采用光谱分析方法和铁谱分析方法对某6缸高功率密度柴油台架设计验证过程中的故障进行分析。通过对油样的光谱分析,确定磨损金属元素Al、Fe、Cr、Mn及Cu、Pb、Ni存在相关性。对光谱分析发现的Al元素质量分数突然增大的某油样进行铁谱分析,发现油样中存在大块铝颗粒;结合发动机摩擦副材料选用情况,确定活塞存在故障,整机拆解进一步验证了这一结果。采用光谱和铁谱相结合的分析方法,提高了基于油液分析方法诊断故障的准确性和可行性,有助于柴油机故障位置的准确确定。
採用光譜分析方法和鐵譜分析方法對某6缸高功率密度柴油檯架設計驗證過程中的故障進行分析。通過對油樣的光譜分析,確定磨損金屬元素Al、Fe、Cr、Mn及Cu、Pb、Ni存在相關性。對光譜分析髮現的Al元素質量分數突然增大的某油樣進行鐵譜分析,髮現油樣中存在大塊鋁顆粒;結閤髮動機摩抆副材料選用情況,確定活塞存在故障,整機拆解進一步驗證瞭這一結果。採用光譜和鐵譜相結閤的分析方法,提高瞭基于油液分析方法診斷故障的準確性和可行性,有助于柴油機故障位置的準確確定。

The fault of a 6-cylinder high power density diesel engine during the bench verification of design was ana-lyzed based on spectrum and ferrography methods.The correlation of the worn metal elements of Al,Fe,Cr and Mn was de-termined,as well as worn metal elements of Cu,Pb and Ni.The oil sample in which the Al mass fraction was increased ab-ruptly by spectrum analysis was analyzed with the ferrography method,the large aluminum particles were found in the oil sample.With reference to the designed material of the engine friction pairs,the piston fault was determined and was further verified by the disassembly of engine.The accuracy and feasibility of fault diagnosis by oil analysis is improved with spec-trum and ferrography methods,it is helpful for the accurate determination of the fault location of diesel engine.
