Liugong SP114871 Oil-Water Separator Filter Element: Dual-Effect Dehydration and Impurity Removal—Ensuring Clean Fuel for Reliable Power Performance

In the fuel supply system of construction machinery, clean fuel is the foundation for the engine to stably deliver power. —— However, fuel is prone to absorbing moisture during storage and transportation, and dust and metal particles from the operating environment can also enter the system along with the fuel. If moisture and impurities are not effectively removed, they can cause wear on fuel injectors, failure of the fuel pump, and even lead to issues such as unstable engine idling, reduced power output, and excessive emissions—seriously impacting equipment operational efficiency and engine lifespan. LiuGong. SP114871 Oil-water separator filter element, custom-made by the original manufacturer for fuel. “ Purification Guardian ” With its efficient oil-water separation capability and precise impurity filtration performance, it establishes a double-layered clean defense for the fuel system.

Factory-precise fit: perfectly seamless, eliminating any leakage. “ Blind spot ”

Liugong SP114871 The design of the oil-water separator filter element is fully aligned with the fuel filtration system of the specific equipment model, seamlessly matching the original manufacturer’s standards in both external dimensions and interface specifications: The filter element’s height and outer diameter precisely match those of the oil-water separator housing, and the dimensions of the mounting clips and sealing O-rings are completely identical to those of the original components, allowing for direct installation without any additional adjustments—perfectly suited for ordinary maintenance personnel. 10  The replacement can be completed within minutes, significantly reducing equipment downtime. Even more crucially, the original manufacturer’s compatibility ensures that the filter element fits tightly against the sealing surface of the separator housing, completely eliminating the common issues associated with non-original filter elements. “ Fuel bypass ”  Question —— It prevents fuel containing moisture and impurities from directly entering the engine due to dimensional deviations, ensuring that every drop of fuel is thoroughly purified and providing the engine with a pure power supply.

High-efficiency oil-water separation: Precise dehydration to prevent moisture-related damage.

Regarding the hazards of moisture in fuel, LiuGong. SP114871 Oil-water separator filter element uses “ Multi-layer stereoscopic separation ”  Technology for efficient dewatering: The filter cartridge is equipped with a specialized hydrophobic separation medium, enabling— “ Gravity settling +  Adsorption interception ”  The dual-action mechanism causes moisture in the fuel to condense into large water droplets on the surface of the medium, which then flow along the medium layer toward the water-storage chamber at the bottom of the separator, making it easy to drain periodically. Meanwhile, the pore structure of the separation medium has been specially designed to effectively capture even tiny water molecules (with diameters smaller than ...) without impeding the flow of fuel. 5 μm )’s interception efficiency reaches 98% Furthermore, even when the fuel has a relatively high moisture content (such as during the rainy season or in humid environments), this system can effectively reduce the moisture level in the fuel, thereby preventing malfunctions caused by moisture, such as injector corrosion and cavitation in the fuel pump.

Precision impurity filtration: Micron-level interception, safeguarding fuel cleanliness.

In addition to efficient dehydration, LiuGong SP114871 The oil-water separator filter element also boasts excellent impurity filtration performance. It is designed to effectively remove common impurities found in fuel, such as dust, metal particles, and gum-like substances. “ Stepwise filtering ”  Structure: The outer layer is a high-strength pre-filter that can capture particles larger than... 20 μm large-particle impurities, reducing the load on the inner filtration layer; the middle layer is an ultra-fine fiber filtration layer, which... 5-20 μm The interception efficiency of tiny particles reaches 99.2% The above measures prevent impurities from scratching the fuel injectors and clogging the fuel lines. The inner layer is an adsorption-type filter that can capture viscous impurities such as gum and asphaltene generated by fuel oxidation, thereby preventing them from adhering to the surfaces of engine components. Even in dusty working environments like mines and infrastructure projects, this filter can consistently and reliably remove impurities, ensuring that the fuel entering the engine remains clean and free of contaminants.

Low-resistance flow design: Balances purification and power, without compromising fuel supply efficiency.

If the filter element of a conventional oil-water separator has excessively high filtration accuracy, it can easily increase the resistance to fuel flow, thereby affecting the fuel supply. Particularly under high-load engine operating conditions—such as heavy-load uphill driving or high-speed operation—it may lead to insufficient fuel supply and consequently reduced power output. LiuGong. SP114871 By optimizing the pore distribution of the filtration medium and the design of flow channels, the oil-water separator filter element reduces fuel flow resistance while ensuring both dehydration and filtration efficiency. 15% Above: The fiber arrangement of the filter medium has been optimized through hydrodynamic calculations to create smooth flow. “ Fuel passage ” The central tube of the filter element features a hollow design, which increases the fuel flow area and ensures that fuel flows rapidly under rated pressure, promptly providing the engine with an adequate fuel supply. Whether it's smooth fuel delivery during cold starts at low temperatures or sustained power output under high temperatures and heavy loads, this design strikes a perfect balance. “ Purification effect ”  With “ Fuel supply efficiency ” , without affecting the engine's power response speed.

Oil- and temperature-resistant material: Designed to handle harsh operating conditions and extend service life.

Considering the operating environment of the fuel system (fuel corrosion, temperature fluctuations), LiuGong. SP114871 The filter element of the oil-water separator has been specifically enhanced in material selection: The filtration medium has undergone oil-resistant impregnation, ensuring structural stability even when exposed to various types of fuels such as diesel and gasoline—no softening, no shedding, and preventing fiber from the filter material from contaminating the fuel system. The filter element’s skeleton is made of high-strength, oil-resistant plastic that has been subjected to high-temperature shaping treatment, enabling it to withstand fuel pressure surges and equipment vibrations without deforming and causing the filtration layer to shift. The sealing gasket is crafted from nitrile rubber, a material that is both oil-resistant and heat-resistant. - 40℃ To 120℃ Maintains elasticity within the specified temperature range, does not harden or leak oil over long-term use, ensuring the filter element’s reliability under all operating conditions of the equipment, and boasts an average service life that is significantly longer than that of non-original filter elements. 40% The above.

End-to-end quality control system: Original manufacturer’s standards—every single unit is... “ Reliable ”

LiuGong vs. SP114871 The oil-water separator filter element undergoes comprehensive quality control throughout the entire process—from raw materials to finished products: The filtration medium must pass both oil-water separation efficiency tests and oil resistance tests to ensure that its dehydration and filtration performance meets the required standards. During production, random samples are taken from each batch for filtration accuracy testing (using the particle counting method to verify the impurity interception rate) and flow resistance testing, guaranteeing stable performance. Before the finished products leave the factory, they must also undergo high-temperature and high-pressure sealing tests (at...). 1.2  Twice the rated pressure, 100℃ Hold pressure at oil temperature. 30  No leakage within minutes) and life simulation testing (cyclic filtration in fuel containing moisture and impurities) 500  hours, verifying performance degradation). If any single test fails to meet the standard, the entire batch must be reworked to ensure that every single unit reaching the market... SP114871 The oil-water separator filter elements all meet the original equipment manufacturer (OEM) standards of LiuGong, providing optimal performance for the fuel system. “ Safe and reliable ”  Purification and assurance.
