Abstract

The utility model discloses a high precision magnetic filter which comprises a casing, a supporting spring, an upper end cover, a lower end cover, a safety valve, a check valve, a screw cover plate and a filter element. The filter element arranged between the upper end cover and the lower end cover comprises a center tube and filter paper. The bottom part of the filter paper is provided with the safety valve which comprises a valve clack, a valve spring and a valve seat. The bottom part of the lower end cover is connected with the casing through the supporting spring. The screw cover plate is arranged above the upper end cover. The check valve is arranged between the screw cover plate and the upper end cover. The utility model is characterized in that the upper surface of the upper end cover and the lower surface of the lower end cover are absorbed with strong magnetic sheets. The utility model has the beneficial effects that the filtration efficiency of the filter is improved and the service life of an engine is prolonged.

Description

A kind of high accuracy magnetic filter
Technical field
The utility model relates to a kind of machine oil filtering and cleaning device, relates in particular to a kind of high accuracy magnetic filter.
Background technology
Present known oil filter, not ideal always in effect aspect the filtration of the metal impurities in the machine oil, can only pore size filter be the impurity of 40~80um.After the machine oil that contains the small-bore metal impurities enters cleaner,, can continue impurity is brought into the miscellaneous part of engine, cause damage because impurity can not get effective filtration; Too much metal impurities can be collected on the filter core, have influenced the filter effect of filter core.The maximum pressure that safety valve can bear is 1 kilogram, if the time is long when not changing filter paper or automobile starting, all can makes the safety valve pressurized overstep the extreme limit and opens, and causes the impurity of filter core absorption to spray with machine oil.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, proposes a kind of high accuracy magnetic filter of effectively filtering metal impurity.
The technical solution of the utility model is as follows: a kind of high accuracy magnetic filter comprises shell, support spring, upper end cover, bottom end cover, safety valve, check-valves, thread plate and filter core; Filter core is located between upper end cover and the bottom end cover, comprises central tube and filter paper; The filter paper bottom is provided with safety valve, and safety valve comprises valve bowl, valve spring and valve seat; The bottom end cover bottom is connected with shell by support spring, and the upper end cover top is provided with thread plate, is provided with check-valves between thread plate and the upper end cover, is adsorbed with strong magnetic piece at upper end cover upper surface and bottom end cover lower surface.
As to improvement of the technical scheme, described strong magnetic piece is a ring-type, and thickness is greater than 1.5mm.
As to improvement of the technical scheme, the outer casing inner wall stage casing is adsorbed with magnetic, and described magnetic is a cylinder, is symmetricly set on the outer casing inner wall; Also can be symmetricly set on the outer casing inner wall for a watt shape.
The beneficial effects of the utility model are: after adding strong magnetic piece on upper end cover and the bottom end cover, and can be in the inner magnetic current loop that forms of cleaner; When the machine oil of containing metal impurity entered cleaner, metal impurities can be adsorbed by strong magnetic piece, no longer flows into oil piping system, and the utility model can filter the metal impurities that the minimum-value aperture is 2um; Also can reduce attached to the metal impurities in the filter core, strengthen the filter effect of cleaner; The infringement that each parts of engine are subjected to reduces, and has prolonged engine life.
Below in conjunction with accompanying drawing the utility model is described further.

The specific embodiment
With reference to Fig. 1, high accuracy magnetic filter, its filter core comprise central tube 9 and filter paper 10, and filter paper 10 is by hot-setting adhesive 4 and upper end cover 11 and bottom end cover 5 bondings; Central tube 9 bottoms are provided with safety valve, and safety valve comprises valve bowl 6, valve spring 7 and valve seat 8; All be attached with annular strong magnetic piece 3 on upper end cover 11 and the bottom end cover 5; Bottom end cover 5 belows link to each other with shell 1 by support spring 2, and shell 1 inwall stage casing is provided with magnetic 16; Upper end cover 11 tops are provided with thread plate 13, are provided with check-valves 12 between thread plate 13 and the upper end cover 11; Thread plate 13 and exterior seal ring 15 apical graftings, exterior seal ring 15 is connected with the shell top by sealing ring fixed plate 14; Thread plate 13 is provided with oiler 17, and is identical with check-valves 12; The thread plate center is provided with oil-out 18, and oil-out 18 communicates with central tube 9.
When lubricated, machine oil enters from oiler, and a part of metal impurities are adsorbed by the strong magnetic piece of upper end cover; After machine oil enters cleaner, infiltrate through in the central tube, then flow out from oil-out by filter paper; During by filter paper, the magnetic of filter paper and outer casing inner wall produces dual filter effect to the impurity in the machine oil; When safety valve was backed down, machine oil directly entered central tube from safety valve, and at this moment, the strong magnetic piece of bottom end cover can adsorb the most of metal impurities in the machine oil.
