、非接触通径检测器运行过程控制、制造工艺、系统优化等方面的研究,基于激光传感器等技术的结合,研发了新型非接触式智能管道通径检测器,弥补传统的接触式(机械式)...

THE DESIGN AND ANALYSIS OF NON-CONTACT SMART DRIFT DIAMETER DETECTOR FOR PIPELINE

After the construction of crude oil and natural gas long distance pipeline is completed,it is necessary to carry out pipe diameter testing,which aims to find the abnormal deformation of pipeline that may occur in the construction process.We take detecting the original sizes integrity of pipe diameter as the goal,to research on digital modeling of pipe deformation de?fects,non-contact size detector running process control,manufacturing process,system optimization,besides,based on the combination of technologies such as laser sensor,a new type of non-contact smart drift diameter detector is developed,so as to make up for the shortcomings of traditional contact(mechanical)size detector including the data signal distortion caused by unstable running state,easy wear probe and high maintenance cost.Thus the recognition of deformation defects in the inner wall of pipeline is improved as well as data acquisition and the deformation accuracy of size,deformation point location analy?sis,and the excavation operations start under this scheme.The pipeline is repaired in time to eliminate the hidden danger of accidents,so as to provide guarantee for the safe production and operation of oil and gas long-distance pipeline.This paper fo?cuses on the design and analysis of the working principle and structural characteristics of the non-contact intelligent drift di?ameter detector.
