An oil filter with a segmented pre-filter structure

Abstract

The invention discloses an oil filter with a sectional type pre-filtering structure. The oil filter comprises a filter element, an outer barrel and an inner barrel. When the oil filter with the sectional type pre-filtering structure works, engine oil in buffer cavities enters the inner barrel through filtering films, the buffer cavities enter the working state from bottom to top in sequence, the flowing speed of the engine oil input into the inner barrel from the outer barrel is guaranteed, it is guaranteed the flowing speed of engine oil which is in the inner barrel and overflows upwards to enter the filter element, and the working efficiency of the filter element is guaranteed. According to the oil filter, through the arrangement of the multiple layers of buffer cavities and the filter films corresponding to the buffer cavities in a one-to-one manner, earlier period filtering is achieved for burden alleviation of the filter element, and the stabilization of the filtering efficiency of the filter element is guaranteed.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to an oil filter with a segmented pre-filter structure. Background technique [0002] When the filter works, the liquid to be filtered is filtered through the filter element. In the oil circulation process, the oil needs to be filtered through the filter, but the existing oil filter has the following problems: 1. The filter element is easy to be blocked, and there is a risk of engine oil supply interruption; 2. With the filter As the working time of the filter increases, the smoothness of the filter element decreases, and the oil circulation flow rate decreases, so the oil supply speed and oil supply quality cannot be guaranteed. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an oil filter with a segmented pre-filter structure. [0004] An oil filter with a segmented pre-filter structure pr...
