Structural Features

Our products are designed with a focus on compatibility, durability, and ease of use—directly addressing the common challenges users face with generic parts, such as poor fit, short service life, and difficult installation. Key structural features include:

• 1:1 OEM Compatibility: Every part is manufactured to the exact specifications of the original equipment. For example, ZJ70DB LT07MKA-2X/080/02M brake valves, DQ70BS DL0301065J control cable assemblies, TDS 5126000330 flow restrictor valves, and YST-48R 0202008 ground data processors match the original equipment perfectly, allowing direct replacement without modifying the equipment structure or using special tools.

• High-Durability Materials: Key parts use industry-grade materials to withstand harsh conditions—high-strength steel for drill bits, drive shafts, and valves, wear-resistant alloy for clutch components and friction cores, heat-resistant materials for explosion-proof electric heaters and engine parts, and oil-resistant rubber for sealing rings. This ensures resistance to wear, corrosion, high temperature, and high pressure (up to 10000psi for choke manifold valves), extending part service life.

• User-Friendly Design: We prioritize on-site operation convenience. For example, ZJ70 3/8BSP quick connectors and H2-62 quick couplers enable fast installation and disassembly; filter elements and sealing rings are easy to replace. Even complex parts like control circuit boards and inclinometer ground data processors have standardized mounting points, reducing maintenance time.

• Safety-Critical Design: Parts related to equipment safety—such as BGY2-220/1 explosion-proof electric heaters, RRV3-7500U spring return safety valves, ZJ50 safety gears, and brake cylinders—adopt multiple safety structures to prevent failure during high-load or emergency operations, protecting operators and equipment. Explosion-proof design ensures safe operation in hazardous oilfield environments.

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 5300100121 O-rings, DQ70BS control cable assemblies, ZJ70DB brake valves, and electrical connectors daily. Ensure there is no looseness, leakage, or damage. For oil filters (36001-06A3300), filter elements (4N0015), and oil suction filters (TF-63), check for clogging or wear—replace them immediately if issues are found to avoid component damage. Inspect safety valves (RRV3-7500U) and brake cylinders for proper operation.

Regular Cleaning & Replacement

Replace filter elements (4N0015) and oil filters (36001-06A3300) every 25-30 operation hours to maintain fluid cleanliness. Clean 2159mm M1665SS PDC drill bits regularly to remove debris, ensuring drilling efficiency. Replace piston rings (1979299) and sealing rings (C2 F015 N3584) if signs of wear are present, ensuring hydraulic system and engine performance. Clean TDS flow restrictor valves (5126000330) to prevent clogging.

Lubrication Maintenance

Apply API-certified lubricating oil to moving parts such as denison M4SD-088-3N00-B502 vane motors, ZJ30C turntable drive shafts, and MR5000 clutch sliding sleeves regularly. Follow the equipment manual for lubricant type and quantity to reduce friction loss and extend part service life. Check free wheel shrapnels (23018535) for elasticity and replace if worn.

Storage & Handling

Store unused parts in a dry, ventilated, and clean warehouse, away from moisture, dust, and corrosive substances. Precision parts like YST-48R 0202008 ground data processors, CFB trigger control circuit boards, and PDC drill bits should be kept in sealed packaging to avoid damage. When handling heavy parts (e.g., turntable drive shafts, brake cylinders), use appropriate tools to prevent collision and deformation. For nitrogen filling tools (FPU-1-250F250F25G11A3K), store in a cool, dry place to maintain performance.

Replacement Standards

Replace parts immediately if they show the following signs: excessive wear (e.g., PDC drill bits, dynamic friction cores 510745), deformation (e.g., pulley shafts P2400454AA), leakage (e.g., O-rings), or failure to meet operational requirements (e.g., safety valves, control circuit boards).
