1、柴油机油液分析与故障诊断摘要机械设备状态监测及预知维修技术是机械设备现代管理的主要内容。随着现代生产的高速发展,其重要性也H益突显。现代生产的连续性和自动化特点,对机械设备的安全可靠运行提出了更高的要求,耍求机械设备不出现故障,如果有故障隐患能够及时发现,及早采取有效措施,不至于发生大的事故。铁路机车就是具有这一特点的设备,所以开展机车柴油机的故障诊断具有积极的现实意义和经济效益。在此次的毕业设计中,通过查阅大量的文献,从零开始学习油液分析技术的方法、手段和仪器设备等,主要学习了铁谱分析技术和光谱分析技术的优缺点及其技术状况。在对油液分析技术基本了解的情况下,结合实例分析对油液分析做进一步
2、的学习和总结。本文结合机车柴油机润滑系统的特点,根据金屈元素在机车柴油机的分布,运用光谱分析技术对机车柴油机的故障点和故障类型做出判断,并简单分析了光谱分析的元素参考限值的规律;学习对恢谱图像的识别,了解机械的磨损类型,再结合机车柴油机摩擦副的特点,运用铁谱分析技术对机车柴油机的磨损情况做出判断,以期能对机车安全状况做一个止确的判断。关键词:机车柴油机;润滑油;磨损;光谱分析;铁谱分析DieselEngineOilAnalysisAndFaultDiagnosisAbstractMechanicaldeviceconditionmonitoringandpreventativemainte
