把通过分析润滑油中的磨耗粉来诊断机器的状态作为研究的一种方法是以发生于装车柴油机连杆大端轴承烧损这一事故为例,研究了预测柴油机故障的可能性。由磨耗粉分析的结果确认,从故障发生前的2次采油样(约每隔2周的时间内定期采油样,测定油量为1ml)中,轴承显示出了异常征兆:10μm以上的有色金属磨耗粒子数急剧增加,其数量在10个以上。另外,数十例轴承在无异常的情况时,在同一条件下测定的润滑油中10μm以上的
To diagnose the condition of the machine by analyzing the wear powder in the lubricating oil is taken as an example to study the possibility of predicting the breakdown of the diesel engine by taking an example of the accident occurred in the burning of the large-end bearing of the diesel engine connecting rod. As a result of the abrasion powder analysis, it was confirmed that the bearing showed anomalous symptoms from the second oil recovery sample before the failure occurred (the regular oil recovery sample was measured every two weeks and the measured oil amount was 1 ml): the non-ferrous metals having a size of 10 μm or more The number of wear particles increased sharply, the number of more than 10. In addition, dozens of bearings in the absence of abnormal circumstances, under the same conditions measured in the lubricating oil 10μm or more
