目前10L207E型柴油机气缸套拉缸事故较多,严重影响机车的正常运用和检修。有的机车在厂、架修和日常轮修时往往因柴油机缸套拉伤返工多次,有时由于发现不及时造成严重的爆缸事故。有个别拉缸故障甚至返工五、六次最后才能解决。但引起缸套拉伤的一些根本原因仍然没有最后确定。柴油机缸套拉伤是一个很复杂的问题,尤其在当前工业飞跃发展的时期,柴油机单缸功率被迫迅速提高,缸套拉伤已成为当前各国从事柴油机设计、制造、研究者急需解决的课题。10L207E型柴油机虽属中速大功率的二冲程柴油机,制造运用已
At present, 10L207E diesel cylinder cylinder cylinder accident more serious impact on the normal operation and maintenance of locomotives. Some locomotives in the factory, rack repair and routine maintenance often repair due to cylinder liner rework multiple times, and sometimes because of the discovery did not promptly caused a serious explosion cylinder accident. Some individual cylinder failure even rework five or six times before finally can solve. However, some of the root causes of cylinder strain is still not finalized. Diesel cylinder strain is a very complex issue, especially in the current period of rapid industrial development, diesel engine single cylinder power is forced to rapidly increase, cylinder strain has become the current countries engaged in diesel engine design, manufacture, researchers urgently need to solve the problem . Although the 10L207E diesel engine is a medium-speed high-power two-stroke diesel engine, the manufacturing operation has been used
