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, ZJ70 5126000670 explosion-proof solenoid valves, ZJ45 winch intermediate shafts, TDS 4301000830 bearings, and Metso SA207007 expeller covers 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, bearings, and bolts, wear-resistant rubber for O-rings and seal rings, and corrosion-resistant materials for electrical connectors and pump components. This ensures resistance to wear, corrosion, high temperature, and high pressure, extending part service life.

• User-Friendly Design: We prioritize on-site operation convenience. For example, quick self-sealing connectors (00118) and quick release valves (SE-1/2-B) enable fast installation and disassembly; friction discs and sealing pads are easy to replace. Even complex parts like MWD inclinometer components have intuitive installation marks, reducing maintenance time.

• Safety-Critical Design: Parts related to equipment safety—such as ZJ70 explosion-proof solenoid valves, boiler pressure gauges, and one-way clutches—adopt multiple safety structures to prevent failure during high-load or emergency operations, protecting operators and equipment.

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 O-rings (414247060X), high-pressure hoses (JB1885-77), electrical connectors, and friction discs (W30-07-915) daily. Ensure there is no looseness, leakage, or damage. For seal rings, sealing pads, and exhaust pipe seals (9Y4582/1288452), check for aging or cracks—replace them immediately if issues are found to avoid fluid or air leakage and equipment damage. Inspect boiler pressure gauges and fuel gauges for accurate readings.

Regular Cleaning & Replacement

Clean 4445mm MS1951SS PDC drill bits regularly to remove debris, ensuring drilling efficiency. Replace friction discs (W30-07-915, W36-07-900.06) and sealing pads (AH100101210704) every 30-40 operation hours to maintain performance. Clean MWD inclinometer components (201921, 981513) to prevent dust buildup and ensure accurate measurement.

Lubrication Maintenance

Apply API-certified lubricating oil to moving parts such as 32622H bearings (4500100127), TDS 4301000830 bearings, and ZJ-40 ventilated clutch springs (LT1168*305T) regularly. Follow the equipment manual for lubricant type and quantity to reduce friction loss and extend part service life. Check tension springs (BK-12-7A) 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 MWD inclinometer mushroom heads (981213), multi-turn potentiometers (JML3296), and bearings should be kept in sealed packaging to avoid damage. When handling heavy parts (e.g., winch intermediate shafts, hook assemblies), use appropriate tools to prevent collision and deformation.

Replacement Standards

Replace parts immediately if they show the following signs: excessive wear (e.g., friction discs, PDC drill bits), deformation (e.g., guide rings P1100160AA), leakage (e.g., O-rings), or failure to meet operational requirements (e.g., explosion-proof solenoid valves, boiler contactors).
