随着电气化铁路在我国迅速发展,国产电力机车技术性能日趋稳定,“长交路、轮乘制”的大力推行,我国目前在机车修理中一直沿用的固定周期预防修理制,已日益暴露出明显的不合理和不科学。固定周期预防修理制,以机车走行公里确定检修周期,机车运行到规定的公里数即进厂或进段按规定的修程范围进行检修。这种“一刀切”的机车检修制度其弊端在于: 1.不考虑机车在不同工况下(不同的线路状态,不同的牵引重量等)机件磨耗的状态,不论部件是否有检修的必要,只根据修程范围而大拆大卸。势必造成人力、物力的极大浪
With the rapid development of electrified railway in our country, the technical performance of domestic electric locomotive is steadily becoming more and more stable. The “long route and round trip system” has been vigorously promoted. The fixed cycle preventive repair system that has been used in locomotive repair all the time has increasingly exposed the obvious Irrational and unscientific. Fixed cycle preventive repair system to locomotive kilometers to determine the maintenance cycle, locomotive running to the required number of kilometers into the plant or into the repair section according to the provisions of the repair range. This “one size fits all” locomotive maintenance system drawbacks are: 1. Regardless of the locomotive in different conditions (different line state, different traction weight, etc.) wear status of the workpiece, regardless of whether the parts necessary for maintenance, only According to the scope of repair large demolition big unload. It is bound to cause great waves of manpower and material resources
