Abstract
The invention discloses a vertical replaceable graded filter oil filter, comprising a filter body, the top of the filter body is threadedly connected with a sealing cover, and the inner cavity of the sealing cover is fixedly connected with a second filter The inner cavity of the sealing cover is located at the bottom of the second filter screen and filter paper is arranged, the bottom of the sealing cover is fixedly connected with a protective cover by bolts, and the surface of the protective cover is fixedly connected with the first filter screen. The present invention uses a filter body, a sealing cover, a protective cover, a sleeve rod, a limit plate, an annular spacer, a first filter element, a damping rod, a second filter element, a first filter screen, an oil inlet passage, a filter paper, and an oil outlet passage. , the second filter screen, limit spring, moving plate and vertical rod, which solves the problem that the oil filter on the existing market does not have a detachable and graded filter structure. During use, once the filter element is replaced, the overall The cost of dismantling and discarding is high, which is not conducive to the sustainable development of resources.
Description
technical field [0001] The invention relates to the technical field of engine oil filters, in particular to a vertical replaceable graded filter engine oil filter. Background technique [0002] The oil filter, also known as the oil grid, is used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine. The oil filter can be divided into full-flow type and split-flow type. The type filter is connected in series between the oil pump and the main oil passage, so it can filter all the lubricating oil entering the main oil passage, and the shunt type filter is connected in parallel with the main oil passage, and only filters part of the lubricating oil sent out by the oil pump. [0003] During the use of motor vehicles, it is necessary to use the oil filter to filter the oil. The existing oil filter on the market does not have a detachable and graded filter structure. During use, once the filter element is replaced ,...
