本文阐述了用铁谱技术监测北京型机车柴油机的运行工况。在监测中发现,该型柴油机的铁谱直读数据多次出现突增的异常现象,经调查证实,这些异常情况分别与柴油机润滑系统进水、定修引起污染及进气凸轮表面严重剥离等异常工况有关。监测结果表明,该型机车走行24万 km 入架修时,其柴油机的摩擦副还可以继续使用。
This article describes the use of ferrography to monitor the operation of Beijing locomotive diesel engine operating conditions. During the monitoring, it was found that there was a sudden and sudden anomaly of iron steerable direct read data for this type of diesel engine. After investigation, it was confirmed that these abnormalities were caused by water inflow to the diesel engine lubrication system and caused serious pollution such as dehumidification and serious delamination of the intake cam surface Abnormal conditions related. Monitoring results show that the locomotive running 240,000 km into the repair, the diesel friction pair can continue to use.
