摘要
封头参数检测是确保封头质量,消除压力容器安全隐患的重要措施。传统接触式的封头检测方法存在着诸多问题,为此,提出一种利用激光非接触式扫描进行封头参数检测的方法。该方法利用支撑杆将激光扫描检测装置定位于封头端面,通过距离检测与电机的旋转扫描,完成封头形状参数的检测。介绍该方法原理、操作过程,分析该方法的误差。最后,对该方法进行实际测试验证。结果表明,该方法可以进行封头形状参数的准确测量,误差同理论分析相符。
The detection of head parameters is an important way to ensure the quality of head and eliminate the potential safe -ty hazard of pressure vessel .To solve the existing problems of traditional contact detection method of pressure vessel head , a method of head parameters detection using non-contact laser scanning was proposed , in which the laser scanning detection de-vice is located at the end surface of head with supporting poles , and the detection of head shape parameters can be realized through the distance measurement and rotating scanning of electric motor .The principle and operation steps of this method were introduced , then the error of this method was analyzed , and the actual testing validation was carried out .The results showed that the method can be used to detect the head shape parameters accurately , and the error is in accord with the theo-retical analysis .
