加格达奇内燃机务段地处祖国北方,机车运用线路区域全年有7个月是冬季,每年一二月份最低温度达-55℃,日平均温度最低可达-30℃以上;线路多短坡,最大的12.6‰,地势为海拨700～1100米。自1966年筹建内燃段以来,东风型内燃机车已在该地区扎下了根。机车的动力——10L207E柴油机,先后也发生抱缸、拉缸、断轴等重大故障。这些故障的发生,除兄弟段所分拆的原因外,尚有该地区的特殊原因——气候严寒。分折我段柴油机故障,以两大部件——曲轴和缸套为例,从1971年有统计开始到1978年一季度,共裂水套、缸套145个(见表1);断、裂曲轴68根(实际共80根,其中12根无分
Jiagedaqi locomotive depot is located in the northern part of the motherland, locomotives using the line area throughout the year for seven months in winter, the minimum temperature in January and February each year reached -55 ℃, the average daily minimum temperature of -30 ℃ above; short lines Slope, the largest 12.6 ‰, topography 700 ~ 1100 meters above sea level. Since the construction of the internal combustion section in 1966, the Dongfeng diesel locomotive has taken root in the area. Locomotive power - 10L207E diesel engine, has also occurred hold cylinder, pull cylinder, broken shaft and other major failures. In addition to the reasons for the separation of the fraternal section, there are some special reasons for the failure of these areas - the cold climate. A breakdown of my section of diesel engine failure, the two major components - the crankshaft and cylinder liner, for example, from 1971 statistics to the first quarter of 1978, a total of split water jacket, cylinder jacket 145 (see Table 1); broken Crankshaft 68 (the actual total of 80, of which 12 points without points
