自1971年以来,日本东新潟机务段的机车也逐步采用了新的检修制度。接着,B级定期检修的周期便从6个月延长到15个月(架修——译者注)。普遍认为,6个月定期换油,因油还很洁净就将其排掉是不经济的。但是,由于机车本身质量的改善,虽延长了检修周期,但对于液力传动工作油来说,在没有任何研究和改进的情况下,要延长换油周期,是没有可靠保证的。使定期换油同15个月的定期检修一致起来,一下子就延长到2.5倍。这在只凭经验、靠视觉和听觉来判断的现场上,是有点靠不住的。但是,把定期换油的时间同15个月的B级定期检修一致起来,这是符合现场愿望的。为此,必须考虑消除这些不可靠因素,以求节约油脂和提高机车运用效率。但是,今天在全日本,换油周期都规定为15个月。从下
Since 1971, Japan’s Niigata motorcycle repair section has also gradually adopted a new maintenance system. Then, the period of periodic maintenance of Grade B is extended from 6 months to 15 months. It is generally believed that it is not economical to regularly change oil for 6 months and drain it because the oil is still clean. However, due to the improvement of the quality of the locomotive itself, although the overhaul period is prolonged, there is no credible guarantee for the transmission oil to extend the oil change period without any research and improvement. The regular oil change with 15 months of regular maintenance consistent, suddenly extended to 2.5 times. This is a little unreliable on the scene judged by experience, by sight and hearing. However, it is in line with the wishes of the scene to reconcile the regular oil change with the 15-month regular repair of Class B. To this end, we must consider eliminating these unreliable factors in order to save oil and improve locomotive efficiency. However, throughout Japan today, the oil change intervals are set at 15 months. From below
