Hydraulic Filtration and Component Life Correlation

A new method of correlating hydraulic component contaminant tolerance levels with hydraulic filtration performance has been developed using a cleanliness level chart. The chart provides a means of expressing contamination levels from particle count data. Methods are discussed for deriving component tolerance levels and rating filter elements on the basis of their efficiency characteristics. The correlation achieved enables the designer to establish the performance, reliability, endurance, and ultimate life of the hydraulic equipment.
