Drilling Rig & Winch Parts

ZJ-50 winch intermediate shafts transmit power to winch systems, enabling smooth lifting of drilling tools. ZJ30C brake device six valves (W6P) control brake hydraulic flow, ensuring reliable braking of ZJ30C drilling rigs. ZJ70D-ZJ30DBS-ZJ50D air valves (23Q-L15-K QY23) regulate air flow, supporting drilling rig operation. ZJ-50 JQHSB 50×12 silencers reduce noise from drilling rig components, improving on-site working conditions. ZJ15DB quick connectors (NPT3/4″) enable fast and secure connection of fluid lines.

Hydraulic & Hose Parts

DQ70BSC 97052240 and DQ70BSD 9715222012 hose assemblies transmit high-pressure hydraulic fluid, ensuring stable operation of DQ70BSC/DQ70BSD hydraulic systems. DQ70 spindle adjustment pads (0.25mm) adjust spindle position, ensuring precise hydraulic control. DQ70 SPIDEX couplings (A28-3B) connect rotating components, transmitting power smoothly. Lift cylinders (Z07120000001AA) lift drilling rig components, while quick connectors (Z07270000010AA) enable fast disconnection and connection of hydraulic lines.

Engine & Oil Pump Parts

C9 engine 7M4718 fan belts and 8N6717/8930 fan belts drive engine cooling fans, preventing engine overheating. Engine repair kits (6V2900/1383069) provide all necessary parts for C9 engine maintenance, simplifying repair work. Piston rings (288646) seal engine cylinders, ensuring engine efficiency. DRS & WBZ-63 oil pump assemblies supply lubricating oil to equipment, reducing friction and extending component service life.

Mud Pump & Inclinometer Parts

F-800 mud pump fixed cards (AH1001010521) secure mud pump components, maintaining pump stability. 43056 impellers drive mud flow, ensuring efficient mud circulation. YST-48R MWD inclinometer wear-resistant sleeves (4803116) protect inclinometer sensors, ensuring accurate measurement. Oil pressure gauges (29505797, 7W2937) and pressure gauges (3800200010) monitor equipment operating parameters, preventing overpressure and component damage.

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, DQ70BSC 97052240 hose assemblies, ZJ30C W6P brake valves, C9 engine 7M4718 fan belts, and YST-48R 4803116 inclinometer sleeves 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 flanges, bearings, and bolts, wear-resistant rubber for O-rings and gaskets, and heat-resistant materials for engine components and brake drums. 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 connectors (Z07270000010AA) and hose assemblies enable fast installation and disassembly; friction discs (W36-07-900) and brake drums (E790-04010002) are easy to replace. Even complex parts like manual pressure regulators (TR8-L6-D) have intuitive adjustment controls, reducing maintenance time.

• Safety-Critical Design: Parts related to equipment safety—such as ZJ30C brake valves, check valves (512704100000064000), and pressure gauges—adopt multiple safety structures to prevent failure during high-load or emergency operations, protecting operators and equipment.

Applicable Working Conditions

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

Products such as ZJ-50 winch intermediate shafts, ZJ30C brake valves, and DQ70BSD hose assemblies can withstand high temperature, high humidity, dust, vibration, and high pressure, ensuring continuous drilling and winch operation.

Hydraulic & Engine Scenarios

For DQ70BSC/DQ70BSD hydraulic systems and C9 engines (CLJ11969). Hydraulic hoses, couplings, and engine parts adapt to high-temperature, high-pressure, and high-vibration environments, ensuring stable engine and hydraulic system operation.

Mud Pump & Inclinometer Scenarios

For F-800 mud pump sets and YST-48R MWD inclinometers. Mud pump parts and inclinometer sleeves adapt to abrasive mud and harsh field conditions, ensuring reliable mud pump operation and accurate inclinometer measurement.

Industrial & General Scenarios

Suitable for industrial equipment, including oil pumps, transmission systems, and instruments. Bearings, filters, and electrical parts adapt to industrial workshop and field environments, ensuring stable equipment operation.

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 (20X2.65 5300100059), DQ70BSC/DQ70BSD hose assemblies, brake drums (E790-04010002), and electrical connectors daily. Ensure there is no looseness, leakage, or damage. For gaskets, felt rings (B046G01), and flushing pipe packings (SL225), check for aging or cracks—replace them immediately if issues are found to avoid fluid leakage and equipment damage. Inspect pressure gauges and oil pressure gauges for accurate readings.

Regular Cleaning & Replacement

Replace transmission filters (P-166254/PT317-MPG) and suction filters (LXZ-400X80F-S) every 25-30 operation hours to maintain fluid cleanliness. Clean 43056 impellers and mud pump components regularly to remove debris, preventing blockages. Replace fan belts (7M4718, 8N6717/8930) and friction discs (W36-07-900) if signs of wear are present, ensuring engine and brake performance.

Lubrication Maintenance

Apply API-certified lubricating oil to moving parts such as 430129150464777000 bearings, spherical roller bearings (430103002231000026), and plungers (2W3413) regularly. Follow the equipment manual for lubricant type and quantity to reduce friction loss and extend part service life. Check DRS & WBZ-63 oil pump assemblies for proper operation and refuel as needed.

Storage & Handling

Store unused parts in a dry, ventilated, and clean warehouse, away from moisture, dust, and corrosive substances. Precision parts like YST-48R MWD inclinometer sleeves (4803116), current transformers (CJH-0.66), and bearings should be kept in sealed packaging to avoid damage. When handling heavy parts (e.g., winch intermediate shafts, brake drums), 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, fan belts), deformation (e.g., flanges P8000179AA), leakage (e.g., O-rings), or failure to meet operational requirements (e.g., brake valves, pressure gauges).
