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, ZJ30C P2200677AA brake screws, DQ70BSD 4301000460 top drive bearings, WNS1.0-1.25-Y PN2.5 DN40 cut-off valves, and LHE3012B inclinometer 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, gears, and valves, wear-resistant alloy for brake pads and friction wheels, heat-resistant materials for boiler components and engine parts, and oil-resistant rubber for sealing rings. This ensures resistance to wear, corrosion, high temperature, and high pressure (up to 70MPa for high-pressure gate valves), extending part service life.

• User-Friendly Design: We prioritize on-site operation convenience. For example, H3 quick connectors and straight connectors enable fast installation and disassembly; filter elements and sealing rings are easy to replace. Even complex parts like repair kits and combination valves have standardized components, reducing maintenance time and labor intensity.

• Safety-Critical Design: Parts related to equipment safety—such as ZJ70 brake pads, 4900300056 copper safety valves, rear axle brake chambers, and main drum combination valves—adopt multiple safety structures to prevent failure during high-load or emergency operations, protecting operators and equipment. High-pressure valves meet strict pressure standards to ensure safe operation in high-pressure scenarios.

Our products are built to adapt to the harshest industrial and oilfield environments, ensuring stable performance in diverse scenarios. The main applicable working conditions are as follows:

Oilfield Drilling & Winch Scenarios

Suitable for onshore and offshore drilling operations (desert, plateau, coastal) with ZJ30C, ZJ45, ZJ50D, ZJ70DB drilling rigs. Products such as 26″ P1 steel tooth roller bits, ZJ30C brake system screws, and ZJ70DB winch filter elements can withstand high temperature, high humidity, dust, vibration, and high pressure, ensuring continuous drilling and winch operation.

Hydraulic & Top Drive Scenarios

For DQ70BS, DQ70BSD hydraulic systems and top drives. Hydraulic valves, special bearings, and assembly hoses adapt to high-pressure fluid and high-vibration environments, ensuring stable hydraulic system and top drive operation.

Boiler & Industrial Scenarios

For WNS1.0-1.25-Y, 10T/GY10-125 boilers and industrial equipment. Boiler cut-off valves, induced draft fan assemblies, and safety valves adapt to high-temperature industrial environments, ensuring safe and efficient boiler operation and stable industrial equipment performance.

Inclinometer & Transmission Scenarios

For LHE-3201 MWD inclinometers and drilling transmission systems. Inclinometer data processors, tachometers, and ring gears adapt to harsh field conditions and high-load transmission scenarios, ensuring accurate inclinometer measurement and reliable power transmission.

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 530301190160024000 O-rings, ZJ70DB SPX-06*25 filter elements, ZJ30C brake screws, and boiler cut-off valves daily. Ensure there is no looseness, leakage, or damage. For air filters, filter elements, and felt rings, check for clogging or wear—replace them immediately if issues are found to avoid component damage. Inspect safety valves and brake pads for proper operation.

Regular Cleaning & Replacement

Replace filter elements (1R0756, 3827643, SPX-06*25) every 25-30 operation hours to maintain fluid cleanliness. Clean 26″ P1 steel tooth roller bits regularly to remove debris, ensuring drilling efficiency. Replace brake pads (ZJ70 BQ-22) and sealing rings (ZJ70D D4-4-66) if signs of wear are present, ensuring brake system and hydraulic system performance. Clean boiler induced draft fan assemblies to remove dust and debris, maintaining boiler efficiency.

Lubrication Maintenance

Apply API-certified lubricating oil to moving parts such as DQ70BSD top drive special bearings, ZJ45 turntable friction wheels, and input shafts (E900-11000133) regularly. Follow the equipment manual for lubricant type and quantity to reduce friction loss and extend part service life. Check connecting rod bolts (0947154) and nuts (0947516) for tightness 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 LHE3012B inclinometer data processors, high-pressure valves, and drill bits should be kept in sealed packaging to avoid damage. When handling heavy parts (e.g., large ring gears, induced draft fan assemblies), use appropriate tools to prevent collision and deformation. For repair kits, store in a dry place to maintain component integrity.

Replacement Standards

Replace parts immediately if they show the following signs: excessive wear (e.g., brake pads, steel tooth roller bits), deformation (e.g., connecting rods, input shafts), leakage (e.g., O-rings, gaskets), or failure to meet operational requirements (e.g., safety valves, filter elements).
