The upper location structure that positioning string filter core is set.It can specifically be determined according to the specific connected mode between each part, also may be used
Determined according to the convenience of processing.For example, when string filter core 5 is close to side in metal filter screen 4 and set, and cover
Using being threadedly coupled between 3 and filter case 2, then cover and be not suitable for setting location structure 31 again on 3, need to only be set on base 1
Location structure 12.3 and the center of base 1 are covered when string filter core 5 is arranged on, then covers to set simultaneously on 3 and base 1 and determines
Bit architecture.
In a preferred embodiment, the end face of base 1 is connected through a screw thread with the bottom of filter case 2, the end face of base 1 with
Sealing gasket 7 is provided between the bottom of filter case 2, base end face is provided with knob 13.Due to base end face and filter case bottom it
Between be provided with sealing gasket 7, so as to form good sealing in the gear chamber cover of base and diesel engine, avoid oil filter from leaking
Oil.Meanwhile knob 13 has been additionally provided with base, so as to facilitate rotating base.
In the utility model, the filter case 2 can be that the materials such as plastics, metal are integrally formed.
Miniature oil filter filter method of the present utility model is：The mounting hole 11 of base 1 is first installed on diesel engine
Gear chamber cover 8 on, the machine oil that need to be filtered is sent into oil filter by lubricating oil pump in diesel engine, first passes through metal filter screen
Large granular impurity in 4 filtering machine oil, then part filters the little particle impurity in machine oil by string filter core 5 again, most
The machine oil filtered by oil filter flows out from the oil-out 21 of filter case 2, enters back into diesel-engine body internal oil channel.Although
String filter core every time can only filtration fraction machine oil, but because machine oil is constantly recycled into oil filter, pass through plant
The continuous circulating filtration of fabric filter element, ensure to remove the molecule in machine oil totally.
Miniature oil filter of the present utility model, due to being provided with string filter core 5 in filter case, so as to
Molecule in machine oil is further filtered, avoids the friction such as bearing shell, cylinder sleeve, piston, gear in diesel engine from transporting
The abrasion of dynamic parts, improve the power and service life of diesel engine.Meanwhile positioned by being set in base 1 and/or capping 3
The location structure of string filter core, string filter core 5 can be avoided to be shifted over, and then avoid string filter core from blocking out
Hydraulic fluid port 21.By seeing vertically arranged barrier 6 in string filter core 5 and oil-out 21, string filter core is further avoided to block up
Fill in oil-out 21.
The cleaning method of miniature oil filter of the present utility model is：When oil filter needs cleaning, first unclamp
The connection of the gear chamber cover 8 of base 1 and diesel engine, oil filter is taken out, then by base 1, capping 3 respectively with filter case
2 take apart, then take out metal filter screen 4, string filter core 5, barrier 6 respectively, clean metal filter screen 4 and barrier successively
6, and string filter core 5 is recycled.After metal filter screen 4 and barrier 6 are dried, then by 4 sets of metal filter screen
Enter the content of filter case 2, the both ends of string filter core 5 after replacing be inserted in base 1 and the location structure of capping 3 respectively,
And barrier 6 is vertically installed between string filter core 5 and oil-out 21, after installing, capping 3 is installed on filter case
2 tops, then the bottom of filter case 2 is installed on base 1.The mounting hole 11 of base 1 is finally installed on the gear of diesel engine
On chamber cap 8.
The cleaning method of miniature oil filter of the present utility model is：When oil filter needs cleaning, first unclamp
The connection of the gear chamber cover of base and diesel engine, oil filter is taken out, then base, capping are torn open with filter case respectively
Open, then take out metal filter screen, string filter core, barrier respectively, clean metal filter screen and barrier successively, and will plant
Fibres filter core is recycled.It is inserted in after metal filter screen and barrier drying, then by metal filter screen in filter case
Hold, the string filter core both ends after replacing are inserted in base and the location structure of capping respectively, and in string filter core
The vertical installation barrier between oil-out, after installing, by lidstock at the top of the filter case, then by filter case bottom
It is installed on base.Finally the mounting hole of base is installed on the gear chamber cover of diesel engine.Miniature machine oil of the present utility model
Cleaner is easy to clean, need to only clean metal filter screen and barrier, and changes string filter core, and oil filter then can be again
Use.Meanwhile miniature oil filter dismounting of the present utility model is simply, need to only unclamp the gear chamber cover of base and diesel engine
Fixing bolt, oil filter can be removed from diesel engine.Meanwhile base and capping can be connected by screw thread and filter case
Connect, take base and capping with filter case respectively apart so as to convenient.In a word, oil filter structure letter of the present utility model
It is single, dismantle and easy to clean.
Although the foregoing describing specific embodiment of the present utility model, those familiar with the art should
Work as understanding, the specific embodiment described by us is merely exemplary, rather than for the limit to the scope of the utility model
Fixed, those skilled in the art are in the equivalent modification and change made according to the technical solution of the utility model, all
It should cover in scope of the claimed protection of the present utility model.
