Abstract
The diagnostic merits of microscopic inspection and chemical analysis of metallic debris recovered from lubricating oil filters in a variety of oil-wetted machinery are discussed. The filter cleaning method and how it affects the amount of debris recovered is considered. The significance of representative debris levels and some criteria for establishing these levels are discussed. Abnormal debris accumulations and the corresponding mechanical malfunctions are presented to illustrate how filter debris analysis can be used to diagnose increased component wear in a variety of machinery. Merits for application of this technique for the diagnosis of machinery condition are considered. The report concludes that this method of assessing wear is particularly suited for equipment fitted with fine lubricating oil filters and is recommended as a complement to other methods currently used for machinery condition monitoring.
