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:
• Regular Inspection: Check hydraulic components (e.g., Hydraulic Motor 151B3005, Parking Valve DG17V-3-2N-6) and sealing parts (e.g., Skeleton Oil Seal AH1301010311) every 80 operating hours; replace worn or damaged parts in time to avoid system failure.
• Cleaning & Lubrication: Keep PDC drill bits, sprocket wheels (JC21A-01-06), and bearings clean; apply appropriate lubricating oil (matching the equipment manual) to reduce friction and prevent rust and wear.
• Storage Requirements: Store parts in a dry, ventilated, and dust-free warehouse; avoid direct sunlight and contact with corrosive substances (especially electrical components and sealing parts). For explosion-proof parts, store them in a cool, moisture-free environment to maintain their explosion-proof performance.
• Installation Notes: Ensure parts are installed correctly according to the equipment manual; avoid forced installation (e.g., aligning ZJ-70DB Drum Shaft Nut M16-F4-11-93 properly to prevent thread damage). For electrical components, ensure correct wiring to avoid short circuits.
• Filter & Fluid Maintenance: Regularly replace water filters (BW5140) and hydraulic oil filters to ensure the cleanliness of fluids; use high-quality antifreeze (5402650056) in boilers and cooling systems to prevent freezing and corrosion.

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: PDC Drill Bit Wear in ZJ70 Drilling Rig
A customer’s ZJ70 drilling rig used a non-original PDC drill bit, which wore out after only 40 hours of drilling in hard formations, leading to unplanned downtime and increased drilling costs. We supplied our PDC Drill Bit 2159mm ST636RS, which features high-hardness diamond cutters and a wear-resistant body. After replacement, the bit operated stably for 130 hours, reducing downtime by 70% and lowering drilling costs per meter.
Case 2: Hydraulic Motor Failure in TDS Pipe Handler
An oilfield’s TDS pipe handler experienced frequent jams due to a faulty hydraulic motor (non-original), affecting drilling efficiency. We provided the Hydraulic Motor Pipe Handler Rotation 151B3005 (Part Number: 5126000790), which is fully compatible with OMT-500 pipe handlers. After installation, the pipe handler operated smoothly, eliminating jams and improving pipe handling efficiency by 40%.
Case 3: Oil Leakage in ZJ40L Drilling Rig Winch
A ZJ40L drilling rig’s winch had serious oil leakage due to a worn skeleton oil seal. We supplied the Skeleton Oil Seal AH1301010311, which features a double-lip design for tight sealing. After replacement, the oil leakage problem was completely solved, and the winch operated continuously for 500 hours without further issues, reducing maintenance costs and downtime.
