1. It can classify and filter pollutants in hydraulic oil, such as ferromagnetic particles, which can be accurately adsorbed by magnetic filters to prevent them from entering the hydraulic valve and interfering with the normal movement of the valve core, ensuring the control accuracy of the valve. The rubber debris filter in the hydraulic system, caused by aging and wear of seals, can efficiently intercept and prevent debris from blocking the throttle hole, maintaining stable system flow. Filters can filter out gelatinous substances after hydraulic oil oxidation. According to relevant research, these gelatinous substances will increase the viscosity of the oil. Timely removal by filters can ensure that the viscosity of the oil is within the appropriate range, which is beneficial for the normal operation of the system. It can remove moisture from hydraulic oil. Generally speaking, when the moisture content in the oil exceeds 0.1%, it may cause metal parts to rust. The filter separates moisture through special filter material to protect system components.
2. Fiber impurities in the oil can be filtered out, which may come from sealing materials, filter cartridge detachment, etc., to prevent them from winding around the oil suction port of the hydraulic pump and avoid poor oil suction. Filters have a good filtering effect on dust in oil, for example, in some hydraulic equipment used for outdoor operations, they can block a large amount of dust from entering the system and reduce component wear. It can filter out metal abrasive particles generated by friction in hydraulic systems, such as tiny metal particles generated by gear meshing in gear pumps, to prevent them from entering other precision components. For microorganisms in oil, filters also have a certain filtering ability. The growth of microorganisms can change the chemical properties of the oil, and filters can suppress this situation.
3. It can remove the decomposition products of additives in hydraulic oil. Some additives will decompose after long-term use, and the filter can filter out these decomposition products to maintain stable oil performance.
