直读铁谱在舰船机械状态监测上的应用

The Application of Direct Reading Ferrography on Marine Machinery Condition Monitoring

采用直读铁谱仪对某型船用机械在用润滑油进行了跟踪监测,选择IS(磨损烈度指数)作为定性分析的判据,利用三线值法对某型船用齿轮箱润滑油样的直读铁谱数据进行处理,并制定出了监测标准。诊断实践证明,直读铁谱监测特征参数IS的选择,是合理准确的,基于三线值法建立的润滑油直读铁谱分析诊断标准,具有良好的实效性,能够较准确地判断和预测船用发动机油润部件的磨损状态和磨损趋势。

This thesis tracks and monitors the under-using lubricant oil of some type of marine machinery by using direct reading ferrograph, chooses Is （wear intensity index） as judgement basis of qualitative analysis, processes direct reading data of some type of marine x lubricant oil samples by using three line value method, and lays out criteria for monitoring. Diagnostic practice proves that the choice of Is, feature parameter of direct reading ferrography monitoring, is reasonable and correct, that analysis and diagnosis criteria of lubricant oil direct reading ferrography set up on the basis of three line value method possesses good effectiveness, which is able to judge and predict the wear condition and wear trend of marine engine lubricating parts comparatively precise.
