Maintenance & Care Recommendations

Proper maintenance and care can significantly extend the service life of parts, reduce equipment downtime, and lower maintenance costs. Below are practical, easy-to-follow recommendations for on-site teams:

Daily Inspection

Check the condition of 3J1907 O-rings, ZJ70 LT07MKA-2X brake valves, WNS2-1.25-5Y pressure gauges, and hydraulic seals daily. Ensure there is no looseness, leakage, or damage. For filters (5I8670, WU-160×80-J), check for clogging or wear—replace them immediately if issues are found to avoid component damage. Inspect safety gears (BK-0-6 C) and brake shoes for proper operation.

Regular Cleaning & Replacement

Replace pilot filters (5I8670) and diesel filters (5400150039) every 25-30 operation hours to maintain fluid cleanliness. Clean 3112mm GS605F PDC drill bits regularly to remove debris, ensuring drilling efficiency. Replace dynamic friction discs (508459) and oil seals (CS33001-0308) if signs of wear are present, ensuring brake system and hydraulic system performance. Clean air conditioner external motors (YDK750-6KG) to remove dust, maintaining HVAC efficiency.

Lubrication Maintenance

Apply API-certified lubricating oil to moving parts such as ZJ30 turntable drive shafts, 648408201s bearings, and DQ70BSC clamp head assemblies regularly. Follow the equipment manual for lubricant type and quantity to reduce friction loss and extend part service life. Check clutch air bag assemblies (50D LT500/125) for air leakage and replace if damaged.

Storage & Handling

Store unused parts in a dry, ventilated, and clean warehouse, away from moisture, dust, and corrosive substances. Precision parts like QDT SYS-175 lithium batteries, Rexroth valves, and PDC drill bits should be kept in sealed packaging to avoid damage. When handling heavy parts (e.g., turntable drive shafts, clamp head assemblies), use appropriate tools to prevent collision and deformation. For explosion-proof grouting pumps, store in a cool, dry place to maintain explosion-proof performance.

Replacement Standards

Replace parts immediately if they show the following signs: excessive wear (e.g., PDC drill bits, dynamic friction discs), deformation (e.g., drive shafts, ram bodies), leakage (e.g., O-rings, oil seals), or failure to meet operational requirements (e.g., pressure gauges, brake valves).
