紧张、繁忙的铁路运输,安全第一的指导思想,对机车质量提出了更高的要求。机车质量的高与低取决于基本技术状态,而基本技术状态一是靠各级修理的合理按排与实施,二是靠使用保养。哈分局地处全局中枢,由于机务部门广大职工的奋力拚搏,基本上满足了运输需要,确保了机车供应。但是,机车质量仍处于波动状态,质量故障末得到很好控制,既影响运输任务,又危及行车安全。究其原因,在客观上有机车构造上的先天不足、机车老化、厂修质量不过关、机车超负荷使用、材料配件供应紧张等等;
Tense and busy railway transport, safety first guiding ideology, put forward higher requirements on locomotive quality. High and low locomotive quality depends on the basic state of technology, and the basic technical status of a reasonable by the various levels of repair and implementation, and the second is to use maintenance. Harbin branch is located in the global center, due to the extensive efforts of the maintenance department workers, basically meet the transport needs, to ensure the supply of locomotives. However, the quality of the locomotive is still in a state of fluctuation, and the quality faults are well controlled at the end, which not only affects the transportation tasks but also endangers the driving safety. The reason for this is that there are inherent deficiencies in locomotive construction, the aging of locomotives, the quality of factory repairs, the overloading of locomotives and the tight supply of materials and accessories.
