Oil filter element that effectively uses balanced magnetic field lines that repel permanent magnets

摘要

[Objective] Reduction of exhaust pollutant gases (CO, HC, NOX) and particulate emissions (PM2.5) due to the effect of preventing deterioration of oil in the magnetic field lines of a well-balanced permanent magnet, and fine iron powder by ISO281 Provided is an oil filter element that replaces the filter paper element of a filter paper type oil filter for the purpose of extending the life of a bearing by adsorption. [Configuration] Instead of filter paper for the oil filter element, the hollow disk shape is represented by {(outer diameter-inner diameter) / 2 / height}. A pair of odd-numbered permanent magnets 3 having yokes 2 on both end faces having three magnetic poles, and adjacent permanent magnets 3 are paired with a gap composed of N and N poles and a gap composed of S and S poles. Or a plurality of pairs of gaps are set in the nipple magnet holder 5 so that the permanent magnets 3 are arranged on the same center line with the yoke 2 at both ends and placed on the non-magnetic material. A non-magnetic holding plate 4 having a hole through which oil can pass is provided in the gap portion of the permanent magnet 3 so that the weight of the permanent magnet 3 can be supported when the same pole is floated in the vertical direction. Install one of the odd number of permanent magnets 3 Clearance to stabilize the of the opposite ends of the nipple magnet holder 5, by placing the cap magnet holder 1, consisting to stabilize an odd number of permanent magnets 3, an oil filter element by the permanent magnet that does not use filter paper.
