Maintenance & Care Suggestions

Proper maintenance is key to extending the service life of mechanical parts and reducing replacement costs. Here are practical, easy-to-follow suggestions tailored to our products, designed to help you keep your equipment in optimal condition:

• Regular Inspection: Check ZJ20 turntable drive shafts, ZJ70D mechanical gate valves, and CAT3408 oil pumps every 65 operating hours; inspect sealing parts (O-RING 17X265G) and bearings (Self-Lubricating Bearing 430117010041320000) for wear, leakage, or damage, and replace them in time to avoid system failure.

• Cleaning & Lubrication: Keep drive shafts, oil pumps (CAT3408), and self-lubricating bearings clean; apply appropriate lubricating oil to non-self-lubricating bearings and transmission components to reduce friction and prevent rust and wear. For filters, clean or replace filter elements regularly to maintain filtration efficiency.

• Storage Requirements: Store parts in a dry, ventilated, and dust-free warehouse; avoid direct sunlight and contact with corrosive substances (especially electrical components, seals, and engine parts). For high-pressure hoses, valves, and electrical parts, store them in a cool, moisture-free environment to maintain their performance.

• Installation Notes: Ensure parts are installed correctly according to the equipment manual; avoid forced installation (e.g., aligning bolts 420201061118035050 properly to prevent damage). For ZJ series drilling rig parts, CAT engine parts, and hydraulic components, follow OEM installation guidelines to ensure compatibility and safety.

• Electrical & Instrumentation Maintenance: Regularly check electromagnetic relays (LY2NJ DC24V) and limit switches (330203010039000000) for proper operation; inspect potentiometers and connectors for loose connections; clean electrical components to prevent dust accumulation and short circuits.

On-Site Fault Maintenance Cases

Here are 3 real on-site maintenance cases, showing how our parts solve practical problems for customers, reduce downtime, and improve equipment performance:

Case 1: Turntable Drive Shaft Wear in ZJ20 Drilling Rig

A customer’s ZJ20 drilling rig experienced turntable rotation instability and abnormal noise due to wear on the turntable drive shaft and intermediate drive shaft (L=1690 2211FF). We supplied the ZJ20 Turntable Drive Shaft & Intermediate Drive Shaft, which are fully compatible with the rig. After replacement and alignment, the turntable operated smoothly, power transmission was stable, and the rig resumed drilling operations, reducing downtime by 85%.

Case 2: Oil Pump Failure in CAT3408 Engine

A maintenance team encountered engine overheating and component wear due to a faulty CAT3408 oil pump, which failed to supply sufficient lubricating oil. We provided the CAT3408 Oil Pump, which is a direct OEM replacement. After installation and oil system flushing, the engine lubrication system operated normally, overheating was resolved, and engine service life was extended, with maintenance costs reduced by 70% compared to repairing the old pump.

Case 3: Mechanical Gate Valve Leakage in ZJ70D Drilling Rig

A drilling team’s ZJ70D drilling rig had drilling fluid leakage from a worn mechanical gate valve (4 1/16” x 15M PFF103-105), causing operational delays and fluid waste. We supplied the ZJ70D Mechanical Gate Valve, which fits perfectly with the rig’s pipeline system. After replacement and pressure testing, the leakage was completely resolved, the drilling fluid system operated stably, and drilling efficiency was fully restored.
