• Bearings & Transmission Parts: Add lubricating oil (matched with the equipment manual) every 500 operating hours for bearings (e.g., QC010014 bearing 6211, BR1124 Fanshaft Bearing). Avoid over-lubrication or under-lubrication; check for abnormal noise or vibration during operation, which may indicate bearing damage.

• Filters: Replace the filter element (e.g., BLX-400 X5X, NJU-250X180F) every 2,000 operating hours or when the pressure difference exceeds 0.3MPa. Clean the filter housing regularly to prevent impurity accumulation; use only genuine filter elements to avoid damaging the hydraulic or engine system.

• Hydraulic & Pneumatic Parts: Inspect hydraulic pumps (A10VS018DFR1) and valves (H03-1050-010) every 1,500 operating hours for oil leakage or blockage. Flush the hydraulic system every 6 months to remove sludge and impurities; ensure the working medium meets the specified viscosity and cleanliness requirements.

• General Care: Store parts in a dry, clean, and ventilated environment, avoiding direct sunlight or moisture. For long-term storage, apply anti-rust oil to metal parts (e.g., piston rods, flanges) to prevent corrosion.

On-Site Fault Maintenance Cases

Below are 3 real on-site fault cases, providing practical reference for equipment maintenance and part replacement, helping you quickly identify and solve problems:

Case 1: Drilling Rig Hydraulic System Leakage

Equipment Model: ZJ-50/315 drilling rig
Fault Phenomenon: Hydraulic system pressure drop, serious oil leakage at the cylinder liner seal, resulting in reduced drilling efficiency.
Root Cause: The original cylinder liner seal (non-genuine) was made of ordinary material, which was corroded by acid drilling fluid and worn out after 3,000 operating hours.
Solution: Replace with our GH3161-05.14G cylinder liner seal (corrosion-resistant GH3161 alloy material). After replacement, the seal passed a 72-hour pressure test (31.5MPa) without leakage, and the service life was extended to 8,000 operating hours. The drilling rig returned to normal operation, reducing maintenance downtime by 6 hours.

Case 2: Excavator Travel Motor Failure

Equipment Model: ZX870-5G excavator
Fault Phenomenon: The excavator travels slowly, with abnormal noise from the travel motor, and eventually fails to move.
Root Cause: The original travel motor (MSF340ⅤP-F13) had internal component wear, and the transmission efficiency dropped to 85%, which could not meet the load requirements.
Solution: Replace with our genuine travel motor for ZX870-5G MSF340ⅤP-F13, which adopts precision-machined internal components and high-strength materials. After replacement, the travel speed returned to the standard value, the noise was reduced to ≤70dB, and the transmission efficiency reached 98%. The excavator resumed normal construction, avoiding project delays.

Case 3: Industrial Pump Ripple and Vibration

Equipment Model: QWS-2500SD pump
Fault Phenomenon: The pump had severe ripple and vibration during operation, leading to loose connections of surrounding pipelines and shortened pump service life.
