Description

Magnetic filter element oil filter

Technical field

The present invention relates to auto-parts technical field, is specially a kind of magnetic filter element oil filter.

Background technology

Oil filter is referred to as machine filter, and can engine work normally, and is being sent out depending on the lubrication of machine oil, but in machine oil Long-term work in motivation, easily produces impurity, the device of this oil filtration in need, and oil filter is exactly to be used for completing The device of oil filtration, the effect of machine filter be in the machine oil of oil sump objectionable impurities filter out, with clean machine oil The kinematic pairs such as bent axle, connecting rod, camshaft, booster, piston ring are supplied, lubrication, cooling, cleaning action are played, so as to extend this The service life of a little parts.Machine filter is located in engine lubrication system, and the upstream of machine filter is lubricating oil pump, and downstream is needed in engine Each parts of lubrication.During internal combustion engine use, the mechanical admixtures such as dust, galling, carbon are clear will be constantly mixed into machine oil, Air and the exhaust gas of burning can also make machine oil gradually produce colloid the oxidation of machine oil at the same time.Mechanical admixture is mixed with colloid Greasy filth can be also formed afterwards, this can not only accelerate the abrasion of part, but also easily cause the blocking of oil circuit.To ensure the clear of oil circuit Clean, engine is equipped with oil filter in lubricating system.

Oil filter needs replacing element of oil filter after the certain milimeter number of running car, the filter used at present Core is using the filter paper folded, and the service life of filter paper is shorter, and filter paper uniform pore diameter, to the mistake of impurity particle of different sizes Filter property is poor, it is easy to results in blockage.

A kind of to solve the above problems, currently proposed magnetic filter element oil filter.

The content of the invention

It is proposed in the above background technology to solve it is an object of the invention to provide a kind of magnetic filter element oil filter Problem.

To achieve the above object, the present invention provides following technical solution：A kind of magnetic filter element oil filter, including master Body, the main body are equipped with metal shell, strainer cover, filter core and thread plate, and the strainer cover is equipped with exterior seal ring, Be equipped with thread plate between the strainer cover and the metal shell, the thread plate is equipped with edible vegetable oil outlet and dirt have into Mouthful, the sump oil import is arranged on the periphery of the edible vegetable oil outlet, and the filter core is located at the inside of the metal shell, the filter It is sump oil chamber between core and the metal shell, the filter core includes the first strainer and the second strainer, and the both ends of the filter core are set Have a cover board and adhesive, the filter core is internally provided with central tube, the central tube with top edible vegetable oil outlet, in described The upper top of heart pipe is equipped with check-valves, and the bottom of the central tube is equipped with by-passing valve, and the by-passing valve is fixed on metal shell Bottom.

Preferably, the central tube uses electrolytic tinning steel band, and the tube wall of central tube is equipped with circular hole.

Preferably, the filter core is equipped with strength magnet ring between check-valves.

Preferably, first strainer and the second strainer are steel wire, and the aperture of the first strainer is relatively larger than the second filter The aperture of net.

Preferably, the thread plate and metal shell use cold-rolled steel sheet, and the exterior seal ring uses nitrile rubber material Matter.

Compared with prior art, the beneficial effects of the invention are as follows：The invention in the filter core of oil filter by setting Steel wire, and the aperture of the first strainer is relatively larger than the aperture of the second strainer so that filter core imitates different size of contaminant filter Fruit is improved, and prevents filter core from blocking, and improves service life, by setting the first strainer of strength magnet ring and the on filter core Two strainers have magnetism, so as to add the filter effect to iron filings impurity, prevent iron filings impurity from entering engine, cause and start Machine serious wear, filter core can be reused by cleaning, reduce production cost.

Brief description of the drawings

Fig. 1 is schematic structural view of the invention；

Fig. 2 is the filter core schematic diagram of the present invention.

In figure：1 exterior seal ring, 2 check-valves, 3 central tubes, 4 filter cores, 41 first strainers, 42 second strainers, 5 main bodys, 6 gold medals Belong to shell, 7 strength magnet rings, 8 sump oil chambers, 9 circular holes, 10 thread plates, 11 sump oil imports, the outlet of 12 edible vegetable oil, 13 strainer covers, 14 By-passing valve.

Embodiment

Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work Embodiment, belongs to the scope of protection of the invention.

- 2 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of magnetic filter element oil filter, including main body 5, The main body 5 is equipped with metal shell 6, strainer cover 13, filter core 4 and thread plate 10, and the strainer cover 13 is equipped with outer Sealing ring 1, is equipped with thread plate 10 between the strainer cover 13 and the metal shell 6, the thread plate 10 is equipped with Edible vegetable oil outlet 12 and sump oil import 11, the sump oil import 11 are arranged on the periphery of the edible vegetable oil outlet 12, and the filter core 4 is located at The inside of the metal shell 6, is sump oil chamber 8 between the filter core 4 and the metal shell 6, and the filter core 4 includes the first filter 41 and second strainer 42 of net, the both ends of the filter core 4 are equipped with cover board and adhesive, and the filter core 4 is internally provided with central tube 3, The central tube 3 is connected with top edible vegetable oil outlet 12, and the upper top of the central tube 3 is equipped with check-valves 2, the central tube 3 Bottom be equipped with by-passing valve 14, the by-passing valve 14 is fixed on the bottom of metal shell 6.

The central tube 3 uses electrolytic tinning steel band, and the tube wall of central tube 3 is equipped with circular hole 9, the filter core 4 with It is equipped with strength magnet ring 7 between check-valves 2,41 and second strainer 42 of the first strainer is steel wire, and the hole of the first strainer 41 Relatively larger than the aperture of the second strainer 42, the thread plate 10 and metal shell 6 use cold-rolled steel sheet, the exterior seal ring in footpath 1 uses nitrile rubber material.

Operation principle：Since the small iron filings of metallic particles can be produced during the use of machine, if iron filings are not by mistake Filter, it will give engine belt wheel serious abrasion, when the sump oil with iron filings from the sump oil import 11 of 10 surrounding of thread plate into Enter in oil rectifier, the first strainer 41 can be filtered the larger impurity of particle since aperture is larger, and less particle is then Filtered in the second strainer 42, since steel wire has the ability of magnetic conduction, the first strainer 41 and the second strainer 42 are in strength Also there is magnetism under the action of magnet ring 7, so as to improve the filtering to iron filings, in the central tube 3 that machine oil is entered by filter core 4, Enter engine finally by the edible vegetable oil outlet 12 at 10 center of thread plate.

Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of changes, modification, replace And modification, the scope of the present invention is defined by the appended.
