Hydraulic oil filter element is used in hydraulic system to filter out solid particles and colloidal substances in working medium. It can effectively control the pollution degree of working medium and protect the normal work of mechanical equipment. It is an indispensable part of the pipeline series of conveying medium. But hydraulic oil filter element consumption is too fast, what is the reason?
Of course, the quality of oil also determines the length of use time of the filter element. The process of pollutant loading is the process of blocking the filter element through hole. When the filter element of hydraulic oil is blocked by pollution particles, the number of holes that can pass through the liquid flow will be reduced. In order to ensure the flow rate through the filter material, the pressure difference will increase.
2. In the initial stage, because there are many holes in the hydraulic oil filter element, the pressure difference through the filter element grows slowly, and the blocked holes have little impact on the overall pressure loss. However, when the plug hole reaches a value, the plug is very rapid, at which point the differential pressure through the hydraulic oil filter element rises very quickly.
3. The number, size, shape and distribution of holes in a hydraulic oil filter element indicate why one filter element has a longer life than the other.
4. For a filter material of a given thickness and filtration accuracy, the filter paper has fewer holes than the glass fiber filter, and therefore the filter element of the filter paper material will clog faster than the glass fiber filter element. The filter core of the multilayer glass fiber filter can accommodate more pollutants. When the liquid flows through the filter core, each filter layer filters out particles of different sizes. The small holes in the filter material of the back layer are not blocked by large particles, and the small holes in the filter material of the back layer still filter a large number of small particles in the fluid.
