Maintenance & Care Suggestions

Proper maintenance is key to extending the service life of mechanical parts and reducing replacement costs, following the "daily inspection, weekly maintenance" routine adopted by professional drilling teams to prevent small issues from escalating into major faults. Here are practical, easy-to-follow suggestions tailored to our products, aligned with the "four-understand, three-can" equipment operation requirements and ten-point maintenance method:

• Regular Inspection: Follow a daily inspection routine to check Submersible Slurry Pump 400TJQ2000-35-315 components, ZJ70D manual reversing valves (4WMM 16G50/F), and high-pressure gate valves (DEMCO/DRILLMAX 2″) every 65 operating hours; use the "look, listen, smell, check" four-step diagnosis method to identify abnormalities early. Replace worn or damaged parts (such as seals 8M8515 and air filters 6I2503) in time to avoid leaks or system failure.

• Cleaning & Lubrication: Keep slurry pump shafts (BSC073M), bearings (4301000470 32240J2), and sprockets (E790-04000053) clean; apply appropriate lubricating oil (matching the equipment manual) to reduce friction and prevent rust and wear—following the ten-point maintenance method’s "clean and lubricate" requirements.

• 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 slurry pump parts, store them in a cool, moisture-free environment to maintain their performance—critical for preserving part integrity during storage.

• Installation Notes: Ensure parts are installed correctly according to the equipment manual or "equipment guide" materials similar to those used by drilling teams; avoid forced installation (e.g., aligning bolts 000197*0913 properly to prevent thread damage). For drilling rig components and slurry pumps, follow OEM installation guidelines to ensure compatibility and safety.

• Filter & Pump Maintenance: Regularly replace air filters (6I2503, 45 910 591 04) and filter elements (ZJ40 TZX2-250×30); clean slurry pump impellers (TG14148) and casings (SP65092) to prevent clogging; check electrical meters (0-2000 three-phase reactive power meter) regularly to ensure accurate readings and safe 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—mirroring the real-world challenges faced by drilling teams and resolved through prompt part replacement and professional maintenance:

Case 1: Slurry Pump Failure in Oilfield Mud Transportation

A customer’s Submersible Slurry Pump 400TJQ2000-35-315 experienced reduced flow rate and abnormal noise due to a worn impeller (TG14148), disrupting drilling mud discharge. We supplied the TG14148 Impeller, which is fully compatible with the 400TJQ2000-35-315 pump. After replacement, the pump resumed normal flow rate, and the mud transportation system operated stably for 750 hours, reducing downtime by 85% and ensuring uninterrupted drilling operations.

Case 2: Hydraulic Valve Malfunction in ZJ70D Drilling Rig

An oilfield’s ZJ70D drilling rig had unstable hydraulic system operation due to a faulty manual reversing valve, causing winch and hydraulic tong malfunctions. We provided the ZJ70D Manual Reversing Valve 4WMM 16G50/F, which is perfectly matched to the rig’s hydraulic system. After installation, the hydraulic system stabilized, and all components operated smoothly, preventing potential drilling delays and reducing maintenance costs by 40%.

Case 3: Gate Valve Leak in DEMCO Well Control System

A well control operation had fluid leakage from a DEMCO 2″ gate valve (5000 PSI) due to worn internal trim, risking well control safety. We supplied the DEMCO 2″ Gate Valve (P/N 203102522110), which meets API 16C standards. After replacement, the leakage was completely eliminated, and the well control system operated safely for 900 hours, ensuring compliance with safety regulations and avoiding costly incidents.
