Description
Technical field
The utility model relates to a kind of oil filter.
Background technique
Oil filter on the market, very large shortcoming: can only in filtering machine oil 60% impurity, filtering efficiency is low; Under specific condition, filtering efficiency is zero; Oil filter best on market, also can only be designed into the ability of 60% impurity in filtering machine oil, this maximum filtering value drawn after being through thousands of times experiment.In actual use, also have the objectionable impurities of 40%, can not by the effective filtering of paper filter element, in this 40% impurity, because Ferromagnetic Impurities is relatively tiny and hard, so in the majority with Ferromagnetic Impurities, it is also just maximum to engine damage.
The oil filter of existing use, all bypass valve is provided with in the bottom of paper filter element, this is when designing, in order to consider motor at cold start-up engine oil viscosity large or paper filter element by Partial Blocking or all block time, ensure that machine oil energy smooth circulation postbacks motivation and the direct oil flow channel that designs.When opening bypass valve under the pressure of machine oil at oil pump, the machine oil now looping back motor through bypass valve not only can not get the filtration of paper filter element, but also can by original by large granular impurity that paper filter element filters out, through bypass valve again refunds in motor, continual secondary is brought to wear and tear to motor, therefore the oil filter used on the market, does not have filtration under specific condition at all, so filtering efficiency is now zero.
Summary of the invention
In order to overcome the defect of prior art, the utility model provides following technological scheme:
A kind of oil filter, it comprises lid, metallic case and filter core, lid and metallic case upper end are sealedly and fixedly connected, described lid is provided with filler opening, oil outlet, described oil outlet is communicated with the first oil discharge passage in lid and the second oil discharge passage, described filter core is located in metallic case, filter core comprises axis, the middle part of axis is provided with filter screen and filter paper from inside to outside, described first oil discharge passage matches with filter screen, be provided with magnet bottom described metallic case, described axis upper end is connected with the nut above lid, and lower end is connected with bottom metallic case by spring.
Further, described oil outlet is provided with safety check, and described second oil discharge passage upper end is provided with bypass valve.
The beneficial effect that the utility model brings is: can effectively be removed by the Ferromagnetic Impurities in machine oil, filtering efficiency is high, extends service life of aeroengine.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Number in the figure is:
1, lid; 2, metallic case; 3, filter screen; 4, axis; 5, filter paper; 6, bypass valve; 7, safety check; 8, magnet; 9, spring; 10, nut; 11, oil outlet; 12, filler opening.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in the figure, a kind of oil filter, it comprises lid 1, metallic case 2 and filter core, lid and metallic case 2 upper end are sealedly and fixedly connected, described lid 1 is provided with filler opening 12, oil outlet 11, described oil outlet 11 is communicated with the first oil discharge passage 13 in lid and the second oil discharge passage 14, described filter core is located in metallic case 2, filter core comprises axis 4, the middle part of axis 4 is provided with filter screen 3 and filter paper 5 from inside to outside, described first oil discharge passage 13 matches with filter screen, magnet 8 is provided with bottom described metallic case, described axis upper end is connected with the nut 10 above lid, lower end is connected with bottom metallic case by spring 9.Described oil outlet is provided with safety check 7, and described second oil discharge passage 14 upper end is provided with bypass valve 6.
The advantage that embodiment described in the utility model has is: can effectively be removed by the Ferromagnetic Impurities in machine oil, filtering efficiency is high, extends service life of aeroengine.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change can expected without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
