一、红外线轴温探测器工作原理 铁路列车车辆在运行过程中,由于速度和载重等关系,轮轴和轴瓦在不断互相摩擦而产生温升,对少数轮轴轴瓦等存在着不良因素而温度升高,造成燃轴事故。 红外线轴温探测器(见图1)是用来专门探测发现在运行中列车的各个轴箱的热辐射即“红外线”,红外线辐射是同于物体内部分子热运动而产生的。红外线和可见光相似,是直线传播,能够用特制的透镜进行
First, the infrared axis temperature detector working principle Railway train vehicles in the operation process, due to the relationship between speed and load, the shaft and the bearing in friction with each other and produce temperature rise, a few axle bushings and other adverse factors exist and the temperature increases, Cause combustion shaft accident. Infrared axis temperature detector (see Figure 1) is used to specifically detect the heat radiation that is found in each axle box of the train in operation, ie “infrared light”. Infrared radiation is generated by the same thermal motion as that of the molecules inside the object. Infrared and visible light is similar, is a straight line, can be made with a special lens
