Detailed Product Description & Technical Parameters

1. Product Introduction

This comprehensive spare parts collection covers **ZJ series rig input shafts, sprockets, bevel gears and brake seals, 35×35/35×70 BOP pistons, gate plate assemblies and sealing components, ZQ203-100/ZQ203-125 clamp jaws, bolts, springs and covers, FKQ6406 console pressure transmitters, pipeline buckles and air tanks, F-series hydraulic tank bonnets, piston rods and gaskets, GT/NK/ND series rig chassis locks, oil seals and fasteners, diesel engine filters, sensors, injectors and gaskets, top drive connectors and relays, mud pump liquid end repair kits, and specialized drilling accessories like coring tongs, guide shoes and one-way pressure sealant DF-1**.

Each part carries a unique model identifier (BA70011-03.042, YPQ-25B, DFWS-40, 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 pistons, gate plates and sealing rings provide stable pressure containment up to 70MPa, preventing blowouts and ensuring strict well control safety compliance; retaining rings and repair kits maintain BOP structural integrity for long-term operation.

• Rig Power Transmission & Braking: ZJ series rig sprockets, input shafts and bevel gears ensure smooth torque transfer for winch and turntable operation; electromagnetic brake inserts and seals deliver precise, reliable braking control to avoid operational accidents and equipment damage.

• Drill Pipe Handling Stability: ZQ203 clamp jaws, bolts and activity pins enable secure, precise gripping and rotation of drill pipes; springs and forks enhance clamping force, minimizing pipe slippage and damage during handling.

• Control & Hydraulic System Efficiency: FKQ6406 console pressure transmitters and pipeline buckles monitor and secure hydraulic fluid flow; hydraulic tank bonnets and piston rods prevent fluid leakage and maintain stable hydraulic pressure.

• Engine & Generator Performance: Diesel engine sensors, injectors and filters optimize combustion and reduce wear; generator piston rings and gaskets maintain sealing integrity and extend power unit service life.

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 89%.

• Reinforced High-Temperature Sealing: BOP and hydraulic sealing components use fluororubber and nitrile rubber composites, resisting aging and cracking at -45°C to 330°C, with a 99.9% leak-proof rate under rated pressure.

• High-Strength Wear Resistance: Load-bearing rig components use hardened alloy steel (72-78 HRC hardness); clamp jaws and BOP gate plates use wear-resistant alloy coatings to extend service life.

• Modular Quick-Change Design: Wear-prone parts (BOP seals, clamp components, brake inserts) 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 330°C (sealing components) / -35°C to 295°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 operations

5. Maintenance & Upkeep Recommendations

• Regular Inspection Cycle: Inspect BOP sealing components, clamp wear parts and winch shafts every 900 operating hours; check for wear, cracks or leakage, and replace damaged parts immediately to avoid safety hazards.

• Lubrication Protocol: Lubricate rig sprockets, gears and clamp rollers with high-temperature lithium grease every 720 hours; replace hydraulic and engine filters every 3000 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: ZJ32L6 Input Shaft Assembly Replacement

A land drilling rig experienced winch power transmission failure and stalling due to a worn ZJ32L6 input shaft assembly (AF60001-02.05.00), halting hoisting operations. Replacing the damaged shaft with our forged alloy steel component restored smooth torque transfer, eliminated stalling, and the winch operated flawlessly for 27+ months of continuous use.

Case 2: FKDQ640-7 Pressure Transmitter Repair

An offshore drilling platform faced unstable hydraulic pressure monitoring and false system alarms due to a faulty FKDQ640-7 pressure transmitter (YPQ-25B), disrupting rig control. Installing our calibrated transmitter restored real-time pressure tracking, eliminated alarms, and the control system maintained stable performance for 25+ months.

Case 3: ZJ-40 Electromagnetic Brake Insert Replacement

A desert drilling rig encountered brake fade and unsafe stopping due to a worn ZJ-40 electromagnetic brake insert (FDWS-40), risking operational accidents. Fitting our high-friction brake insert restored reliable braking performance, eliminated fade, and extended brake service life by 95% compared to standard aftermarket inserts.
