铁路应用红外线检测车辆轴温新技术在我国是首创。1973年在上海铁路局南翔列检所试验成功。截止1986年,全国铁路90％的列检所已安装使用800多套红外线轴温探测器,准确率达99％,防止了大量车辆燃轴事故。 一、红外线探测轴温技术的理论与方法 红外线轴温探测是利用车辆运行中发热轴箱所发射红外线的强弱来早期发现热轴故障的一种技术诊断装置。 过去单纯靠列检工人在列车停站后逐个摸轴箱,凭手感来判断热轴故障。无法准确判断。由于准确性差,作业时间长,劳动强度大,往往不易做到早期发现过去燃轴事故每天多达几十起,到处甩车,严重打乱了列车运行图,降低了运输效率,采用红外线检测轴温后,取代
Railway application of infrared detection of vehicle temperature shaft new technology is the first in our country. In 1973 in Shanghai Railway Bureau Nanxiang inspection successfully tested. As of 1986, more than 800 sets of infrared axis temperature detectors have been installed in over 90% of the national railways, with an accuracy rate of 99%, preventing a large number of vehicle flaring accidents. First, the theory and method of infrared detection of shaft temperature technology Infrared detection of shaft temperature is the use of vehicle operation in the heat generated by the axis of the infrared box to detect the early hot-axis failure of a technical diagnostic device. In the past simply rely on column inspection workers in the train stop by touch axle box by hand feel hot shaft fault. Can not accurately judge. Due to poor accuracy, long working hours, labor-intensive, often difficult to do early detection of the past burning shaft accident up to dozens of times a day, thrown around the car, seriously disrupted the train diagram, reducing transport efficiency, the use of infrared detection axis After the temperature, replaced
