Detailed Product Description & Technical Parameters

1. Product Introduction

This comprehensive spare parts collection covers ZJ series winch drive shafts, sprockets, brake handles and oil throwing rings, 35×35/35×70 BOP sealing rings, shear rams, nuts and bolts, ZQ203-100/ZQ203-125 power tong jaw plates, U-shaped frames and air valves, TQ340-35 casing tong bearing seats and gear sets, hydraulic tank gaskets, pistons and safety valve assemblies, electric control box valves, transmitters and safety covers, and diesel engine filters, hoses and sensors, with unique model identifiers (SPC12-04, JK00213-15, DFZ1310.01C-02, 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. Each part 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 O-rings, gate rubber cores and shear ram assemblies provide zero-leak pressure containment up to 70MPa, preventing blowouts and ensuring strict well control safety compliance; fasteners and positioning parts secure BOP components for stable operation.

• Rig Winch & Brake Operation: ZJ series winch drive shafts, sprockets and brake handles ensure smooth torque transfer for hoisting; electromagnetic brake cables and friction components deliver precise, reliable braking control to avoid operational accidents.

• Drill Pipe & Casing Handling: ZQ203 power tong jaw plates, U-shaped frames and air valves enable secure, precise gripping and rotation of drill pipes; TQ340 casing tong bearing seats and limit mechanisms ensure stable casing operation, reducing pipe damage.

• Hydraulic & Control System Efficiency: F-series hydraulic tank gaskets, pistons and safety valves maintain clean fluid flow and stable system pressure; electric control box valves and transmitters ensure stable operation of rig electric and hydraulic systems.

• Diesel Engine Performance: Diesel engine filters, hoses and sensors optimize combustion, prevent fluid leaks, and monitor engine operating parameters to extend service life and avoid unexpected breakdowns.

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.

• Reinforced Multi-Layer Sealing: BOP O-rings and hydraulic tank seals adopt a labyrinth design, effectively blocking dust, mud, and high-pressure fluid leakage in harsh field environments.

• High-Strength Wear Resistance: Load-bearing components use hardened alloy steel (60-66 HRC hardness); sealing parts use heat-resistant fluororubber that resists aging and cracking at extreme temperatures.

• Modular Quick-Change Design: Wear-prone parts (BOP seals, power tong jaw plates, winch brake components) use a modular structure, reducing on-site repair time by 80% 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) / 0-40MPa (rig winch & brake systems)

• Temperature Range: -45°C to 270°C (sealing components) / -35°C to 235°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, power tong wear parts, and winch shafts every 600 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 420 hours; replace hydraulic tank filters and diesel fuel filters every 1800 hours to prevent fluid contamination.

• Storage Requirements: Store spare parts in a dry, dust-free environment with relative humidity ≤55%; seal rubber seals and precision components in anti-oxidation packaging to prevent premature aging.

• Installation Standards: Follow API rig maintenance specifications for torque tightening (BOP bolts, engine 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 fluctuations or abnormalities occur.

On-Site Fault Repair Cases (Field-Verified Solutions)

Case 1: ZJ-45 Winch Drive Shaft Breakage Repair

A land drilling rig in the Permian Basin experienced complete hoisting failure due to a fractured ZJ-45 winch drive shaft (106.02.30.06-1), halting drilling operations. Replacing the damaged shaft with our forged alloy steel component restored torque transfer, and the rig operated flawlessly for 12+ months of continuous use with no recurring issues.

Case 2: FZ35-70 BOP O-Ring Leak Fix

An offshore drilling platform failed BOP pressure testing due to a worn O-ring (JK00213-15, φ26.5*2.65) causing fluid leakage. Installing our high-temperature resistant O-ring eliminated leakage, and the BOP passed 70MPa pressure testing on the first attempt, resuming operations within 1 hour.

Case 3: ZQ203-125 Power Tong Jaw Plate Wear Resolution

A desert drilling team reported frequent drill pipe slippage due to worn 2-7/8″ jaw plate assemblies (19.148.00) on the ZQ203-125 power tong. Replacing the worn jaw plates with our hardened steel components restored clamping force, eliminated slippage, and extended jaw plate service life by 80% compared to standard parts.
