Description

Technical Field

[0001] The utility model relates to an oil filter element, in particular to a laminated hydraulic oil filter element. Background Art

[0002] During the operation of hydraulic oil, mechanical oil, cooling oil and other lubricating oils, water, gas, volatile substances and impurities will inevitably mix into the lubricating oil for various reasons, accelerating the oxidation of the oil, and promoting the formation of foam, scale and sludge, reducing the lubrication, heat dissipation, dispersion and cooling properties of the oil. At the same time, it causes rust and wear of metal parts, affecting the normal operation of the hydraulic system, power system and lubrication system. In order to ensure the performance and reliability of the hydraulic system, the cleanliness of the oil is required to be higher and higher. The hydraulic oil filter can not only be used as a special equipment for filtering new oil injected into the hydraulic system, but also as a special equipment for regularly filtering pollutants in the system medium. It can help users better deal with pollutants in the hydraulic system and effectively ensure the cleanliness of the oil, thereby extending the service life of hydraulic components and ensuring the normal operation of the system.
