机车运行中一旦风泵、辅助发电故障等原因造成风泵不打风或一个风泵不打风,总风缸风压低于规定值,而乘务员又未及时发现,势必会造成列车缓解后充风不足,从而造成列车放飏的恶性事故发生,后果不堪设想。1报警装置改造方案为避免机车放飏这一情况的发生,对我段配属的DF7、DF4型机车进行了技术改造。改造思路为:在总风缸风压降低至正常值以下时,及时进行声音报警,提醒机车乘务人员此时严禁缓解列车制动,
Once the locomotive running wind pump, auxiliary power failure and other causes of the wind pump does not play the wind or a wind pump does not fight the wind, the total wind pressure is lower than the required value, while the crew did not discover in time, will inevitably cause the train to ease after the charge Insufficient, resulting in the train put a vicious accident, the consequences could be disastrous. 1 alarm device transformation program To avoid the locomotive release 飏 this happens, I section of the DF7, DF4 locomotive carried out technological transformation. Reconstruction ideas: in the total air pressure to reduce the cylinder below the normal, timely sound alarm to remind locomotive crew at this time is strictly prohibited to ease the train brake,
