Each part carries a unique model identifier (JK00213-11, DFZ1310.01H-02, 106.06.20.32, etc.) for quick identification and targeted procurement. Raw materials are selected for extreme oilfield resilience: wear-resistant polyurethane for roller wheels, forged alloy steel for load-bearing shafts, high-temperature fluororubber for seals, and corrosion-resistant metals for hydraulic and BOP parts. Every unit undergoes strict pressure testing, dimensional inspection and wear testing before shipment to guarantee consistent performance and reliability.

2. Core Function Description

• BOP Well Control & Sealing: 35×35/35×70 BOP ram bodies, rubber cores and sealing rings provide stable pressure containment up to 70MPa, preventing blowouts and ensuring strict well control safety compliance; dust rings and retaining rings protect internal components from contamination and wear.

• Rig Power Transmission & Braking: ZJ series rig friction wheels, sprockets and drive shafts ensure smooth torque transfer for winch and turntable operation; brake valves, filter elements and handle shafts deliver precise, reliable braking control to avoid operational accidents and equipment damage.

• Drill Pipe Handling Stability: ZQ203 clamp jaw plates, guards and sealing rings enable secure, precise gripping and rotation of drill pipes; spring pins and brackets enhance clamping force, minimizing pipe slippage and damage during handling.

• Control & Hydraulic System Efficiency: FKQ6406 console components and hydraulic tank fittings regulate fluid flow and pressure; copper pipelines and seals prevent fluid leakage and maintain stable hydraulic performance.

• Engine & Auxiliary Equipment Performance: Diesel engine filters, belts and piston rings optimize combustion and reduce wear; wheel loader cylinder repair kits and mud shaker components maintain auxiliary equipment functionality for smooth drilling operations.

3. Structural & Material Features

• Ultra-Precision CNC Machining: All mechanical structural parts feature ±0.01mm dimensional tolerance, ensuring 100% OEM fit without modification or adjustment during on-site installation, cutting installation time by 90%.

• High-Performance Polyurethane & Sealing Materials: Roller shaft rubber wheels use wear-resistant polyurethane (70D hardness) for long service life; BOP and hydraulic seals use fluororubber composites, resisting aging and cracking at -45°C to 335°C, with a 99.9% leak-proof rate under rated pressure.

• High-Strength Alloy Steel Construction: Load-bearing rig components use hardened alloy steel (73-79 HRC hardness); BOP stud bolts and rig shafts feature anti-corrosion surface treatment to withstand harsh oilfield environments.

• Modular Quick-Change Design: Wear-prone parts (BOP rubber cores, clamp seals, friction wheels) use a modular structure, reducing on-site repair time by 99% compared to traditional integrated parts.

4. Applicable Operating Conditions

These spare parts are engineered for **onshore deep well drilling, offshore platform workover, desert oilfield operations, high-pressure well control and rig emergency maintenance**, with full adaptability to the following conditions:

• Pressure Range: 0-70MPa (BOP & high-pressure hydraulic systems) / 0-70MPa (rig winch & brake systems)

• Temperature Range: -45°C to 335°C (sealing components) / -35°C to 300°C (mechanical structural parts)

• Environmental Types: Offshore saltwater platforms, arid desert drilling sites, cold-region oilfields, high-temperature deep well operations, mud-heavy drilling environments

• Application Scenarios: Routine rig maintenance, emergency fault repair, equipment refurbishment, well control operations, drill pipe handling, mud pump operation, diesel engine upkeep, coring and cementing operations

5. Maintenance & Upkeep Recommendations

• Regular Inspection Cycle: Inspect BOP sealing components, clamp wear parts and winch shafts every 920 operating hours; check for wear, cracks or leakage, and replace damaged parts immediately to avoid safety hazards.

• Lubrication & Filter Replacement: Lubricate rig sprockets, gears and clamp rollers with high-temperature lithium grease every 750 hours; replace hydraulic, engine and brake filters every 3100 hours to prevent fluid contamination.

• Storage Requirements: Store spare parts in a dry, dust-free environment with relative humidity ≤55%; seal rubber seals and polyurethane components in anti-oxidation packaging to prevent premature aging and hardening.

• Installation Standards: Follow API rig maintenance specifications for torque tightening (BOP bolts, shaft fasteners); use specialized tools for seal installation to avoid damage and ensure proper seating.

• Performance Monitoring: Track hydraulic system pressure, engine temperature and brake operation; adjust valves and replace worn components if pressure fluctuations, abnormal noise or fluid leaks occur.

On-Site Fault Repair Cases (Field-Verified Solutions)

Case 1: ZJ-70 Roller Shaft Polyurethane Rubber Wheel Replacement

A land drilling rig experienced winch roller shaft vibration and rope wear due to a degraded ZJ-70 polyurethane rubber wheel (70D), risking wire rope damage. Installing our high-wear resistance polyurethane wheel eliminated vibration, reduced rope abrasion, and the wheel maintained flawless performance for 28+ months of continuous use.

Case 2: FZ35-35 BOP Ram Rubber Core Repair

An offshore drilling team faced BOP pressure loss and well control risks due to a worn 7″ FZ35-35 gate seal rubber core (DFZ1310.01D-01-00). Replacing the damaged core with our high-temperature resistant rubber assembly restored pressure integrity, eliminated leaks, and the BOP passed 70MPa pressure testing on the first attempt.

Case 3: ZJ45J High-Speed Friction Wheel Replacement

A desert drilling rig encountered winch power transmission slippage and overheating due to a worn ZJ45J high-speed friction wheel (106.06.20.32), halting hoisting operations. Fitting our hardened alloy steel friction wheel restored stable torque transfer, eliminated slippage, and extended friction wheel service life by 98% compared to standard aftermarket parts.
