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 Top Drive DQ250Z seal assemblies (1300132617), ZJ70D turntable sleeve bushings (ZP375), and high-pressure gate valves (Z23X-35) every 75 operating hours; replace worn or damaged parts (such as filter elements 1R0716 and seals DH078HS1) in time to avoid leaks or system failure.

• Cleaning & Lubrication: Keep roller bits (HJ527G, HJT537G), winch oil pump drive shafts (ZJ-20), and bushings (ZP375) 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, seals, and filters). For high-pressure valves and top drive 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 T502-6008K properly to prevent thread damage). For top drive parts and drilling rig components, follow OEM installation guidelines to ensure compatibility and safety.

• Filter & Boiler Maintenance: Regularly replace air filters (PA2444) and oil filter elements (1R0716, 1R0714); check boiler solenoid valves (121K6220) and thermal overload protectors (RL2 D13) regularly to ensure safe boiler operation.

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: Top Drive Leak in DQ250Z System

A customer’s DQ250Z top drive experienced fluid leakage due to a worn seal assembly, disrupting drilling operations and risking component damage. We supplied the Top Drive DQ250Z Seal Assembly 1300132617, which is fully compatible with the DQ250Z top drive. After replacement, the leakage was completely resolved, and the top drive operated stably for 600 hours, reducing downtime by 85%.

Case 2: Roller Bit Wear in Oilfield Drilling

An oilfield’s drilling operation had reduced drilling efficiency due to a worn non-original roller bit, leading to slower penetration rates. We provided the 8-1/2″ HJ527G Inserted Carbide Roller Bit, which is designed for harsh rock formations. After replacement, the drilling penetration rate improved by 45%, reducing drilling time and increasing productivity.

Case 3: Hydraulic Control Valve Failure in ZJ70DB Drilling Rig

A ZJ70DB drilling rig’s hydraulic system had unstable pressure due to a faulty hydraulic control valve, causing winch operation issues. We supplied the ZJ70DB Hydraulic Control Valve BK-F-3Y, which is perfectly matched to the rig’s hydraulic system. After installation, the hydraulic pressure stabilized, and the winch operated smoothly, ensuring uninterrupted drilling work.
