AN EXPERIMENTAL EVALUATION OF THE SINTERED TYPE FILTER MEDIA

Pagination or Media Count:
IT WAS CONCLUDED THAT THE MAXIMUM PARTICLE SIZE AND THE CONTAMINANT CAPACITY TEST GAVE THE MOST RELIABLE AND REPRODUCIBLE INDICATION OF AN ACTUAL PERFORMANCE OF A FILTER ELEMENT IN A HYDRAULIC SYSTEM. Results of these tests correlated well with the bubble test results in most cases. The bubble test should not be attempted on dirty filters or filters that have not been completely cleaned, since some o the pore openings may be blocked. The circuit used in the performance test is believed to simulate a typical hydraulic system. The size range of the actual contaminant introduced during the test should extend well above and below the nominal pore size of the element. Test reslts indicate that the sinteredtype element has a greater contaminant capacity and a greater resistance to high temperature and pressure fluctuations. The differential pressure required to rupture these elements is significantly higher than the differential pressure required to rupture other filter media. The size of the particles passing through the filter elements decreased slightly or remained constant up to the contaminant capacity of the element. Author
