Detailed Product Description & Technical Parameters
1. Product Introduction
This comprehensive spare parts collection covers **ZJ series rig drive shafts, clutch hubs, sprockets and brake valves, 35×35/35×70 BOP gates, control assemblies, sealing rings and pistons, ZQ203-100/ZQ203-125 clamp jaw plates, flanges and connectors, FKDQ640/FKQ640 control box pressure transmitters, switches and accumulator capsules, F-series hydraulic tank seals and bolts, and diesel engine filters, sensors and bearing components**.
Each part carries a unique model identifier (SFZ2835.52-00, JK00213-19, YPQ-40A, etc.) for quick identification and targeted procurement. Raw materials are selected for extreme oilfield resilience: forged alloy steel for load-bearing shafts, high-temperature fluororubber for seals, hardened steel for wear components, 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 gates, control assemblies and sealing rings provide stable pressure containment up to 70MPa, preventing blowouts and ensuring strict well control safety compliance; positioning pins and fasteners secure BOP components for stable, long-term operation.
• Rig Power Transmission & Braking: ZJ series rig clutch hubs, drive shafts and brake valves deliver precise, reliable braking control to avoid operational accidents; sprockets and flanges ensure smooth torque transfer for winch and turntable operation.
• Drill Pipe Handling Stability: ZQ203 clamp jaw plates, flanges and connectors enable secure, precise gripping and rotation of drill pipes; transition plates and spiral rods reduce wear and ensure consistent clamping force, minimizing pipe damage.
• Control System Efficiency: FKDQ640/FKQ640 control box pressure transmitters, switches and valves monitor and regulate hydraulic/air pressure in real time, maintaining stable operation of rig control systems and preventing pressure fluctuations.
• Hydraulic & Engine Performance: F-series hydraulic tank seals and bolts prevent fluid leakage and maintain system pressure; diesel engine filters, sensors and bearings optimize combustion, reduce wear and extend engine service life.
3. Structural & Material Features
• Ultra-Precision CNC Machining: All structural parts feature ±0.01mm dimensional tolerance, ensuring 100% OEM fit without modification or adjustment during on-site installation, cutting installation time by 72%.
• Reinforced Multi-Layer Sealing: BOP sealing rings and hydraulic tank gaskets adopt a labyrinth design, effectively blocking dust, mud and high-pressure fluid leakage in harsh field environments, with a 99.9% leak-proof rate under rated pressure.
• High-Strength Wear Resistance: Load-bearing components use hardened alloy steel (65-71 HRC hardness); sealing parts use heat-resistant fluororubber that resists aging and cracking at temperatures ranging from -45°C to 295°C.
• Modular Quick-Change Design: Wear-prone parts (BOP seals, clamp jaw plates, brake components) use a modular structure, reducing on-site repair time by 92% 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) / 0-65MPa (rig winch & brake systems)
• Temperature Range: -45°C to 295°C (sealing components) / -35°C to 260°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/casing handling, cementing operations
5. Maintenance & Upkeep Recommendations
• Regular Inspection Cycle: Inspect BOP sealing components, clamp wear parts and winch shafts every 720 operating hours; check for wear, cracks or leakage, and replace damaged parts immediately to avoid safety hazards.
• Lubrication Protocol: Lubricate rig shafts, sprockets and clamp bearings with high-temperature lithium grease every 550 hours; replace hydraulic tank filters and diesel fuel filters every 2300 hours to prevent fluid contamination.
• Storage Requirements: Store spare parts in a dry, dust-free environment with relative humidity ≤55%; seal rubber seals and electronic components in anti-oxidation, anti-static packaging to prevent premature aging.
• 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 or abnormal noise occur.

On-Site Fault Repair Cases (Field-Verified Solutions)
Case 1: FZ35-35 BOP Short Hand Control Assembly Failure Repair
An offshore drilling rig faced BOP operation failure due to a faulty FZ35-35 short hand control assembly (SFZ2835.52-00), halting well control operations. Replacing the damaged assembly with our precision-engineered component restored full BOP control, fixed operational lag, and the BOP passed safety inspections for 17+ consecutive months.
Case 2: ZQ203-100 Jaw Plate Wear Fix
A land drilling team experienced frequent drill pipe slippage due to worn 8″ ZQ203-100 jaw plates, causing drilling delays and pipe damage. Installing our hardened steel jaw plates eliminated slippage, restored secure clamping, and extended component service life by 90% compared to standard aftermarket parts.
Case 3: ZJ45 High Speed Clutch Hub Breakdown Resolution
A ZJ45 drilling rig suffered power transmission failure due to a damaged 45-roller high speed clutch hub (106.02.20.34), halting winch operation. Replacing the faulty hub with our forged alloy steel component restored torque transfer, fixed power delivery issues, and the rig operated without recurring issues for 18+ months.
