Detailed Product Description & Technical Parameters

1. Product Introduction

This comprehensive spare parts collection covers **ZJ series rig drive shafts, friction drums, brake shafts and sprockets, 35×35/35×70/54×14 BOP cylinder liners, sealing rings, ram rubber cores and hinge seats, ZQ203-100/ZQ203-125A clamp universal joints, brake belts and rollers, FKQ640 control box pressure regulating valves and filters, F-series hydraulic tank crankshafts and safety valves, and diesel engine filters, hoses and sensor components**.

Each part carries a unique model identifier (03-01M, JK00214-38B-1, AF32002-09.09, 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: 35×35/35×70/54×14 BOP sealing rings, ram rubber cores and cylinder liners provide stable pressure containment up to 70MPa, preventing blowouts and ensuring strict well control safety compliance; hinge seats and bolts secure BOP doors for stable, long-term operation.

• Rig Power Transmission & Braking: ZJ series rig brake shafts, friction drums and sprockets ensure smooth torque transfer for winch and turntable operation; brake belts and return springs deliver precise, reliable braking control to avoid operational accidents and equipment damage.

• Drill Pipe Handling Stability: ZQ203 clamp universal joints, rollers and positioning handles enable secure, precise gripping and rotation of drill pipes; brake belts and pin shafts reduce wear and ensure consistent clamping force, minimizing pipe damage.

• Control System Efficiency: FKQ640 control box pressure reducing valves, regulating valves and filters monitor and adjust hydraulic/air pressure in real time, maintaining stable operation of rig control systems and preventing pressure fluctuations.

• Hydraulic & Engine Performance: F-series hydraulic tank components maintain clean fluid flow and stable pressure; diesel engine filters, hoses and sensors 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 78%.

• 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 (67-73 HRC hardness); sealing parts use heat-resistant fluororubber that resists aging and cracking at temperatures ranging from -45°C to 305°C.

• Modular Quick-Change Design: Wear-prone parts (BOP seals, clamp brake belts, friction drums) use a modular structure, reducing on-site repair time by 96% 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 305°C (sealing components) / -35°C to 270°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 780 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 rollers with high-temperature lithium grease every 600 hours; replace hydraulic tank filters and diesel fuel filters every 2500 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: ZQ203-100 Universal Joint Failure Repair

A land drilling rig experienced drill pipe handling jams and power transmission lag due to a worn ZQ203-100 universal joint (03-01M), halting tong operation. Replacing the damaged joint with our precision-forged component restored smooth power transfer, eliminated jamming, and the clamp operated flawlessly for 20+ months of continuous use.

Case 2: FZ35-35 BOP O-Ring Seal Leak Fix

An offshore drilling platform faced BOP pressure loss and safety non-compliance due to a faulty FZ35-35 O-ring seal (JK00214-38B-1). Installing our high-temperature resistant fluororubber seal eliminated fluid leakage, restored pressure integrity, and the BOP passed 70MPa pressure testing on the first attempt.

Case 3: ZJ32L6 Brake Shaft Breakdown Resolution

A ZJ32L6 drilling rig suffered brake failure and winch runaway risks due to a damaged brake shaft (AF32002-09.09), suspending hoisting operations. Replacing the faulty shaft with our hardened alloy steel component restored reliable braking, fixed safety hazards, and the rig operated without recurring issues for 21+ months.
