Liugong SP293501 Fuel Coarse Filter Assembly: Filters impurities, separates water, resists clogging, and protects the fine filter, thereby extending the lifespan of the fuel injectors.

When construction machinery is operating on a construction site, impurities and moisture in the fuel pose a threat to the engine. “ The Invisible Killer — Rust and sand particles mixed into diesel during transportation and storage, as well as dust entrained when refueling, can quickly clog the fuel fine filter, leading to insufficient fuel supply and reduced engine power. Unfiltered large-particle impurities that enter the fuel injectors can act like... “ Dagger ” The same worn-out needle-valve components can lead to poor fuel atomization and a sharp increase in fuel consumption. Moisture in the fuel can also corrode the fuel injection system, making a single injector repair cost several thousand yuan. LiuGong. SP293501 Fuel coarse filter assembly, custom-made by the manufacturer. “ Front-end impurity filtration core ” Specifically designed to intercept large particulate impurities and moisture, it establishes the first line of defense for the fuel system, reduces fine-filter wear, and safeguards the safety of the fuel injection system.

Factory-precise fit: perfectly seamless, filtering out impurities with no leaks.

The fitting accuracy of the fuel coarse filter directly determines the filtration performance, LiuGong. SP293501 Developed entirely based on the original manufacturer’s fuel line parameters: The filter cartridge’s outer diameter and interface threads precisely match the fuel lines, with an error margin of less than— 0.1mm After installation, it seamlessly connects to the pipeline, avoiding non-genuine assemblies. “ Gap oil leakage ” or “ Mixed oil flow around ” potential hazards; the oil inlet and outlet are equipped with built-in sealing O-rings made of oil-resistant nitrile rubber, which tightly fill the gaps under pressure, achieving a sealing pressure of... 1.2MPa Ensure fuel. 100% Filtered through filter media; the assembly comes with a built-in positioning bracket that fits precisely into the engine compartment mounting location, ensuring no shaking or shifting during bumpy operations. Maintenance personnel can use standard tools. 20 The entire replacement process can be completed in just minutes, allowing fuel protection to be restored during construction breaks.

Dual-core filtration and water separation: Pre-filter reduces load, significantly lowering pressure on the fine filter.

For fuel “ Diverse, water-containing ” the dual problem, SP293501 Adopt “ Composite filter material + Separation structure ” Dual-layer design: The filter material is a composite of high-strength glass fiber and hydrophobic nonwoven fabric, specifically designed to capture particles with diameters greater than... 10 μm large particulate impurities such as rust and sand grains, with a filtration efficiency of 95% Above, reduce the filtration burden of fine filtration at the source; additionally, a hydrophobic layer is incorporated into the filter media to leverage the density difference between oil and water. “ Fuel filtration and water separation ” , with a separation efficiency of 90% The separated water can be quickly drained through the bottom drain valve, preventing moisture from causing corrosion to the fuel injectors and fuel pump. The filter material used is... “ Folding structure ” Dust-holding capacity is improved compared to conventional flat filter media. 60% This reduces the increase in fuel supply resistance caused by impurity blockage, ensuring smooth fuel delivery to the engine.

Anti-clogging and durable upgrade: Suitable even for highly contaminated environments. “ Can handle it. ”

Faced with scenarios where construction sites have high levels of fuel impurities and inconvenient replacement procedures, SP293501 Specialized reinforcement for durability: The filter cartridge is molded in one piece from high-strength engineering plastic, and its surface has undergone antistatic treatment to prevent static electricity generated by fuel flow from attracting impurities. Minor accumulations of debris can be naturally washed away by the fuel flow. The edges of the filter media are sealed using hot-melt adhesive instead of traditional stitching, effectively eliminating the risk of impurities leaking through needle holes while enhancing the overall integrity of the filter media and resisting deformation caused by fuel pressure surges. The assembly features a built-in pressure-warning device that triggers a dashboard alert when the filter media becomes clogged and the pressure rises, thereby preventing potential damage. “ Wasteful and indiscriminate replacement ” or “ Blockage and oil shortage damage the machine. ” , with a longer service life compared to conventional coarse filters. 50%。

All-condition weather resistance: Oil filtration remains stable even in harsh environments.

From -30℃ From the frigid construction site in Northeast China to 45℃ the southern scorching mining area, SP293501 All can perform their duties reliably: The filter media is added with low-temperature-resistant additives, ensuring no brittleness or cracking even in extremely cold environments. Fuel flowability remains unaffected, guaranteeing normal fuel supply during cold starts. The filter cartridge’s temperature resistance range reaches... -40℃ To 100℃ Under the high-temperature baking of the engine compartment, it remains deformation-free and does not age. For environments with high humidity tunnels and salty sea-air conditions, an additional anti-corrosion coating is applied to the surface of the filter cartridge, and salt-spray testing has been conducted. 720 It is corrosion-free for hours, preventing filter cartridge damage that could lead to filtration failure, and ensuring fuel cleanliness even under a wide range of extreme operating conditions.

Provincial-level device protection value: One-time selection, multiple savings.

SP293501 of the “ Provincial-level attribute ” This is reflected throughout the entire lifecycle: As a pre-filtration stage, it can extend the replacement cycle of the fine filter to its original length. 2 Double, replace annually based on fine filtration. 4 With this calculation, annual savings on refined filter procurement costs exceed... 800 Yuan: Highly efficient filtration and water separation reduce nozzle wear, thereby extending the nozzle's service life. 30% The cost of a single fuel injector repair exceeds... 3000 In the long term, consistent use can significantly reduce major overhaul costs. The stable fuel supply ensures more thorough fuel atomization in the engine, thereby lowering the combined fuel consumption per 100 kilometers. 3% Based on the device's average daily fuel consumption 100 Gasoline, diesel 8 Yuan / Calculated based on fuel efficiency, you can save nearly 10,000 yuan in fuel costs per year; the pressure-warning design prevents unnecessary shutdowns and replacements, thereby reducing losses due to work interruptions.

Rigorous quality control provides a safety net: Factory-guaranteed, zero-risk.
