Description

The rotation fitting type magnetic machine oil filter

The utility model relates to a kind of device that improves the oiling agent condition in lubrication system, and specifically a kind of use has the filtrating equipment of the filter method of magnetic.

Begin from the seventies, automobile industry has generally adopted rotary mounting engine oil filter, and engine lubricating oil is filtered, and to improve the purity of lubricant oil, guarantees the proper functioning of motor.The structure of rotary mounting engine oil filter is, is contained in element kit in shell, and the lower support of element kit has interior rubber cushion and thread plate, and end cap is connected on the shell end opening.Filter cleaner is contained on the motor connecting base, and when engine running, the machine oil with certain pressure enters filter cleaner by the oil inlet hole on the thread plate, after being filtered by element kit, enters the engine lubrication part by outlet.Also be provided with bypass valve in the element kit of this filter cleaner, when engine cold-start, because engine oil viscosity is bigger, can not pass through filter core smoothly, bypass valve is opened, and machine oil enters lubrication system by bypass valve, guarantees that the cold conditions of motor short time is lubricated.After the motor operation heated up, machine oil was thinning, and bypass valve cuts out, the filter cleaner proper functioning.Lubricated when this rotary mounting engine oil filter can guarantee that engine cold state starts played certain promoting effect working life to prolonging motor.But owing to motor reasons such as wearing and tearing in the running, can constantly produce some ferromagnetism impurity, and these impurity often granularity is very little, filter cleaner can not filter out.The higher impurity of these hardness can quicken component wear after entering motor, thereby the filter cleaner effect is reduced.Thereby it is filtered out be very important.

The CN93206171 patent is a kind of oil filter with magnetic, and its structure includes body, filter core and wire netting, and there is a magnetic filtering element (cartridge) rod at the wire netting center.This filter cleaner is that the ferromagnetism impurity in the machine oil after filtering is adsorbed by magnetic filtering element (cartridge) rod the time, makes ferromagnetism impurity can not enter lubrication system.This filter cleaner has occupied the filter core inner space, thereby bypass valve can only have been removed because the volume of magnetic filtering element (cartridge) rod is bigger, but this cold start that just can not guarantee motor is lubricated, has the engine cold state of causing to start the possibility of wearing and tearing.

The purpose of this utility model just provides a kind ofly can remove ferromagnetism impurity, can guarantee the rotation fitting type magnetic machine oil filter that engine cold state has enough machine oil to be lubricated when starting again, with the usability of further raising filter cleaner.

The utility model is achieved in that filter cleaner is conventional rotary mounting engine oil filter substantially, element kit promptly is housed in shell, the lower support of element kit has interior rubber cushion and thread plate, end cap is connected on the shell end opening, filter core lower cover edge at element kit has groove, the part of magnetic post is absorbed in this groove, in magnetic post bottom retainer ring is arranged, and the retainer ring edge holds out against in the enclosure on the wall.Design philosophy of the present utility model is exactly not take the filter core inner space, and magnetic patch is arranged on the inlet passage of lower edge machine oil of filter core outside, thereby being about to the ferromagnetism impurity absorption before machine oil is filtered earlier gets rid of, and then by other impurity of filter element filtering.So just solved the incompatible situation of bypass valve and magnetic filter core rod effectively, the function of filter cleaner is brought into play best.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the novel structural representation of this reality.

As shown in the figure, in the shell 5 of this filter cleaner element kit is housed, element kit is by accompanying tubular filter paper 6 between filter core loam cake 2 and the filter core lower cover 7, and the filter paper internal layer has center tube 3.There is spring 1 on the top between filter core loam cake 2 and the shell, and the bottom surface of filter core loam cake is welded with bypass valve 4.Edge at filter core lower cover 7 has groove, and the part of magnetic post 8 is stuck in this groove, and another part is positioned on the oil passageway in the filter core outside.In magnetic post bottom retainer ring 9 is arranged, the retainer ring edge holds out against in the enclosure on the wall.Rubber cushion 12 and thread plate 13 in filter core lower cover bottom surface reinstalls, end cap 10 links together with the mode of shell 5 usefulness snap fasteners then, refills outer washer 11, promptly is assembled into a complete rotation fitting type magnetic machine oil filter.

Magnetic post 8 in this filter cleaner can have 6-16, is evenly distributed on the edge of filter core lower cover 7.The number that the magnetic post is set is with the diameter of filter cleaner and to keep having between the space enough magnetic intensities be design considerations.The retainer ring 9 of magnetic post for guaranteeing reliable supporting, can be made ring in for there to be side to play the circle ring disk on limit on retainer ring 9, interior ring links to each other with retainer ring is local, and the inner ring sleeve frame on interior rubber cushion 12, so just can further be played the effect of stable support.

No matter this filter cleaner is the engine cold state starting or runs well, and the ferromagnetism impurity in the machine oil can both filtered out through before the filter core in advance, thereby can alleviate the burden of filter core, prolongs the working life of filter core.Can improve 10% through the original filter efficiency of advance copy machine, myriametre sport car test card is bright, and auto idle speed is stable, and acceleration performance improves, and fuel consumption reduces 2-4%, and the machine oil variable color is less, and is satisfactory for result.The utlity model has the filter efficiency height, resistance is little, filter precision is high, the life-span is long, prolong machine oil service time, reduce engine scuffing, prolong characteristics such as motor working life and the general character are strong.
