Function Description

Each product is engineered to fulfill the specific functional requirements of its matched equipment, ensuring efficient, safe, and stable operation. The core functions of key product categories are as follows, explained in simple, practical terms:

Drilling Rig & Brake Parts

Turntable drive shafts (ZJ50D, ZJ-30) and roller shafts (ZJ-30C) transmit power to drilling components, ensuring smooth operation of ZJ series drilling rigs. Turntable large square tiles (ZJ DBDS6K10/200 ZP275) provide support and stability for turntable rotation. Brake devices (ZJ50L KB-35, ZJ-70 TFX400*80, ZJ30C ZX30-160XL) ensure reliable braking during drilling operations, preventing accidents. ZJ-70 plunger pumps (A10VSO10DR/52R) deliver high-pressure hydraulic fluid, powering hydraulic components. Combination valves (ZJ-30 HC-2-LX/P55582-0003) regulate fluid flow, enabling precise control of drilling operations.

Crane & Winch Parts

ZJ70 anti-collision crane devices (31-113FB-III digital intelligence) prevent crane collisions, enhancing operational safety. Crane pressure plates (ZJ70 JJ745415-59) secure crane components, ensuring stable lifting. Winch drive shafts (ZJ70) transmit power to winches, enabling precise lifting of drilling tools. Water separators (ZJ70 QSL-25) remove moisture from compressed air, protecting pneumatic components from corrosion.

Transmission & Hydraulic Parts

Corner box drive shafts (5000700125) and gear couplings (ZJ50D CIICL12-150*162) transfer power between components, reducing vibration and ensuring stable transmission. Shuttle valves (ZJ-30C IA-341/4900350110) and two-position three-way reversing valves (23JR6-L8) control hydraulic fluid direction, enabling smooth switching of equipment working states. Lip seals (B090S01, B200 X 230 X 15) and DAM078HS1 seals provide reliable sealing, preventing fluid leakage in high-pressure environments. Throttle control valves (IA-414/AB-1) regulate fluid flow rate, ensuring precise control of hydraulic systems.

Filters & Electrical Parts

Diesel filters (901-202 MRP-2002) and oil suction filters (ZJ-70 TFX400*80, ZJ30C ZX30-160XL) remove impurities from fuel and oil, protecting engines and hydraulic systems from wear. Filter elements (FS1000, 1R0749, 6L4714) maintain filtration efficiency, extending component service life. FQN24-10ZK ten-pin aviation plugs (female) ensure stable electrical connections, while high-voltage electrical equipment (9907-018) and voltage regulators (DECS-100-B15) maintain stable power supply. Explosion-proof temperature transmitters (DQ70BS GW200A 3808000072) monitor equipment temperature, preventing overheating.

Drilling & Pump Parts

3112mm MS1952SS diamond drill bits drill through rock and soil, enabling oilfield exploration and drilling. FH6147 impellers and BOMCO dedicated pistons (F1300/1600CP160) drive pumps, ensuring stable fluid circulation. Crankshafts (W XW7Z-6D309-AA) and connecting rods (9Y7735) transfer power to pump pistons, maintaining pump performance. Weight table shock valve assemblies (JZ250 JY246.2.6) absorb shocks, ensuring accurate weight measurement during drilling.

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 roller shafts, ZJ50L brake device bearings (KB-35), ZJ70 anti-collision crane devices (31-113FB-III), and DQ70BS explosion-proof temperature transmitters (GW200A) 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 drive shafts and drill bits, wear-resistant rubber for seals and lip seals, and corrosion-resistant materials for electrical connectors. 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, filter elements (FS1000, 1R0749) and diesel filters (901-202 MRP-2002) adopt a snap-on design for quick replacement; FQN24-10ZK aviation plugs enable fast electrical connections. Even complex parts like ZJ70 anti-collision devices have intuitive installation marks, reducing installation time.

• Safety-Critical Design: Parts related to equipment safety—such as anti-collision crane devices, emergency brake valves (SH361-3517), and explosion-proof temperature transmitters—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 seals (B090S01, DAM078HS1), hoses, electrical connectors (FQN24-10ZK), and brake components daily. Ensure there is no looseness, leakage, or damage. For lip seals, oil seals, and retaining rings, check for aging or cracks—replace them immediately if issues are found to avoid fluid leakage and equipment damage. Inspect anti-collision crane devices (31-113FB-III) for proper operation.

Regular Cleaning & Replacement

Replace diesel filters (901-202 MRP-2002), filter elements (FS1000, 1R0749, 6L4714), and lubrication regulators (103321 6837881) every 25-30 days (or according to equipment operation hours) to maintain performance. Clean diamond drill bits (3112mm MS1952SS) and impellers (FH6147) to remove debris, preventing wear and ensuring drilling/pump efficiency. Clean electrical components to avoid contact failure.

Lubrication Maintenance

Apply API-certified lubricating oil to moving parts such as drive shafts (ZJ50D, ZJ-30), gear couplings (CIICL12-150*162), and crankshafts (W XW7Z-6D309-AA) regularly. Follow the equipment manual for lubricant type and quantity to reduce friction loss and extend part service life. Check return springs (KG-48) and lock springs (GB93-87) 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 GE-MWD pulse generator sieves (981477), voltage regulators (DECS-100-B15), and filter elements should be kept in sealed packaging to avoid damage. When handling heavy parts (e.g., turntable drive shafts), use appropriate tools to prevent collision and deformation.

Replacement Standards

Replace parts immediately if they show the following signs: excessive wear (e.g., friction plates 06835687 23042199, diamond drill bits), deformation (e.g., drive shafts), leakage (e.g., lip seals B090S01), or failure to meet operational requirements (e.g., anti-collision crane devices, temperature transmitters).
