4. Function Description

Each component of our LUC, LUCA, LUCB oil filter carts and matching filter element has a critical function that directly impacts oil purification efficiency, equipment protection, and service life. Understanding these functions helps you select the right products, use them correctly, and troubleshoot faults efficiently—ensuring your industrial machinery operates at peak performance:

4.1 Oil Filter Cart Core Functions

• Oil Suction & Circulation: The built-in high-pressure pump (rated pressure 0.6-1.2MPa) suctions contaminated oil from hydraulic or lubrication systems, circulates it through the filter element, and returns purified oil to the system. The pump’s flow rate is matched to the cart’s model (16-100L/min), ensuring efficient oil circulation without causing system pressure loss.

• Precision Filtration: The filter element (matching the cart’s filtration precision) removes solid contaminants (dust, metal particles, sludge, carbon deposits) from the oil—particles as small as 3μm can be effectively filtered. This prevents contaminants from entering machinery components (valves, bearings, cylinders), reducing wear, blockages, and failure rates.

• Contaminant Collection & Indication: The filter element’s dirt-holding chamber collects filtered contaminants, preventing them from re-entering the oil. Most models are equipped with a pressure gauge that indicates the filter element’s contamination level—when the pressure exceeds the rated value (0.2-0.3MPa), it signals that the filter element needs to be replaced, ensuring continuous filtration efficiency.

• Special Function Optimization: “W” (waterproof) variants feature sealed electrical components and waterproof casings, preventing water ingress in humid or outdoor environments; “Q” (anti-corrosion) variants use stainless steel casings and anti-corrosion coatings, resisting damage from corrosive gases or liquids in chemical or marine environments.

4.2 Filter Element Core Functions

• Contaminant Retention: The filter element’s filter medium (glass fiber, cellulose, synthetic fiber) has a porous structure that traps solid contaminants while allowing oil to pass through. Different filter media are tailored to different filtration precisions and working conditions—e.g., glass fiber for fine filtration, synthetic fiber for harsh environments.

• Oil Purification & Protection: By removing contaminants, the filter element maintains oil cleanliness, preventing oil degradation (oxidation, viscosity increase) and ensuring the oil’s lubricating, cooling, and sealing properties are maintained. This extends the service life of the oil itself (reducing oil replacement frequency) and protects machinery components.

• Pressure Resistance & Stability: The filter element’s skeleton is made of high-strength plastic or metal, ensuring it can withstand the cart’s operating pressure (0.6-1.2MPa) without deformation or damage. The seal ring (equipped on all filter element) prevents unfiltered oil from bypassing the filter element, ensuring all oil passes through the filtration medium.

8. On-Site Fault Maintenance Cases

The following 4 real on-site fault cases are common problems encountered in LUC, LUCA, LUCB oil filter cart operation (covering all three series and matching filter element). Each case includes fault phenomenon, judgment, maintenance method, and preventive measures—providing practical reference for on-site maintenance personnel. All maintenance uses our genuine products to ensure stable, long-lasting results:

Case 1: LUCA-16x3W Filter Cart Pressure Too High & Filtration Efficiency Decline

• Fault Phenomenon: A construction site LUCA-16x3W (16L/min, 3μm, waterproof) filter cart operates with a pressure gauge reading of 0.4MPa (exceeding the safe limit of 0.3MPa), and the purified oil still contains visible contaminants—leading to increased wear on the hydraulic system of the construction machinery.

• Fault Judgment: On-site inspection found that the matching CXXA2-16x50 filter element was severely clogged (used for 250 working hours), with a large amount of dust and metal particles accumulated in the dirt-holding chamber. The filter element’s seal ring was slightly damaged, causing unfiltered oil to bypass—resulting in poor filtration efficiency and high pressure.

• Maintenance Method: Stop the cart and disconnect the power supply; open the filter housing and remove the clogged filter element; clean the housing’s inner surface with a soft cloth; replace the damaged seal ring and install a new genuine CXXA2-16x50 filter element (matched to LUCA-16x3W); restart the cart—pressure drops to 0.2MPa, and purified oil is free of contaminants, restoring filtration efficiency.

• Preventive Measures: Check the pressure gauge every 2 hours during use; replace the filter element every 200 working hours (or when pressure exceeds 0.3MPa); inspect the seal ring for damage when replacing the filter element, especially in dusty construction site environments.

Case 2: LUC-40x5 Filter Cart Pump Noise Abnormal & No Oil Output

• Fault Phenomenon: A factory LUC-40x5 (40L/min, 5μm) filter cart makes abnormal grinding noise when started, and no oil is output from the cart—preventing routine oil purification of the factory’s lubrication system.

• Fault Judgment: Inspection shows that the pump’s inlet hose is clogged with large contaminants (sludge), causing the pump to idle and lack oil lubrication—leading to bearing wear and abnormal noise. The filter element (CXXA1-40x80) is also slightly clogged, but the main fault is the inlet hose blockage.

• Maintenance Method: Stop the cart and disconnect the power supply; remove the inlet hose and clean it thoroughly to remove sludge and contaminants; replace the slightly clogged CXXA1-40x80 filter element with a genuine one; add lubricating oil to the pump bearings; reconnect the hose and restart the cart—noise disappears, and oil output returns to normal (40L/min).

• Preventive Measures: Clean the inlet hose and filter screen (installed at the inlet) every 100 working hours; check the oil system for sludge accumulation regularly; replace the filter element on schedule to avoid clogging and pump damage.

Case 3: LUCB-63x10Q Filter Cart Oil Leakage & Corrosion

• Fault Phenomenon: A chemical plant LUCB-63x10Q (63L/min, 10μm, anti-corrosion) filter cart has oil leakage at the filter housing connection, and the casing has slight corrosion—posing a safety risk in the chemical environment.

• Fault Judgment: The filter housing’s sealing gasket is aged and damaged (used for 800 working hours), causing oil leakage; the casing’s anti-corrosion coating is scratched (due to improper cleaning), leading to slight corrosion—common in chemical plants with corrosive gases.

• Maintenance Method: Stop the cart and disconnect the power supply; drain the oil in the cart; replace the aged sealing gasket with a genuine fluororubber gasket (anti-corrosion, oil-resistant); clean the casing with neutral cleaning solvent and repair the scratched anti-corrosion coating with matching paint; reinstall the filter housing and add oil; restart the cart—oil leakage stops, and corrosion is prevented from spreading.

• Preventive Measures: Inspect the filter housing’s sealing gasket every 500 working hours; replace it every 800 working hours; clean the casing with neutral cleaning solvent (avoid abrasive agents); check the anti-corrosion coating regularly and repair scratches promptly.

Case 4: CWUA-40x100-J Filter Element Damage & Oil Contamination

• Fault Phenomenon: A precision machinery factory uses a LUCA-40x10 (40L/min, 10μm) filter cart with a CWUA-40x100-J filter element for high-precision hydraulic oil purification. The hydraulic system’s valves are worn abnormally, and inspection shows the oil contains small particles—indicating the filter element is damaged.

• Fault Judgment: The CWUA-40x100-J filter element’s glass fiber filter medium is damaged (due to excessive pressure caused by delayed replacement), allowing small particles to pass through—leading to oil contamination and valve wear. The pressure gauge was not checked regularly, so the high pressure was not detected in time.

• Maintenance Method: Stop the filter cart and hydraulic system; replace the damaged CWUA-40x100-J filter element with a genuine one; purify the hydraulic system’s oil with a new filter element; inspect and repair the worn valves; restart the system—oil cleanliness meets NAS 6 grade, and valve wear is prevented.

• Preventive Measures: Check the pressure gauge every hour during use for high-precision applications; replace the CWUA series filter element every 200 working hours (or when pressure exceeds 0.3MPa); conduct regular oil cleanliness tests to ensure filtration efficiency.
