Maintenance & Care Recommendations

Proper maintenance of engineering parts is essential to extend their service life and ensure equipment performance. Below are practical maintenance suggestions:

• Regular Inspection: Check parts such as high-pressure hoses (A1311-6000), seals (8E9649), and gaskets (36001-0203) for signs of wear, leakage, or deformation every 500 operating hours. Replace damaged parts in a timely manner to avoid equipment failure.

• Cleaning & Filtration: Replace filter elements (477556, 134-6307, DQ70BS TFX-250×80 5126070060) every 1000 operating hours or as recommended by the equipment manual. Keep the filtration system clean to prevent impurities from entering key components.

• Lubrication: Apply appropriate lubricating oil to moving parts such as clutch gear rings (JC28/11-06-19), input shafts (P2400031AA), and bearings (6839821) to reduce friction and wear. Use lubricants that meet OEM specifications.

• Storage: Store spare parts in a dry, clean, and well-ventilated environment. Avoid direct sunlight, high temperature, and humidity to prevent rust and damage. For seals and gaskets, store them in sealed packaging to avoid aging.

• Professional Installation: Ensure parts are installed by trained maintenance engineers. Follow the OEM installation guidelines to avoid incorrect installation that may cause part damage or equipment failure.

On-Site Fault Repair Cases

Below are 3 real on-site fault repair cases, showing how our parts solve practical problems for customers:

Case 1: Drilling Rig Hydraulic System Leakage

Equipment: ZJ70 drilling rig
Fault: Hydraulic oil leakage from the high-pressure hose assembly, leading to reduced hydraulic pressure and inability to lift the drill string.
Diagnosis: The original high-pressure hose (non-our product) was worn and cracked due to long-term use in high-pressure and dusty environments.
Solution: Replaced with our High Pressure Hose Assembly A1311-6000, which is made of wear-resistant and high-pressure-resistant material. After installation, the hydraulic system pressure returned to normal, and no leakage occurred during subsequent operation.
Result: The drilling rig resumed normal operation within 2 hours, avoiding 12 hours of unplanned downtime and reducing economic losses.

Case 2: Engine Power Reduction

Equipment: Heavy-duty truck with Allison CLBT 754 DB transmission
Fault: The engine power decreased significantly, and fuel consumption increased. The exhaust pipe emitted black smoke.
Diagnosis: The exhaust valve (original part) was worn and could not close tightly, leading to gas leakage and incomplete combustion.
Solution: Replaced with our Exhaust Valve 115-2367, which has a precise sealing structure and heat-resistant material. After replacement, the engine’s exhaust system worked normally, and combustion efficiency was restored.
Result: Engine power returned to the original level, fuel consumption decreased by 8%, and the truck resumed normal transportation tasks.

Case 3: Filter Blockage Causing Pump Failure

Equipment: Industrial boiler WNS2-1.25-Y
Fault: The boiler’s water pump failed to start, and the filter element was severely blocked by impurities.
Diagnosis: The original filter element had low filtration precision and was easily blocked by sediment and impurities in the water, leading to pump overload and failure.
Solution: Replaced with our Filter Element 477556, which has high filtration precision (80μm) and large dirt-holding capacity. Cleaned the water pipeline and reset the pump.
Result: The water pump started normally, and the filter element’s service life was extended by 50% compared to the original part. The boiler operated stably for 3 months without further faults.
