前言多年来,对红外线轴温探测器探照点位置的调校及检查,都是用静态的方法在模拟货车转8A转向架轴箱上进行的。常有校试完毕后,并不能很好地发现车辆热轴故障,而造成漏报,究其原因有: ①传统的静态测试红外探头与轴箱被测位置的方法,不能满足车辆运行时的动态工况需要,运行中的轴箱有效热辐射能量未完全进入红外探头的视角。②厂家给出的安装技术尺寸范围较大,使用人员在范围内随意性增大,降低了探测的准确性。③HTK-391型红外二代机探头装置设在轨枕两端头内的枕距间,其工作环境非常
Foreword Over the years, the calibration and inspection of the location of the search points for infrared axis temperature detectors have been carried out on a quasi-van truck steering system 8A with a static method. Often after the completion of the test, and can not be very good to find the vehicle hot axle failure, resulting in underreporting, the reasons are: ① traditional static test infrared probe and the axle box measured location of the method can not meet the vehicle’s operation Dynamic operating conditions require that the effective heat radiation energy of the axlebox in operation does not fully enter the view of the infrared probe. ② manufacturers to install a larger range of technical dimensions, the use of personnel within the random increase, reducing the detection accuracy. ③ HTK-391-type infrared second-generation probe device is located in both ends of sleepers pillow distance, the working environment is very
