| 铁谱技术是以机械摩擦副的磨损为基本出发点，借助于铁谱仪把液压油中的磨损颗粒和其他污染颗粒分离出来，并制成铁谱片，然后置于铁谱显微镜或扫描电子显微镜下进行观察，或按尺寸大小依次沉积在玻璃管内，应用光学方法进行定量检测。通过以上分析，可以准确地获得系统内有关磨损方面的重要信息。 Ferrography technology is based on the wear of mechanical friction pairs. With the aid of Ferrograph, the wear particles and other contaminated particles in hydraulic oil are separated and made into Ferrograph. Then, they are observed under Ferrograph microscope or scanning electron microscope, or deposited in glass tube according to the size, and quantitatively detected by optical method. Through the above analysis, the important information about wear in the system can be obtained accurately. 据此进一步研究磨损现象，监测磨损状态，诊断故障前兆，最后作出系统失效预报。铁谱技术能有效地应用于工程机械液压系统油液污染程度的检测，监控，磨损过程的分析和故障诊断，并且具有直观、准确、信息多等优点。因此，他已成为对机械工程液压系统故障进行诊断分析的有力工具。 According to this, further study the wear phenomenon, monitor the wear state, diagnose the fault precursor, and finally make the system failure prediction. Ferrography technology can be effectively applied to the detection, monitoring, wear process analysis and fault diagnosis of the hydraulic system of construction machinery, and has the advantages of intuitionistic, accurate and informative. Therefore, it has become a powerful tool for the diagnosis and analysis of mechanical engineering hydraulic system faults. |
