铁路运输部14台DF10D型内燃机车,使用仅一年,其牵引电动机大线折损故障共发生28次,严重影响机车正常运用。通过采取的加强大线护托的强度、增加大线护套功能、接头加装护板、改变防震吊链位置、加强机车防震装置检修、加强动轮磨损的检修等措施,大线折损的次数大大减少,提高了经济效益。
14 sets of DF10D diesel locomotives used by the Ministry of Railways only used for one year, causing a total of 28 faults in the traction motor large wire loss, seriously affecting the normal operation of locomotives. By taking measures such as strengthening the strength of the large-sized line guard, adding the function of the large line guard, adding the guard plate to the joint, changing the position of the earthquake-proof hanging chain, strengthening the overhaul of the locomotive anti-vibration device, and overhauling the running wear of the running wheel, Greatly reduce, improve economic efficiency.
