摘　　要：由于发动机等机械磨损维修费用很高,因此建立发动机和机械正常运转条件的判断方法,以便监控其运转状态十分必要。测定润滑油中磨损元素含量变化是设备状态监测工作正常与否的一项重要诊断方法。可用于预判早期的机械磨损。污染物元素浓度的显著增加表明润滑油中可能混入外来物质,这些物质会导致设备的磨损或润滑油的衰变降解。研究润滑油中金属和污染物元素含量随时间和工作强度的变化规律,有助于必要时采取相应的措施,避免灾难性事故的发生。综述了润滑油中元素检测的研究现状及进展,梳理了国内外有关标准方法的制修订状况,以期为润滑油中元素检测方法的创新及标准的及时更新提供思路。Since the maintenance cost of the engine and other machinery is very high after mechanical wear,it is necessary to establish a judgment method for the normal operating conditions of the engine and the machinery to monitor its operating state.Determining the change in the content of wear elements in lubricating oil is an important diagnostic method to monitor whether the working state of the equipment is normal,and can be used to predict the early mechanical wear.Early wear can be predicted by comparing the presence or abnormal concentration growth of wear metals with baseline concentration data.The significant increase in the concentration of contaminant elements indicated that the lubricating oil may be mixed with foreign substances,which can cause the wear of equipment or the decay and degradation of the lubricating oil.By capturing the trend in metal and pollutant elements content over time and work intensity,corresponding measures can be taken when necessary to help avoid the occurrence of catastrophic accidents.The research progress of element detection in lubricating oil was reviewed,and the formulation and revision of relevant domestic and international standard methods was sorted out,so as to provide ideas for the innovation of element detection methods and the timely update of standards in lubricating oil.
