answer 1:

Because the paper filter element is spliced in the process of use, the service life is shortened. In order to overcome this disadvantage, the service life can be increased by 2 ~ 3 times by adding lining mesh or lining inner frame on the inner wall of the filter element or rolling corrugated on the surface of the filter paper. The paper filter element is usually not maintained. Replace it with a new core after it is blocked. However, sometimes because the filter element equipment is not available for the moment, the used paper core can also be cleaned and maintained according to certain operating procedures. Gently clean it in kerosene or gasoline with a soft brush, blow it back with air, and then continue to use. The paper filter element is usually installed in the main oil passage for full flow filtration, but it can also be installed on the shunt branch parallel to the main oil passage for shunt filtration. 2. Sawdust filter element sawdust filter element is also called sawdust filter element. Sawdust of red and white pine is used as raw material, sorted by screen, mixed with pulp molding, dried and dehydrated. Sawdust filter element has the advantages of single raw material variety, simple process operation and good filtration fineness. However, because the filter element has dense structure, large resistance and short primary service life, it can only be used for shunt filtration. 3. The plastic filter element is made of engineering plastics with certain viscosity, heat resistance and corrosion resistance, which is molded and fired to form a porous filter element with deep filtration function. This filter element equipment can continue to be used after maintenance according to certain procedures. 4. The metal mesh filter element uses 100 ~ 200 mesh phosphor copper wire mesh or brass wire mesh per inch as the filter element material. The filter element has cylindrical and laminated shapes. The metal mesh filter element has the advantages of large flow, small resistance, reliable function and easy cleaning. It is often used for full flow filtration. The filter fineness depends on the mesh size. In recent years, due to the development of chemical industry, nylon material has been used as the framework to support the filter screen, and nylon cloth has been used to replace the metal mesh. This structure saves non-ferrous metals and is conducive to the development of production. 5. The wound filter element is rolled with steel strip or brass strip. There is a convex shape on the surface every certain distance, and the convex height is 0.04 ~ 0.09 mm. Wrap this metal strip around a corrugated cylinder with grooves on the surface. The bottom surface of the previous strip contacts the convex surface of the next strip, forming many gaps, which is the wound slot filter element. 6. The chip filter element is punched into three shapes of steel sheet, filter sheet, spacer and scraper with thin steel belt. The thickness of the filter is 0.1 ~ 0.2mm, and the thickness of the spacer and scraper is 0.06 ~ 0.08mm. The filter element is composed of several filter pieces and spacer pieces stacked alternately. The scraper blade is fixed on another pillar, and each scraper blade is inserted between the two filter blades. When the filter element is rotated, the dirt attached to the edge of the filter element is scraped off by the scraper blade and settled at the bottom of the filter housing, which can be discharged through the sewage plug. The rotation of the filter element can be manual, foot movement or mechanical transmission. 7. The centrifugal filter uses the pressure energy of the lubrication system to generate a reaction torque from the oil passing through the nozzle to drive the rotor to rotate. Under the action of centrifugal force, the oil in the rotor separates solid impurities and accumulates on the inner wall of the rotor. The oil in the center of the rotor becomes clean and flows back to the oil pan from the nozzle. This is the working principle of centrifugal filter. If the oil in the center of the rotor is directly introduced into the main oil passage, it becomes a full flow centrifugal filter, and the above structure is called a split flow centrifugal filter. Sincerely hope to cooperate with you
