Detailed Product Description & Technical Parameters

1. Product Introduction

This comprehensive spare parts collection covers **ZJ series rig intermediate shafts, hubs, couplings and brake components, 35×35/35×70 BOP sealing rings, cylinder head nuts, thrust bushings and rubber cores, ZQ203-100/ZQ203-125 clamp spacer rings, columns and bearings, DQ40/DQ50/DQ70 top drive power supplies and jaw components, hydraulic tank positioning discs and safety valve parts, electric control box valves and sensors, and diesel engine filters, belts and instrumentation**.

Each part carries a unique model identifier (0104-08M, JK00213-30, RJ11148.09.10.01.08.00, 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 rectangular sealing rings, lip seals and rubber cores provide zero-leak pressure containment up to 70MPa, preventing blowouts and ensuring strict well control safety compliance; fasteners and thrust bushings secure BOP components for stable, long-term operation.

 Rig Power Transmission & Braking: ZJ series rig shafts, hubs and couplings ensure smooth torque transfer for winch and turntable operation; brake valves, filter elements and safety gear components deliver precise, reliable braking control to avoid operational accidents and equipment damage.

 Drill Pipe Handling Stability: ZQ203 clamp spacer rings, columns and bearings enable secure, precise gripping and rotation of drill pipes; brake discs and connectors reduce wear and ensure consistent clamping force, minimizing pipe damage and handling hazards.

 Top Drive & Control System Efficiency: DQ series top drive power supplies and jaw components optimize drilling accuracy and pipe handling; electric control box pressure relief valves and sensors maintain stable operation of rig electrical and hydraulic systems.

 Hydraulic & Engine Performance: F-series hydraulic tank parts maintain clean fluid flow and stable pressure; diesel engine filters, belts and instrumentation optimize combustion, prevent fluid leaks and monitor operating parameters to extend 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 60%.

 Reinforced Multi-Layer Sealing: BOP sealing rings and hydraulic seals adopt a labyrinth design, effectively blocking dust, mud and high-pressure fluid leakage in harsh field environments, with a 99.8% leak-proof rate under rated pressure.

 High-Strength Wear Resistance: Load-bearing components use hardened alloy steel (61-67 HRC hardness); sealing parts use heat-resistant fluororubber that resists aging and cracking at temperatures ranging from -45°C to 275°C.

 Modular Quick-Change Design: Wear-prone parts (BOP seals, clamp bearings, brake components) use a modular structure, reducing on-site repair time by 82% 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) / 0-45MPa (rig winch & brake systems)

 Temperature Range: -45°C to 275°C (sealing components) / -35°C to 240°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 circulation system upkeep

5. Maintenance & Upkeep Recommendations

 Regular Inspection Cycle: Inspect BOP sealing components, clamp wear parts and winch shafts every 620 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, couplings and clamp bearings with high-temperature lithium grease every 450 hours; replace hydraulic tank filters and diesel fuel filters every 1900 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: FZ35-35 BOP Gate Shaft Lip Seal Leak Repair

An offshore drilling platform experienced BOP pressure loss and fluid leakage due to a worn gate shaft lip seal ring (JK00213-30) on the FZ35-35 BOP, failing mandatory pressure testing. Replacing the damaged seal with our high-temperature fluororubber component eliminated leakage, and the BOP passed 70MPa pressure testing on the first attempt, resuming operations within 1 hour.

Case 2: ZQ203-100 Clamp Spacer Ring Wear Fix

A land drilling rig in the Middle East reported unstable drill pipe clamping and frequent jamming due to a worn spacer ring (0104-08M) on the ZQ203-100 clamp, causing operational delays. Installing our precision-machined spacer ring restored proper alignment, eliminated jamming, and extended clamp service life by 78% compared to standard parts.

Case 3: ZJ-45 Turntable Intermediate Shaft Breakdown Resolution

A ZJ-45 drilling rig suffered complete turntable rotation failure due to a damaged intermediate shaft (106.03.01.00), halting drilling operations. Replacing the faulty shaft with our forged alloy steel component restored torque transfer, fixed rotation issues, and the rig operated flawlessly for 13+ months of continuous use with no recurring problems.
