Centrifugal Oil Filtration - Principle Of Operation

Oil from a pressure point on an engine is fed through the side inlet of the Centrifuge. When the oil pressure exceeds cutoff valve rating, the spring loaded plunger is pushed back and the oil enters the rotor assembly through the internal drilling of the central spindle. The rotor assembly gets pressurized and the only exit point for the oil are the two tangentially opposed nozzles at the base. The rotor assembly has two bush bearings, one at the top and one at the bottom and spins freely around the spindle. The action of oil exiting through the nozzles gives it a reverse direction spin. The rotor RPM is directly proportional to the inlet pressure. The oil is returned back under gravity through the central hole at the base of the centrifuge. At 6 BAR pressure the RPM generated for model FM060 is 6000 which generates centrifugal force 2000 times that of gravity. Each particle heavier than oil is subjected to tremendous centrifugal force and gets compacted onto the inner rotor wall. At pre-determined intervals the rotor assembly is cleaned with the help of a wooden spatula.
