Liugong SP234061 Hydraulic Oil Tank Breather Filter Element: Filters out impurities to protect the hydraulic fluid and ensure the efficient operation of the hydraulic system.

In construction machinery “ Power core — In hydraulic systems, the breather filter element of the hydraulic oil tank is often overlooked yet critically important. “ Protective barrier ” When the equipment is operating in mines or muddy construction sites, the hydraulic oil tank needs to use a breather to balance the internal and external pressures (just as...). “ Breathing ” ), if the filter element fails to filter effectively, dust, muddy water, and metal debris will follow. “ Inhale ” Entering the fuel tank and contaminating the hydraulic oil can lead to malfunctions such as valve group sticking, hydraulic pump wear, and cylinder leakage, directly causing equipment downtime and a sharp increase in maintenance costs. LiuGong. SP234061 Hydraulic oil tank breather filter element, custom-made by the original manufacturer. “ Hydraulic Oil Guardian ” With its advantages of precise dirt filtration and prevention of backflow and leakage, it provides a solid foundation for hydraulic systems. “ First line of defense ” Ensure the cleanliness of the hydraulic oil and the stability of system operation.

Factory-precise fit: tightly matches the fuel tank interface, ensuring no dead corners for dirt accumulation.

The sealing and fit of the hydraulic oil tank breather directly determine its anti-contamination performance, LiuGong. SP234061 Development of breather interface parameters for hydraulic oil tanks specifically tailored to particular aircraft models: The filter element’s installation thread specifications and sealing surface diameter are precisely matched to the tank’s interface, with tolerances kept within... 0.1mm Inside, tight fitting can be achieved simply by hand-tightening—no need to wrap additional PTFE tape. The height of the filter cartridge housing and the diameter of its ventilation holes precisely match those of the original respirator assembly, ensuring smooth airflow and balanced pressure while also preventing the use of non-original filter cartridges. “ Dimensional deviations cause gaps that allow dirt and contaminants to leak through. — Even the diameter 0.3mm The dust particles cannot penetrate through the interface gap either; it comes with a built-in positioning latch design, allowing maintenance personnel... 1 The replacement can be completed within minutes, allowing for rapid restoration of protection even during emergency repairs on construction sites.

Three-stage dirt filtration: first block, then trap—keeping hydraulic oil clean and protected.

For construction machinery operations “ Large particles, numerous and diverse microimpurities. ” the pollution characteristics, SP234061 Adopt “ Three-stage composite filtration ” Structure that achieves all-dimensional interception of pollutants: The outer layer is a coarse filtration layer made of wear-resistant metal mesh, which can efficiently block particles with diameters greater than... 50 μm Large particulate impurities such as sand, gravel, and dead leaves are prevented from impacting and wearing down the inner filter material. The middle layer is a fine filtration layer made of glass fibers, which utilizes a micro-porous structure formed by the interweaving of fibers to... 5–50 μm The dust and metal chip interception efficiency reaches 98% Above, this precision precisely covers the impurity range where hydraulic systems are most vulnerable. The inner layer is a hydrophobic and breathable membrane that allows air to pass through while effectively blocking the penetration of mud, water, and oil mist. At the same time, it possesses a certain oil-gas separation capability, reducing volatile losses of hydraulic oil. This constitutes a three-stage filtration system. “ Gradient Protection Net ” Ensure that the air entering the fuel tank is clean and free of contaminants.

Anti-backflow and anti-leakage design: Keeps protection running even when the machine is stopped, eliminating secondary contamination.

Pressure fluctuations during the start-up and shutdown of hydraulic systems can easily trigger... “ Inhalation of contamination ”，SP234061 Targeted design with dual protection: A built-in one-way check valve automatically closes when the equipment is shut down and the pressure inside the fuel tank drops below ambient pressure, preventing contaminated air from flowing back into the tank and completely eliminating the shortcomings of conventional filter elements. “ Out of service and defenseless ” potential hazards; the connection between the filter element and the housing is molded using oil-resistant sealant, ensuring a seamless joint with no gaps. Meanwhile, the bottom of the housing is equipped with a drainage groove that allows rainwater to be quickly discharged even if it splashes during operation, preventing water accumulation from seeping into the filter element or flowing along the joints into the fuel tank. This... “ Start-stop dual protection ” Design ensures that the hydraulic system remains clean and protected under all operating conditions.

Oil-resistant and corrosion-resistant reinforcement: Perfectly suited for hydraulic environments, offering durability and peace of mind.

The area around the hydraulic oil tank has long been subject to hydraulic oil evaporation and temperature fluctuations. SP234061 Specialized optimization in materials: The filter cartridge housing is oil-resistant. ABS Engineering plastic, immersed in hydraulic oil 720 It exhibits no swelling or deformation over time and is resistant to the corrosive effects of hydraulic oil volatiles. The glass fiber filter material has undergone anti-aging treatment, and... -30℃ To 100℃ It maintains stable filtration performance within a wide temperature range, making it suitable for both the severe cold of northern regions and the high-temperature environments found in engine compartments. The hydrophobic membrane is made of polytetrafluoroethylene (PTFE), which not only repels water and oil but also withstands minor pressure surges from hydraulic systems, thereby preventing membrane damage that could lead to filtration failure. In high-dust mining environments, its effective service life is significantly longer than that of conventional filter elements. 40% Significantly reduce the frequency of replacements.

End-to-end quality control: Benchmarking against hydraulic standards, with traceable quality.

LiuGong vs. SP234061 Execute “ Hydraulic System Level ” Strict quality control: The filter material must pass. 800 Hourly dust load testing and hydraulic oil compatibility testing are conducted to ensure that the filtration accuracy and corrosion resistance meet the standards; filter elements from each batch are sampled for testing. “ Pressure cycling test — Simulate pressure fluctuations during the start-up and shut-down of the hydraulic system to verify the sealing performance of check valves and the stability of filter media; the finished product stage must pass through... “ Impurity Penetration Test ” Under high-pressure airflow, standard impurities are introduced to ensure there is no leakage or penetration. Each filter cartridge comes with an original factory traceability code; scanning this code allows you to check the production batch and inspection reports, completely eliminating counterfeit products. “ Filtering impurities is ineffective. ” Risk of hydraulic system failure caused by this.

For construction machinery, the lifespan of the hydraulic system depends on the cleanliness of the hydraulic oil, and... SP234061 It's about safeguarding this purity. “ First sentry post ” Choose LiuGong. SP234061 The hydraulic oil tank breather filter element is not just a small component replacement—it’s also a thoughtful choice for core components such as the hydraulic pump, valve group, and cylinders. “ Security Assurance — It precisely filters out contaminants to reduce oil fluid pollution, employs a reverse-design approach to prevent secondary contamination, and uses oil-resistant materials to extend service life—ultimately lowering equipment maintenance costs and minimizing downtime. When your equipment requires replacement of the breather filter element, SP234061 It will be the optimal solution that balances compatibility, protection, and cost-effectiveness, ensuring the efficient operation of hydraulic systems!
