Abstract

The invention discloses an inlet oil filter and relates to a hydraulic system. The inlet oil filter comprises a housing, wherein a filter core is arranged in the housing; an end cover is arranged above the housing; an oil inlet is formed in the end cover; a self-seal valve is arranged below the housing. The inlet oil filter is characterized in that the oil inlet is a horn-shaped hole; a large hole of the horn-shaped hole faces to the interior of the housing; a groove is formed in the inner side surface of the oil inlet; an annular magnet comprising two semi-ring magnets are arranged in the groove. The inlet oil filter is simple in structure and reasonable in design; the magnets are arranged at the oil inlet for adsorbing scrap iron impurities; the oil inlet is designed to be the horn-shaped hole for preventing adsorbed scrap iron from being washed away along with high-pressure oil and mixed with the oil; the scrap iron is adsorbed on the magnets, so that the filtering effect is good, the oil feeding degree is increased and the effect is remarkable.

Description

Technical field: [0001] The invention relates to a hydraulic system, in particular to an oil inlet filter. Background technique: [0002] In the oil inlet filter, the filter element uses copper mesh as the filter material, and is wrapped with one or two layers of copper mesh on the plastic or metal cylindrical frame with many holes around it. The filtering accuracy depends on the number of layers of copper mesh. and mesh size. This kind of oil filter has the advantages of simple structure, large flow capacity and convenient cleaning, but low filtration precision, and is generally used for the oil suction port of the hydraulic pump. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an oil inlet filter with high filtering precision. [0004] The technical problem to be solved by the present invention is realized by the following technical solutions. [0005] An oil inlet filter, ...
