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:
The present invention relates to hydraulic system, be specifically related to a kind of oil-feed oil filter.
Background technology:
Oil-feed oil filter, its filter core be take copper mesh as filtering material, has around on the plastics or metal cylindrical skeleton in a lot of holes, is wrapping one deck or two-layer copper mesh, and its filtering accuracy depends on the size of the copper mesh number of plies and mesh.This oil filter structure is simple, and through-current capability is large, easy to clean, but filtering accuracy is low, is generally used for the inlet port of hydraulic pump.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defect of prior art, and the oil-feed oil filter that a kind of filtering accuracy is high is provided.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of oil-feed oil filter, comprise housing, in housing, be provided with filter core, housing top is provided with end cap, and end cap is provided with fuel feed hole, and housing below is provided with Self-sealing valve, it is characterized in that: described oil-in is bellmouth orifice, bellmouth orifice macropore is in housing, and described fuel feed hole medial surface is provided with groove, is provided with the annular magnet that two halves annulus magnet forms in groove.
In described annular magnet, be trapped in groove the outstanding groove in surface.
The present invention is simple in structure, reasonable in design, at oil-in, is provided with magnet adsorption iron filings impurity, simultaneously for avoid absorption after iron filings again along with hydraulic oil washes away, again infiltrate in oil, fuel feed hole is made as bellmouth orifice, is attached on magnet after iron adsorption, good filtration effect, improves oily progress, successful.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Wherein: 1: housing; 2: filter core; 3: end cap; 4: fuel feed hole; 5: Self-sealing valve; 6: groove; 7: annular magnet.
The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
A kind of oil-feed oil filter as shown in Figure 1, comprise housing 1, be provided with filter core 2 in housing 1, housing 1 top is provided with end cap 3, end cap 3 is provided with fuel feed hole 4, housing 1 below is provided with Self-sealing valve 5, and wherein oil-in 4 is bellmouth orifice, and bellmouth orifice macropore is in housing 1, wherein fuel feed hole 4 medial surfaces are provided with groove 6, in groove 6, be provided with the annular magnet 7 that two halves annulus magnet forms, in annular magnet 7, be trapped in groove 6, the outstanding groove 6 in surface.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
