Abstract
The present invention discloses one kind of engine oil filtering element, which includes one upper end cap, one lower end cap, one filtering cartridge and one central tube. The filtering cartridge is constituted with filter paper forming wavy folded sheets around the central tube; and the upper end cap and the lower end cap are set on two ends of the filtering cartridge. The engine oil filtering element of the present invention has great filtering area, great flow rate, less resistance and long service life.
Description
[technical field]
The present invention relates to a kind of filter element of filter well cuts.
[background technique]
At present, known filter element is by end cap, filter cylinder and center tube and other auxiliary component constitute up and down, its filter cylinder is to be become some foldings and constitute in center tube upper edge circumference by filter paper, and important performances such as the resistance of filter cleaner flow and working life are directly relevant with filter paper.In known technology, above-mentioned folding is a flat, if the folding of this flat is too much in order to increase filter area folding number on the circumference of center tube, then squeezes overstockedly, can increase the resistance of machine oil on the contrary.And present often some supporting producer requires under identical specification with the client, makes the big filter cleaner of filter area, to save cost.So under same size, rely on increase folding number to increase filter area and be difficult to accomplish.Simultaneously, known filter core its up and down end cap be to adopt metally, the end cap of this metal is a kind of cylinder of opening, the high nearly 5MM of the stile of its cylinder, it is installed in the two ends of filter cylinder, and its stile covers the part of filter cylinder, has also reduced filter area.
[summary of the invention]
In view of the deficiency that exists in the background technique, the technical problem to be solved in the present invention provide a kind of under same size filter area reach maximum machine oil filter core.
In order to address the above problem, the present invention realizes by the following technical solutions: a kind of machine oil filter core, comprise end cap, filter cylinder and center tube up and down, described filter cylinder is arranged to some foldings by filter paper and constitutes on the circumference of center tube, end cap is arranged on the two ends of filter cylinder up and down, it is characterized in that described each folding that is arranged in the center tube circumference all is wavy; On center tube, be connected with pull bar; Described end cap is up and down made by epoxy resin.
Among the present invention, with the folding of filter core be arranged to wavy after, under same size and identical folding number, increased filter area widely, through calculating, the wavy folding of this employing is compared with the folding of flat in the known technology, its filter area increases more than 60%, thereby its flow increases considerably, and reduced resistance, prolonged the life-span; End cap adopts epoxide resin material up and down simultaneously, has replaced the metal end in the conventional art, because epoxide resin material is got final product with the two ends that Bond is bonded in filter cylinder, thereby there is not a cylinder stile in the known technology, like this, end face just can not cover filter cylinder, has increased filter area again.
[description of drawings]
The present invention is further described in conjunction with the accompanying drawings and embodiments more below.
Fig. 1 is prior art constructions figure of the present invention;
Fig. 2 is a sectional view of the present invention;
Fig. 3 is a structural drawing of the present invention.
[embodiment]
With reference to Fig. 1, this machine oil filter core, comprise end cap 1,6, filter cylinder 2 and center tube 3 up and down, described filter cylinder 2 is arranged to some foldings 7 by filter paper and constitutes on the circumference of center tube 3, wherein each folding all is wavy, end cap 1,6 is arranged on the two ends of filter cylinder 2 up and down, the present invention adopts 1, the 6 usefulness Bonds of end cap up and down of epoxide resin material center tube 3 and filter cylinder 2 bondings, the oil-feed of filter core with fuel-displacedly separate by filter cylinder 2, the end cap made from this epoxide resin material up and down 1,6 is than increased bigger filter cylinder filter area with metal end.Center tube 3 is used for supporting filter cylinder 2, increases the intensity of filter core, and machine oil from the outer surface of filter cylinder 2 after filtering, and is fuel-displaced from center tube 3.Cylinder lever connecting rod 4 on center tube 3, when being convenient for changing filter core, with pulling moving pull bar 4, just filter core can be proposed, and at the other end of pull bar 4 seal ring 5 are installed, the joint of sealing filter core and assembly.
Claims (3)
1, a kind of machine oil filter core, comprise end cap (1 up and down, 6), filter cylinder (2) and center tube (3), described filter cylinder (2) is arranged to some foldings (7) by filter paper and constitutes on the circumference of center tube (3), end cap (1 up and down, 6) be arranged on the two ends of filter cylinder (2), it is characterized in that described each folding (7) that is arranged in center tube (3) circumference all is wavy.
2, machine oil filter core according to claim 1 is characterized in that being connected with on the described center tube (3) pull bar (4).
3, machine oil filter core according to claim 1 and 2 is characterized in that described up and down end cap (1,6) made by epoxy resin.
