Relating quality, capacity and energy consumption of oil filters

摘要

In the theoretical part of the paper a simple theory is presented relating filtrate clarity,filter capacity and energy consumption. The particle size distribution is subdivided in coare, intermediate and fine particles. The key role play the intermediate particles who can enter and colg the filter medium. This combined with a layered cake model selects complete blocking as the filtration mechanism for the intermediate particles. In the experimental part results are given on the Multipass flat cell filtration of SAE 5-80 test dust in oil, monitorng upstream and downstream pressure and particle concentration as a function of time. For the chosen filter media and within the experimental range of flow and concentration the simple theory can be applied successfully to these SAE oil filtration experiments.
