CENTRIFUGAL SEPARATOR FOR LIQUID FILTRATION

The present invention provides a centrifugal separator for liquid filtration to filter foreign substance included in the oil through rotating the oil circulating inside an engine of a vessel with pressure and high speed. The centrifugal separator for liquid filtration (10) is formed in order that a spraying hole (42) formed in a sleeve (40) can have inclined angle from lower side of a rotor cover (50) into the inside of the rotor cover (50). The oil flowing into a rotor cavity (31) through the sleeve (40) by having a simple composition forms a stable flow toward the inside (52) of the rotor cover (50). Furthermore, the rib has a length which is shorter than a vortex type rib gathered in the center point like Mann and Hummel; and longer than the rib perpendicularly formed as like existing technology by making a guiding rib (54) formed in the rotor cover (50) to comprise a tangent in a center hole (51) which is combined with the sleeve (40). Therefore, the foreign substance mixed with the oil can be effectively filtered while maintaining an active ingredient. [Reference numerals] (AA) Inflow; (BB) Outlet
