1977年由铁道部科技委主持召开的科技规划会上,曾谈到我国目前内燃机车质量不高,性能不可靠,特别是漏水、漏油、漏气严重,影响内燃机车正常使用。参加会议的有关科研单位,机车制造厂、修理厂以及内燃机务段一致认为,橡胶配件质量差是“三漏”的重要原因。根据调查,国内目前生产的内燃机车橡胶配件存在的问题很多,与国外进口机车所用橡胶配件比较,质量差距很大。目前国内生产的机车的架修期规定为15—18万公里,橡胶件虽
In 1977, Science and Technology Planning Conference chaired by the Ministry of Science and Technology of the Ministry of Railways had mentioned that the quality of diesel locomotives in China is not high at present and its performance is not reliable. In particular, water leakage, oil spills and serious gas leaks affect the normal use of diesel locomotives. The scientific research institutes participating in the conference, the locomotive manufacturing plant, the repair shop and the internal combustion engine segment all agreed that the poor quality of the rubber parts is an important reason for “three leaks”. According to the survey, the domestic production of diesel locomotive rubber parts there are many problems, and foreign imported locomotive used rubber parts, the quality gap is very large. At present, the domestic production of locomotive repair period of 15-18 million kilometers, although the rubber pieces
