Description
Technical field
The utility model relates to a kind of oil filter, and in particular to a kind of two-layer magnetic filtering oil filter.
Background technique
In order to reduce the frictional resistance of relative motion between part in engine, reduce the abrasion of part, machine oil is sent to
The friction surface of each part forms oil film, is lubricated.Itself contains a certain amount of hazardous particulate matter, moisture and addition in machine oil
Agent.When the engine is working, metal filings can be generated, have that sundries enters, machine oil oxide can generate in air, it will make machine
Sundries in oil increases.If machine oil is directly entered lubricating system without filtering, it will the sundries in machine oil is brought into and is started
The friction surface of each part of machine increases the abrasion of part, reduces service life of aeroengine.The effect of oil filter was to filter out
Sundries in machine oil conveys clean machine oil to each engine part.
Traditional oil filter is usually only filtered by single filter paper, is had some tiny miscellaneous less than filter paper micropore
Matter can not filter, and wherein impurity Ferromagnetic Impurities are in the majority, so filter efficiency is not high.When filter paper blocking is serious, exocoel in machine filter
Pressure difference increases, and by-passing valve is opened, and filter filter effect disappears.Machine oil will not pass through filtering, be directly entered lubricating system.It will be
The even original friction surface for being filtered out the large granular impurity come and being brought into each part of engine of sundries in machine oil, increases
The abrasion of part reduces service life of aeroengine, and smoothing effect is almost nil at this time.
Utility model content
For the deficiency in above-mentioned background technique, the utility model provides that a kind of structure is simple, can adsorb Ferromagnetic Impurities
And the two-layer magnetic that a part of impurity can be filtered after by-passing valve opening filters oil filter.
To achieve the above object, the utility model provides following technical solution: a kind of two-layer magnetic filtering oil filtration
Device, including the filter core in filter case, top cover and shell, top cover is located at the top of filter case, top cover be equipped with sump oil into
Mouth, edible vegetable oil outlet and sealing ring, top cover have sealing check-valves, which is equipped with two layers of filter paper, outer layer coarse filter paper and internal layer
Fine filtering paper has gap among two layers of filter paper, and gap bottom is provided with little spring switch, and the setting of filter core center is communicated with oil outlet
Pipeline center's pipe, central tube are internally provided with by-passing valve and connect with filter core bottom, and outer layer coarse filter paper is fixed by ferromagnetism net, internal layer
Fine filtering paper is fixed by central tube and ferromagnetism iron net, and by upper end cover and top cover apical grafting, filter core lower end passes through lower end for filter core upper end
Apical grafting spring connects with filter case support.
By using above-mentioned technical proposal, two layers of filter paper, outer coarse filter paper and interior fine filtering paper are set.Machine oil first passes through outer coarse filtration
Paper has filtering process three times finally by interior fine filtering paper using ferromagnetism iron net.Outer coarse filter paper is the big filter of filtering micropore
Paper is supported, the big impurity of main filtration by ferromagnetism iron net is fixed, is guaranteed that rear outer layer filter paper practical for a long time is not easy to plug, is filtered
Resistance variation is not too large, maintains the unimpeded of machine oil.Filtering micropore small filter paper when interior fine filtering paper, by central tube and ferromagnetism
The fixed support of iron net, the small impurity of main filtration.Ferromagnetism iron net leans on magnetic absorption Ferromagnetic Impurities, when by-passing valve is opened, iron
Magnetic impurity is not easy to be brought into engine by machine oil, enhances filter effect.
By using above-mentioned technical proposal, the filter core bottom is arranged multiple little springs and switchs, on the little spring switch
Identical in by-passing valve principle between logical two layers of filter paper, setting opens pressure and is less than by-passing valve, described when pressure reaches certain value
Snap switch open, machine oil from there through, then by ferromagnetism iron net absorption and interior fine filtering paper absorption, reach filtering effect
Fruit, when by-passing valve is opened, the little spring switch is opened, and a part of machine oil passes through, and plays filtration fraction machine oil effect.
By using above-mentioned technical proposal, it is provided with sealing ring on top cover, guarantees that the oil filter is oil-proof.
By using above-mentioned technical proposal, setting seals check-valves under top cover, is close to oil inlet, when engine misses,
The sealing check-valves can prevent oil filter side dry, and when engine is lighted a fire again, the sealing check-valves can produce immediately
Raw pressure, is sent to engine lubrication for machine oil.
By using above-mentioned technical proposal, it is provided with oil passageway between the filter core two layers of filter paper, guarantees that machine oil passes through
Smoothness is able to maintain after snap switch.
By using above-mentioned technical proposal, central tube is set among the filter core, internal fine filtering paper plays support protective effect,
It is the channel after oil filtration, connects oil outlet.
By using above-mentioned technical proposal, bottom is provided with by-passing valve in the central tube, when outer layer coarse filter paper blocking or
When engine cold-start, exocoel pressure difference increases in machine filter, and by-passing valve and snap switch are opened, and enough machine oil is sent to hair in time
Motivation lubrication.
By using above-mentioned technical proposal, the filter core bottom is provided with support spring, and the support spring pushes down filter core,
Damping, buffering can be played in running car, and filter core is prevented to be displaced.
