SS4改型电力机车制动机过量供给故障分析及处理

因列车制动管过量供给,致使列车发生自然制动、车辆闸瓦过热冒烟被拦停;制动管压力过高造成制动软管爆破而使列车紧急停车的事故时有发生。介绍了SS4改型机车发生过量供给的原因和危害,提出了发生过量供给后列车维持运行的解决方案:转空气位操纵、手动控制压缩机工作、频繁施行常用制动;利用列车高速运行或停车机会消除过量供给。对提高机车司机的业务水平,确保铁路运输安全畅通具有十分重要的意义。

Analysis of the Brake Failure in Type-SS4 Modified Locomotives and Treatment of the Excessive Supplies

When the train brake block becomes too hot and smokes because of the excessive supplies of the train brake tube,the train will be braked naturally and be stopped.The too high pressure of the braking tube often results in the cracking of the braking hose,as a result of which the train is frequently emergency-braked.The causes and hazards of the occurrence of the excessive supplies of Type-SS4 modified locomotives are described and analyzed in the paper,with solutions presented to keep the train running after the occurrence of the excessive supplies,such as inverting the manipulation of air spaces,manually controlling the operation of the compressor,frequently applying the usual braking system,and eliminating the excessive supplies when the high-speed train is running or keeps standing.It＇s of great significance in improving the driver＇s professional level,and ensuring the safety and the smooth operation of the railway.
