working principle
Huahang

The working principle of hydraulic filter element is to separate impurities and pollutants in the liquid through physical filtration and chemical adsorption, in order to ensure the normal operation of the hydraulic system.

Hydraulic filter cartridge usually consists of two parts: filter material and filter cartridge housing. Filter material is made of materials such as fibers, metal wire mesh, or porous ceramics, which can filter out larger particles and solid impurities. And the filter housing plays a supporting and sealing role.

When the liquid passes through the hydraulic filter element, due to the structural characteristics of the filter material, most of the particles and impurities will be intercepted by the filter mesh or pores, thereby reducing the solid impurities in the liquid. At the same time, some small particles and pollutants dissolved in the liquid will undergo chemical adsorption with the surface of the filter material, further purifying the liquid.

The filter element will gradually become dirty after a period of use, and it is necessary to clean or replace the filter element to maintain its filtering effect. Irregular maintenance and replacement of hydraulic filters are important measures to ensure the long-term stable operation of hydraulic systems.

Dissolve potassium dichromate or crystals in water to 60 to 80 degrees, and slowly add concentrated sulfuric acid with a concentration of 94% until sufficient. Add slowly and stir. Add up to 1200 milliliters of potassium sulfate or completely dissolve, and the solution will appear dark red in color. At this time, the rate of adding concentrated sulfuric acid can be accelerated until it is completely added. If there are still undissolved crystals after adding concentrated sulfuric acid, they can be heated until dissolved. The function of cleaning solution is to remove general pollutants, grease, and metal particle impurities on the wall of stainless steel filter cartridge, and it can effectively kill the bacteria and microorganisms that grow on the filter cartridge and damage the heat source. If the filter element has been alkaline washed before, the alkaline solution must be washed first, otherwise fatty acids will precipitate and contaminate the filter elementSFN-02-60K SFN-02-100K SFN-02-150K SFN-02-200K
