Background

The filter is a device that filters impurities or gas through a filter paper or a filter net. The method is divided into the following steps according to different filtering functions: oil filters, fuel filters (gasoline filters, diesel filters, oil-water separators, hydraulic filters), air filters, air-conditioning filters, and the like. In the process of recycling the engine oil and the lubricating oil, metal abrasive dust, carbon deposit and colloidal precipitate oxidized at high temperature, water and the like are continuously mixed into the oil. The filter is used for filtering out the mechanical impurities and colloid, keeping the oil clean and prolonging the service life of the oil. The filter should have strong filtering ability, small flow resistance, long service life and the like. The structure of the most formula as an organic whole of current filter, filter long-time back of using, a large amount of impurity of filter screen surface adhesion lead to the resistance of filter increasingly high. The existing treatment mode is that the filter is smoother integrally, so that the waste of resources is caused.
