红外线传感器用来探测热轴时传出的故障信号,往往不是由于轴箱缺陷,而是由于车轮被闸瓦抱死所致。因此,运用、中经常出现差错。传感器对着轴箱,不能探测到轮对的所有区域,所以,最好再研制一种探测制动时闸瓦抱死轮对的专用装置。为了减少地面设施的消耗,这种探测器只需设在有热轴探测器处即可。红外线传感器应能探测因强烈制动或轮对被抱死滑行而过热的直径为350～1200mm的所有车轮。与热轴相类似,须得出两种故障信号:制动时急
Infrared sensors used to detect the thermal axis of the fault signal is often not due to the axle box defects, but because the wheels are locked due to the brake shoe. Therefore, mistakes often occur in the application. Sensor against the axle box can not detect all areas of the wheel alignment, so it is best to develop a special device to detect brake shoe lock wheel pair. In order to reduce the consumption of ground facilities, such detectors only need to be located at the hot-rod detector can be. Infrared sensors should be able to detect all wheels with a diameter of 350-1200 mm that are overheated due to strong braking or wheel-on-slip. Similar to the hot shaft, two fault signals must be drawn: Braking urgency
