Problems solved by technology

Therefore, under the same specifications, it is difficult to increase the filter area by increasing the number of folding pages.
Simultaneously, its upper and lower end caps of the known filter element are made of metal, and the end caps of this metal are a kind of open cylinder, and the standing edge height of its cylinder has about 5MM, and it is installed on the two ends of filter cartridge , its vertical side covers a part of the filter cartridge, which also reduces the filter area

Embodiment Construction

[0010] Referring to Fig. 1, the oil filter element includes upper and lower end covers 1, 6, a filter cartridge 2 and a center pipe 3. The filter cartridge 2 is formed by arranging filter paper into several folds 7 on the circumference of the center pipe 3, each of which The hinges are all wavy, and the upper and lower end caps 1, 6 are arranged at both ends of the filter cartridge 2. The present invention adopts the upper and lower end caps 1, 6 of epoxy resin material to bond the central tube 3 and the filter cartridge 2 with an adhesive Get up, the oil inlet and the oil outlet of filter core are separated by filter cartridge 2, and the upper and lower end caps 1,6 made of this epoxy resin material have increased larger filter cartridge filtration area than metal end caps. The center pipe 3 is used to support the filter cartridge 2 and increase the strength of the filter element. After the oil is filtered from the outer surface of the filter cartridge 2, the oil is discharged...

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】 [0001] The invention relates to a filter element for filtering impurities in engine oil. 【Background technique】 [0002] At present, the known filter element is composed of upper and lower end caps, a filter cartridge, a central pipe, and other auxiliary parts. Important properties such as resistance and service life are directly related to filter paper. In the known technology, the above-mentioned hinges are flat. If there are too many folds on the circumference of the central tube in order to increase the filtration area of ​​this flat hinge, it will be crowded too densely, which will increase the oil pressure on the contrary. resistance. However, at present, some supporting manufacturers and customers often require to make filters with a large filtration area under the same specifications in order to save costs. Therefore, under the same specifications, it is difficult to increase the filter area by increasing the number of folding pages. Simultaneou...
