Replace HC9020 series hydraulic oil filter element

This replacement HC9020 series hydraulic oil filter element is a highly adaptable replacement component developed for medium and high pressure industrial hydraulic systems. It strictly aligns the installation dimensions, oil flow parameters, and sealing standards of the original series filter element, and can be directly replaced without making any changes to the original filter seat or pipeline structure. On the premise of ensuring 100% compatibility with the original system operating logic, the filter material layout and support structure have been optimized for working conditions, providing stable impurity interception ability in long-term continuous operation of hydraulic circuits, and building a solid oil purification defense line for the reliable operation of system core components.

The HC9020 series hydraulic oil filter element is replaced by a multi-layer gradient composite filter material structure, gradually achieving large particle pre interception, fine particle deep adsorption, and high-precision final filtration from the outer coarse filter layer to the inner fine filter layer. The internal structure is equipped with a high-strength perforated support skeleton, which can withstand the instantaneous high-pressure impact caused by frequent system start stop and load changes. The seamless hot melt sealing process is used at the connection between the end cap and the filter layer to completely prevent unfiltered oil from leaking. The filtration accuracy covers the commonly used range of 3 μ m to 12 μ m. All products in the series have passed long-term high-temperature circulation fatigue testing, and can maintain stable oil flow efficiency and filtration accuracy under high load continuous working conditions without problems such as filter layer deformation and detachment.

The HC9020 series hydraulic oil filter can be widely adapted to the main hydraulic circuit of heavy construction machinery, effectively intercepting metal debris, sealing debris, and oxidized gum in the oil, and protecting core actuating components such as pump valves and oil cylinders; It can also be applied to servo hydraulic stations in the metallurgical industry to maintain oil cleanliness in continuous high load production environments and avoid servo valve jamming affecting production accuracy; At the same time, it can be matched with mining equipment, wind power main control hydraulic system, large machine tool hydraulic power unit, port lifting machinery and other scenarios, providing a universal and reliable oil purification and replacement solution for various medium and high pressure hydraulic systems.

Compared to conventional replacement hydraulic oil filter cartridges of the same specifications, this HC9020 series hydraulic oil filter cartridge reduces oil resistance by 18% under the same filtration accuracy, which can reduce useless energy consumption of the system and lower the operating load of the hydraulic pump; The gradient filter material structure increases the pollutant holding capacity by more than 35%, effectively extending the filter element replacement cycle and reducing the frequency of daily equipment maintenance; The overall anti pressure impact performance has been greatly optimized, which can cope with instantaneous high pressure fluctuations in the system and avoid secondary oil pollution caused by filter layer damage; The standardized quick installation structure eliminates the need for specialized tools for replacement operations, significantly reducing equipment downtime and maintenance time, and lowering comprehensive operation and maintenance costs for users from a long-term usage perspective.

If the system pressure increases abnormally after replacing the HC9020 series hydraulic oil filter element installation, first check whether the installation direction of the filter element is correct, confirm whether the end cap seal is offset or deformed by compression, clean the residual impurities in the filter seat, and reinstall to restore normal operation; If the cleanliness of the filtered oil does not meet the standard, it is necessary to check whether the filtering accuracy gear is selected incorrectly, investigate whether there are sealing leaks caused by external impurities entering the system, replace the corresponding precision filter element, and seal the leakage point to solve the problem; If the service life of the filter element is significantly short, it is necessary to check whether the hydraulic oil has oxidized or deteriorated, confirm whether there are a large number of metal particles produced by abnormal wear in the system, replace the deteriorated hydraulic oil, and inspect the worn parts. After that, the filter element can restore its normal service life.
