Detailed Product Description & Technical Parameters
1. Product Introduction
This comprehensive spare parts collection covers ZJ series winch intermediate shafts, drive shafts and brake components, 35×35/35×70 BOP sealing rings, gate assemblies and pistons, ZQ203 drill pipe clamp wedges and connectors, TQ340 casing tong boom and speed measuring parts, hydraulic tank accessories, diesel engine seals and hoses, and rig auxiliary components, with unique model identifiers (106.05.01.00, DFZ5414-25, DFZ1310.01B-02, etc.) for quick identification and targeted procurement. Raw materials are selected for extreme durability: forged alloy steel for load-bearing shafts, high-temperature fluororubber for seals, hardened steel for brake blocks, and corrosion-resistant metals for hydraulic and BOP parts. Each part undergoes strict pressure testing, dimensional inspection and wear testing before shipment to guarantee consistent performance.
2. Core Function Description
• BOP Well Control & Sealing: 35×35/35×70 BOP W-shaped sealing rings, gate rubber cores, pistons and retaining rings provide zero-leak pressure containment up to 105MPa, preventing blowouts and ensuring well control safety compliance; screw plugs and flanges secure hydraulic connections and block fluid leakage.
• Winch & Turntable Power Transmission: ZJ series winch intermediate shafts, sprockets, gear sleeves and clutch assemblies ensure smooth torque transfer for rig hoisting and rotation; brake blocks and inertial brake assemblies deliver reliable, precise braking control to avoid operational accidents.
• Drill Pipe & Casing Handling: ZQ203 clamp wedge blocks, connectors and transfer cylinders enable secure pipe gripping; TQ340 casing tong boom, roller sets and speed measuring systems ensure stable, accurate casing operation, reducing pipe damage and handling risks.
• Hydraulic & Diesel System Efficiency: F-series hydraulic tank guide plates, universal shafts and jacking devices maintain stable fluid flow and system pressure; diesel engine water seals, hoses and filter elements prevent fluid leaks and optimize engine combustion efficiency.
• Rig Auxiliary Operation: Top drive pins, electromagnetic brake components and pneumatic winch motors support stable rig auxiliary functions; drilling fluid additives and solid control accessories improve drilling fluid performance.
3. Structural & Material Features
• Ultra-Precision Machining: All structural parts feature CNC machining with ±0.01mm dimensional tolerance, ensuring 100% OEM fit without modification or adjustment during on-site installation.
• Reinforced Sealing Design: W-shaped seals, O-rings and rubber cores adopt a multi-layer labyrinth structure, effectively blocking dust, mud and high-pressure fluid leakage in harsh field environments.
• High-Strength Wear Resistance: Brake blocks and shaft components use hardened alloy steel with a 58-62 HRC hardness rating; sealing parts use high-temperature fluororubber that resists aging and cracking under extreme temperatures.
• Modular Quick-Change Design: Wear-prone parts (BOP seals, clamp wedges, brake blocks) use a modular structure, cutting on-site repair time by 72% compared to traditional integrated components.
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: 0-105MPa (BOP & high-pressure hydraulic systems) / 0-30MPa (winch & brake systems)
• Temperature Range: -45°C to 255°C (sealing components) / -35°C to 220°C (mechanical structural parts)
• Environmental Types: Offshore saltwater platforms, arid desert drilling sites, cold-region oilfields, high-temperature deep well operations
• Application Scenarios: Routine rig maintenance, emergency fault repair, equipment refurbishment, well control operations, drill pipe/casing handling
5. Maintenance & Upkeep Recommendations
• Regular Inspection Cycle: Inspect BOP sealing components, winch shafts and brake blocks every 520 operating hours; check for wear, cracks or leakage, and replace damaged parts immediately to avoid safety hazards.
• Lubrication Protocol: Lubricate winch sprockets, shafts and clutch components with high-temperature lithium grease every 360 hours; replace hydraulic tank filters and diesel filters every 1500 hours to prevent fluid contamination.
• Storage Requirements: Store spare parts in a dry, dust-free environment with relative humidity ≤55%; seal rubber seals 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 and winch operation temperature; adjust valves and replace worn components if pressure fluctuations or abnormal noise occur.

On-Site Fault Repair Cases (Field-Verified Solutions)
Case 1: ZJ-45 Winch Intermediate Shaft Assembly Failure Repair
A land drilling rig in the Permian Basin experienced complete winch power transmission failure due to a damaged ZJ-45 turntable intermediate shaft assembly (106.05.01.00), halting hoisting operations. Replacing the faulty shaft assembly with our OEM-matched component restored torque transfer, fixed power delivery issues, and the rig operated flawlessly for 10+ months of continuous use with no recurring problems.
Case 2: FZ35-70 BOP Gate Rubber Core Leak Fix
An offshore drilling platform failed BOP pressure testing due to a worn 4-1/2″ gate rubber core (DFZ1310.01B-02) on the FZ35-70 BOP, causing fluid leakage and well control risks. Installing our high-temperature resistant rubber core eliminated leakage, and the BOP passed 105MPa pressure testing on the first attempt, resuming operations within 2 hours.
Case 3: ZQ203-100 Drill Pipe Clamp Wedge Block Wear Resolution
A desert drilling team reported frequent drill pipe slippage due to a worn wedge block (0101-29M) on the ZQ203-100 clamp, leading to operational delays and pipe damage. Replacing the worn wedge with our hardened steel component restored clamping force, eliminated slippage, and extended wedge block service life by 65% compared to standard parts.
