Detailed Product Description & Technical Parameters
1. Product Introduction
This comprehensive spare parts collection covers **ZJ series rig brake blocks, disc brake butterfly springs, and drive shafts, 35×35/35×70 BOP support rings, dust rings, O-rings, and gate assemblies, ZQ203-100/ZQ203-125 clamp connecting rods, pistons, and clamping cylinders, DQ70 top drive back pin shafts and connecting shafts, F-series hydraulic tank bezels, stem guides, and stud bolts, electric control box valves, accumulators, and pressure switches, and diesel engine filters, belts, and piston rings**.
Each part carries a unique model identifier (1.14.09.01, JK00213-12, PSZ75-ZJ70D, 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 brake 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 support rings, dust rings, and O-rings provide zero-leak pressure containment up to 70MPa, preventing blowouts and ensuring strict well control safety compliance; gate assemblies and locking components secure BOP operation for stable, long-term performance.
• Rig Brake & Power Transmission: ZJ series rig disc brake butterfly springs, brake blocks, and drive shafts deliver precise, reliable braking control to avoid operational accidents; transmission shafts and sprockets ensure smooth torque transfer for winch and turntable operation.
• Drill Pipe Handling Stability: ZQ203 clamp connecting rods, pistons, and clamping cylinders enable secure, precise gripping and rotation of drill pipes; support rings and idler shafts reduce wear and ensure consistent clamping force, minimizing pipe damage and handling hazards.
• Top Drive & Control System Efficiency: DQ70 top drive pin shafts and connecting shafts optimize drilling accuracy and pipe handling; electric control box rotary valves, accumulators, and pressure switches maintain stable operation of rig electrical and hydraulic systems.
• Hydraulic & Engine Performance: F-series hydraulic tank components maintain clean fluid flow and stable pressure; diesel engine filters, belts, and piston rings optimize combustion, prevent fluid leaks, 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 65%.
• Reinforced Multi-Layer Sealing: BOP seals 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: Brake components and load-bearing shafts use hardened alloy steel (62-68 HRC hardness); sealing parts use heat-resistant fluororubber that resists aging and cracking at temperatures ranging from -45°C to 280°C.
• Modular Quick-Change Design: Wear-prone parts (BOP seals, brake blocks, clamp pistons) use a modular structure, reducing on-site repair time by 85% 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) / 0-50MPa (rig brake & winch systems)
• Temperature Range: -45°C to 280°C (sealing components) / -35°C to 245°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, mud pump system upkeep
5. Maintenance & Upkeep Recommendations
• Regular Inspection Cycle: Inspect BOP sealing components, brake blocks, and clamp wear parts every 650 operating hours; check for wear, cracks, or leakage, and replace damaged parts immediately to avoid safety hazards and operational delays.
• Lubrication Protocol: Lubricate rig shafts, sprockets, and clamp bearings with high-temperature lithium grease every 480 hours; replace hydraulic tank filters and diesel fuel filters every 2000 hours to prevent fluid contamination and component wear.
• Storage Requirements: Store spare parts in a dry, dust-free environment with relative humidity ≤55%; seal rubber seals and precision electrical components in anti-oxidation, anti-static packaging to prevent premature aging and damage.
• 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, maintaining pressure integrity.
• Performance Monitoring: Track hydraulic system pressure, engine temperature, and brake operation; adjust valves and replace worn components if pressure fluctuations, abnormal noise, or temperature spikes occur.

On-Site Fault Repair Cases (Field-Verified Solutions)
Case 1: ZJ70D Disc Brake Butterfly Spring Failure Repair
A land drilling rig experienced unstable braking and safety risks due to a broken PSZ75-ZJ70D disc brake butterfly spring, halting hoisting operations. Replacing the damaged spring with our high-strength alloy component restored consistent braking pressure, eliminated brake slippage, and the rig operated safely for 14+ months of continuous use.
Case 2: FZ35-70 BOP Gate Shaft Dust Ring Leak Fix
An offshore drilling platform reported BOP contamination and pressure loss due to a worn gate shaft dust ring seat (JK00213-35) on the FZ35-70 BOP. Installing our precision-machined dust ring seat blocked mud and debris intrusion, restored pressure integrity, and the BOP passed 70MPa pressure testing on the first attempt.
Case 3: ZQ203-100 Clamp Connecting Rod Wear Resolution
A desert drilling team faced frequent drill pipe slippage due to a worn connecting rod (0106-01M) on the ZQ203-100 clamp, causing operational delays. Replacing the worn rod with our forged steel component restored clamping alignment, eliminated slippage, and extended component service life by 80% compared to standard aftermarket parts.
