Structured Product Description

Product Introduction

This comprehensive portfolio features over 60 mission-critical components spanning valves, bearings, filtration, sealing, transmission, electrical, and rig-specific categories, headlined by flagship models: R901051028 pressure relief valve cover, 141-7116 Caterpillar alternator belt, 45292C 3 1/2" bushing, and FILTREC-A1-20-GW03 hydraulic oil filter. Each part is fabricated from high-performance materials (hardened alloy steel, ceramic wear-resistant liners, HNBR/Viton sealing compounds, high-efficiency filter media) and complies with API, GB, Rexroth, and international industrial standards. All components undergo strict pressure testing, wear testing, and tolerance inspection to ensure seamless, modification-free installation on original equipment.

Function Description

• Hydraulic & Mud Pump Valves: Relief valve covers, pressure reducing valves, and ball valves regulate hydraulic/mud pressure (up to 35MPa) for mud pumps and BOP stations; quick release valves and throttle valves control fluid flow speed and safety shutoff.

• Filtration Components: Engine oil filters, hydraulic filters, air filters, and fuel pre-filters remove impurities, metal shavings, and sediment from fluids and air circuits, extending component service life by 28% and reducing abrasion damage.

• Sealing & Wear Parts: OEM-matched seal rings, O-rings, and Chevron packings provide zero-leak sealing in high-pressure systems; ceramic liners and wear plates enhance mud pump wear resistance and durability.

• Transmission & Structural Parts: Bearings, bushings, and rollers support heavy-load rig rotation; alternator belts and clutch assemblies enable smooth power transmission; cylinder and piston rod parts drive hydraulic actuation.

• Electrical & Control Parts: ABB circuit breakers, Allen-Bradley input modules, and pressure sensors deliver stable electrical control and real-time parameter monitoring for rig safety systems.

Structure Characteristics

• Precision OEM Tolerance: Critical sealing, bearing, and valve surfaces hold ±0.01mm dimensional accuracy, guaranteeing perfect alignment with original XJ-450/ZJ-50 and mud pump interfaces.

• Extreme Wear & Corrosion Resistance: Ceramic liners offer 5x longer wear life than standard steel parts; sealing compounds resist drilling fluid corrosion and high-temperature fatigue; hardened steel components withstand heavy-load impact.

• Modular Plug-and-Play Design: Filter cartridges, seal kits, and valve assemblies use modular construction, reducing on-site replacement time by 38% compared to custom-fabricated parts.

• Wide Pressure & Temperature Compatibility: Core hydraulic/mud pump parts support 0-35MPa pressure and -40℃ to 130℃ temperature ranges, matching harsh oilfield operating conditions.

Applicable Operating Conditions

These components are engineered to perform reliably in extreme oilfield and industrial environments, including:

• XJ-450/XJ-750/ZJ-50/315 drilling rigs (onshore/offshore sites, continuous heavy-load lifting and rotation)

• 3NB-1300F/3NB-1600F/F-800 mud pumps and SPM TWS-600S pumps (high-pressure mud circulation, abrasive drilling mud exposure)

• FKQ480X5 BOP hydraulic control stations (emergency pressure control, safety interlock operation)

• Caterpillar/Doosan power units and Sullair air compressors (continuous heavy-duty engine operation)

• ABB electrical control cabinets and rig sensor systems (stable power distribution, real-time monitoring)

Maintenance & Care Recommendations

• Filter Components: Inspect air/oil/hydraulic filters every 200 operating hours, replace cartridges every 800 hours; flush fluid circuits before new filter installation to remove residual debris.

• Valve & Sealing Parts: Check valves for leaks and seals for cracks/hardening quarterly; calibrate pressure relief/reducing valves semi-annually to maintain pressure stability.

• Bearing & Transmission Parts: Lubricate bearings and rollers with high-temperature lithium grease every 400 hours; inspect belts and clutches for wear monthly to avoid slippage.

• Electrical Parts: Inspect circuit breakers and sensors for dust/damage quarterly; test electrical connections annually to ensure reliable signal transmission.

• Storage Guidelines: Store parts in a dry, dust-free, ventilated area; retain original packaging to prevent corrosion, deformation, and contamination of precision components.

On-Site Fault Repair Cases

Case 1: 3NB-1600F Mud Pump Seal Failure

A 3NB-1600F mud pump suffered severe fluid leakage and pressure loss due to worn GH3161-27.01 seal rings and damaged piston rods. Replacing the OEM-matched seal kit and piston rod restored full pressure, eliminating downtime and extending pump maintenance intervals by 3 months.

Case 2: XJ-450 Rig Hydraulic Relief Valve Malfunction

An XJ-450 rig’s hydraulic system overheated and experienced pressure spikes due to a faulty R901051028 relief valve cover and clogged hydraulic filter. Swapping the valve cover and FILTREC-A1-20-GW03 filter normalized system pressure, preventing costly hydraulic pump damage.

Case 3: JC21D Drawworks Brake Block Wear

A ZJ-50 rig’s JC21D drawworks experienced unstable braking and abnormal noise due to worn 710750-00-0080 brake blocks. Installing new brake blocks and adjusting braking clearance restored full braking performance, ensuring safe rig operation within 1.5 hours.
