Structural Features

Design Advantages

All products adopt industry-proven structural designs, combining durability, compatibility, and ease of maintenance—engineered to withstand the harsh conditions of oilfield operations while meeting the highest quality standards:

• High-Strength Material Selection: Mechanical parts (clamp assemblies, pump shafts, gears) are made of 40Cr alloy steel,经过 quenching and tempering treatment to achieve a hardness of HRC 35-40, ensuring wear resistance and load-bearing capacity. Fasteners are made of 12.9 grade high-strength steel, with a tensile strength of 1220MPa.

• Precision Machining: Hydraulic valves, connectors, and pump shafts are manufactured using CNC precision machining, with dimensional accuracy of ±0.02mm, ensuring perfect compatibility with original ZJ series drilling rig parts. This reduces assembly time by 25% and eliminates fitment issues.

• Sealing & Corrosion Resistance: Gaskets (6V3907, 8E-8307) and oil rings (6T0252) use nitrile rubber and fluorine rubber materials, with high temperature resistance (up to 150°C) and oil resistance, ensuring a sealing life of 6-12 months. All metal parts undergo zinc plating or galvanizing treatment, passing 72-hour salt spray tests with no corrosion.

• Explosion-Proof & Safety Design: Explosion-proof solenoid coils (ZJ70D 230VAC 512705040600123) and electrical components meet Ex d IIB T4 explosion-proof standards, suitable for flammable and explosive oilfield environments. Vibration motors (VLB-30154-WA) have IP65 protection rating, preventing dust and water ingress.

• Maintenance-Friendly Design: Quick connectors (ZJ50L H8-62) enable tool-free installation and disassembly, reducing maintenance time by 40%. Repair kits (MRP-1034S-OB) include all necessary components for on-site repairs, eliminating the need for multiple part purchases.

• High-Temperature & High-Pressure (HTHP) Environments: Hydraulic components, gaskets, and MWD cartridges can operate stably at temperatures up to 150°C and pressures up to 150MPa, meeting the requirements of HTHP well operations (API 11D1 standard).

• Corrosive & High-Humidity Scenarios: Anti-corrosion treated parts (fasteners, connectors) resist corrosion from drilling fluid, seawater, and saline-alkali, with a service life 30% longer than ordinary parts in offshore and coastal oilfields.

• Heavy-Load & High-Vibration Operations: Mechanical parts (winch shafts, gears, clamp assemblies) withstand continuous heavy loads (up to 500kN) and strong vibration (≤15g), ensuring stable operation during drilling and lifting.

• Flammable & Explosive Environments: Explosion-proof electrical parts meet Ex d IIB T4 standards, ensuring safe operation in oilfield environments with flammable gases (methane, propane) and dust.

Maintenance & Care Suggestions

Proper maintenance and care are critical to extending the service life of oilfield equipment parts, reducing failure rates, and optimizing operational efficiency. Below are practical, on-site-friendly maintenance recommendations based on industry best practices:

• Regular Inspection: Conduct weekly visual checks of key parts (clamp assemblies, hydraulic valves, brake blocks) to detect wear, deformation, or leakage. For MWD cartridges (201012) and pressure transmitters (QBY-32), test performance monthly to ensure accuracy (±0.1° for inclinometers, ±0.5% FS for transmitters).

• Fastener Maintenance: Check hex head bolts (M12×30, M14×72) every 15 days for loose connections; torque to 80-100N·m (for M12) and 120-150N·m (for M14) to ensure stability. Replace bolts with signs of corrosion or fatigue.

• Hydraulic & Sealing Maintenance: Replace oil filter (51.05504-0098) every 3 months or after 500 operating hours. Inspect hydraulic hoses (414247057M) for cracks or aging; replace if the outer layer is damaged. Apply lubricating grease (lithium-based, NLGI 2) to valves and connectors every 20 days.

• Brake & Clutch Maintenance: Check JC-400B disc brake blocks for wear; replace when thickness is less than 8mm. Inspect clutch springs (LT700*135DY) for deformation; replace if the spring force is reduced by more than 10%.

• Electrical Part Maintenance: Keep explosion-proof solenoid coils and vibration motors clean and dry. Calibrate pressure transmitters (QBY-32) quarterly to ensure accuracy. Replace generator belts (3S6272/6530) every 6 months or if signs of cracking appear.

On-Site Fault Maintenance Cases

The following 3 real on-site fault cases provide practical guidance for solving common oilfield equipment problems, helping maintenance teams quickly diagnose and resolve issues, and minimizing downtime (average resolution time ≤2 hours):

Case 1: ZJ50L Drilling Rig Hydraulic System Pressure Loss

Fault Phenomenon: A ZJ50L drilling rig’s hydraulic system experiences sudden pressure loss (from 80MPa to 40MPa), leading to slow winch operation. Inspection shows the Pilot Multiple Check Valve for TDS (P/N 5126000320) is clogged with debris, causing restricted oil flow.

Solution: Disassemble the check valve, clean the internal valve core and passage, and reinstall it. If clogging is severe, replace the valve with a new 5126000320 model. After maintenance, the hydraulic pressure returns to 80MPa, and the winch operates normally—resolving the issue in 1.5 hours.

Case 2: MWD Inclinometer Measurement Inaccuracy

Fault Phenomenon: An MWD system on a ZJ45 drilling rig shows inaccurate well path measurements (inclination error >0.5°), affecting drilling accuracy. Inspection confirms the MWD Inclinometer Compass Cartridge 201012 is contaminated with drilling fluid, leading to signal interference.

Solution: Replace the contaminated cartridge with a new 201012 model, ensure proper sealing of the MWD housing, and flush the signal line. After replacement, the inclinometer accuracy is restored to ±0.1°, and drilling proceeds without deviation—resolving the issue in 2 hours.

Case 3: ZJ70D Drilling Rig Brake Failure

Fault Phenomenon: A ZJ70D drilling rig’s disc brake fails to provide sufficient braking force during lifting, posing safety risks. Inspection reveals the JC-400B Disc Brake Blocks are worn (thickness <7mm) and the Clutch Spring LT700*135DY is deformed.

Solution: Replace the worn brake blocks with new JC-400B models and the deformed spring with a new LT700*135DY. Adjust the brake clearance to 0.5-1mm and test the braking force (≥120kN). After maintenance, the brake operates stably—resolving the issue in 1.8 hours.
