Abstract

A helimagnetism engine oil filter element sleeve for an automobile engine adopts the technical scheme that strip-shaped soft magnetic material is clung to an iron housing of a filter element helically to form a helical overall sleeve structure. The strip-shaped soft magnetic material can be wound around and firmly adsorbed to engine oil filters of different diameters, so as to enable iron scales in the engine oil to be deposited on the inner wall of the iron housing for preventing the iron scales from blocking an engine oil line and the filter element and prolonging the service life of the filter element; and engine oil flows out of an oil outlet after purified by multiple magnetic fields formed by helical soft magnetic material and filtered by the filter element, so that the filtering effect is improved.

Description

Helimagnetism motor car engine oil strainer core retainer plate

Technical field

The utility model relates to a kind of filter core cover of automobile engine lubricating oil filtrating equipment, the oil filter magnetic filter core cover that especially adopts the helical soft magnetic material to make.

Background technique

At present, known oil filter generally is made of shell and filter core, with filter paper as filter medium.Can remove metal granule and impurity greater than 13 microns, but then powerless for the superfine metal particle below 13 microns.There is the metal particle more than 40% can not filtering, is blended in the machine oil.

Oil discharge screw in some oil filter oil sump also is magnetic, but a little less than the magnetic, long period of soaking can be demagnetized in high temperature oil, and general motor maintains when emitting used oil full 4,000 kilometers running-in periods, has gathered a large amount of metal particles above can seeing.

Also have the artificer also to adopt the mode of external magnetic absorption to solve above problem, method is with the magnetic sheet of single circle or with the magnetic sheet of subdivision watt formula in the outside of filter core.

Fact proved, generally to have certain narrow limitation though these adsorbent equipments have adsorption effect:

1, the applying between filter core cover and the filter case relies on magnetic absorption fully, so poor reliability;

2, along with the prolongation of motor service time and the aggravation of vibration might cause coming off the Security deficiency;

3, bad adaptability, because filter case is not of uniform size, the filter core cover can not adapt to the filter core of different-diameter size well.

Summary of the invention

In order to overcome existing oil filter metal particle is filtered inadequate shortcoming, the utility model provides a kind of functional reliability higher oil strainer core retainer plate, this oil strainer core retainer plate is by the magnetization of helical soft magnetic material, can effectively adsorb trickle iron filings at the iron shell inwall of filter core, make it to be deposited on the iron shell inwall, can not only effectively improve filtering effect, also be difficult for stopping up filter screen, and safer, reliable.

The technological scheme that its technical problem that solves the utility model adopts is: the iron shell in the outside of element of oil filter iron shell with soft magnetic material and filter core fits tightly into spiral whole sleeve-like structure.Because the helical area of contact is big, then the magnetization area is big, and magnetic force comprehensively, fully can make it to be deposited on the iron shell inwall at the effective trickle iron filings of absorption of the inwall of the iron shell of filter core.During change engine oil, the abrasive dust and the old oil filter that are adsorbed are together abandoned.

Irony abrasive dust in the machine oil just thoroughly is adsorbed in the Magnetic filtration device oil circuit before no show papery filter core, has avoided the irony abrasive dust that engine oil passage and papery filter core are stopped up, thereby the life cycle that has prolonged the papery filter core makes the machine oil circulation more smooth and easy.

During assembling, soft magnetism filter core bar is spirally wrapped around on the iron shell of filter core, can fits, bigger adaptability is arranged with the filter core iron shell of different size dimensions.Simultaneously, soft magnetism filter core bar has certain elastic force, under the double action of elastic contractile force and magnetic attraction, helical soft magnetic material and filter core iron shell is fitted tightly, and has further improved high efficiency, Security and reliability that machine oil filters.

The beneficial effects of the utility model are:

1,, avoided iron filings to stop up engine oil passage and papery filter core, thereby the life cycle that has prolonged the papery filter core make the machine oil circulation more smooth and easy because iron filings are deposited on the inwall of filter core iron shell; Prolong replacing lubricating oil blanking time, can reduce the maintenance and repair expense, saved user cost;

2, good filtration effect makes engine lubrication system more most perfect, and each moving surface friction is little, and in-fighting is few, and useful horsepower is higher, and more fuel-efficient;

4, magnetized machine oil, made the machine oil can be attached on each rubbing surface when engine cold-start, the lubricity during startup be good;

5, long-term use can reduce oil consumption, can cut down expenses again, and stronger economic benefit is arranged.New car uses its effect of this product better in running-in period;

6, Gong Zuo Security, reliability, adaptability are stronger, and long service life is reusable;

7, can fit with the iron shell of different size filter core, can adapt to the iron shell of different-diameter size filter core;

8, simple in structure, easy for installation, quick.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the erection drawing of the utility model filter core cover and filter core iron shell.

Fig. 2 is the stereoscopic figure of the utility model filter core cover and filter core iron shell.

1. soft magnetic materials among Fig. 1 and Fig. 2,2. iron shell, 3. filter core.

Embodiment

In Fig. 1, bar shaped soft magnetic material (1) is starting point with the bottom, and curl is close on the filter core iron shell (2), forms spiral overall structure, entangles filter core iron shell (2).During assembling, bar shaped soft magnetic material (1) curl is tightened up to be enclosed within on the iron shell (2), the diameter that is equivalent to the spiral sleeve-like structure of bar shaped soft magnetic material (1) formation is slightly less than the diameter of filter core iron shell (2), under the double action of elastic contractile force and magnetic attraction, the helical soft magnetic material (1) and the iron shell (2) of filter core are fitted tightly, be adsorbed on the irony filter case (2) difficult drop-off firmly.Because the length of bar shaped soft magnetic material (1) is selected for use conveniently, so can fit with the filter core iron shell (2) of different size size, stronger adaptability is arranged.

When machine oil when filler opening enters engine oil passage, under the powerful the action of a magnetic field of helical soft magnetic material (1), impel iron filings in the machine oil to be deposited on the inwall of iron shell (2), avoided iron filings to stop up engine oil passage and papery filter core (3), thereby prolonged the working life of papery filter core (3), made the machine oil circulation more smooth and easy; A part can not be attracted to the inwall of iron shell (2) by the irony abrasive particle of filter core (3) filtration, after the purification of multiple magnetic field and filter core (3) filtration of machine oil through helical soft magnetic material (1) formation, from the oil outlet outflow, has improved filtering effect.
