Analiza realnih in testnih delcev v hidravličnih filtrih

Kunavar, Matej (author), Majdič, Franc (mentor)

Filtracija olja in obraba hidravličnih komponent je odvisna od lastnosti delcev. Trenutno znanje o delcih še ne zadostuje da bi natančno določili njihov vpliv. Z namenom analize realnih in testnih delcev, smo razvili postopek pridobivanja realnih delcev iz hidravličnih filtrov. Iz obojih smo izdelali preparate za mikroskopiranje z optičnim in elektronskim mikroskopom, ki se je izkazal za primernejšega. Analiza je pokazala da se delci med seboj razlikujejo po obliki in v materialnih lastnostih. Prav tako je pokazala, da imajo efektivni sloji različen vpliv na filtracijo olja.

• Title: Analysis of real and test particles in hydraulic filters

Abstract

Oil filtration and wear of hydraulic components depend on the particle properties. Current knowledge about particles is not sufficient to determine their effects precisely. With the aim of analyzing real and test particles, we have developed a method for extracting real particles from hydraulic filters. From both we have produced preparations for microscopy with optical and electron microscopes, which have proven to be better. The analysis showed differences in the particle shape and their material properties. They also showed that separate filter layers have different effects on oil filtration.
