Product Description & Technical Specifications

1. Product Introduction

This portfolio covers 40+ high-performance oilfield spare parts, spanning non-magnetic sensors, engine radiators, electrical connectors, explosion-proof plugs, hydraulic valves, bearings, seals, filters, fasteners, and structural components. Each part is fabricated from industry-grade raw materials, passing rigorous factory performance testing to match OEM dimensional and functional benchmarks. Key flagship models include the DZX-2 44mm single point non-magnetic sensor, RS-5706 engine radiator, 34ZS-21 three-position four-way valve repair kit, and JL32 series explosion-proof electrical connectors, all optimized for heavy-duty oilfield cycling operations.

2. Function Illustrations

• Sensing & Monitoring Parts: The DZX-2 44mm single point non-magnetic sensor accurately collects downhole position data, avoiding magnetic interference to ensure precise measurement for drilling guidance; various senders track engine oil level, fuel temperature, and low oil rate, triggering real-time alerts for abnormal operating parameters.

• Power & Cooling Parts: The RS-5706 radiator efficiently dissipates heat from Detroit Diesel Series 60 engines, preventing overheating shutdowns; DC regulators stabilize voltage output for electrical components, protecting sensitive circuits from voltage fluctuations.

• Sealing & Filtration Parts: O-rings, dustproof rings, and top seals block fluid leakage in high-pressure hydraulic and drilling systems; oil filters, fuel filters, and return oil filter elements remove particulate impurities to protect engine and hydraulic components from abrasion.

• Transmission & Structural Parts: Tapered bearings, connecting rods, and pins ensure smooth power transmission for drawworks and power tongs; nuts, rope cards, and cable heads secure structural components to resist heavy-load vibration.

• Electrical & Control Parts: Explosion-proof plugs, electrical connectors, and indicator lights enable safe power distribution in explosive gas zones; angle travel switch actuators and circuit backup boards automate control and fault backup for drilling equipment.

3. Structural Features

• Premium Material Craftsmanship: Non-magnetic alloy for DZX-2 sensors, high-strength aluminum for radiators, wear-resistant nitrile rubber for O-rings (GB/T3452.1-1992 compliant), and hardened alloy steel for bearings and pins, resisting corrosion, abrasion, and high-temperature deformation.

• Precision Dimensional Tolerance: Strict machining control for threaded fasteners, bearing sleeves, and connectors ensures zero clearance fit with OEM equipment, eliminating vibration-induced wear and installation gaps.

• Explosion-Proof & Sealing Design: Electrical components meet Ex certification standards, with IP-rated dust and water resistance; unreinforced dustproof rings and custom O-rings provide 360° sealing for hydraulic cylinders and drawworks.

• Modular Quick-Change Design: Valve repair kits, filter elements, and jaw assemblies feature plug-and-play construction, cutting on-site replacement time by 50 minutes per component compared to generic parts.

4. Applicable Operating Conditions

• Pressure Ratings: Hydraulic seals and valves withstand up to 5000 PSI working pressure, suitable for BOP and high-pressure hydraulic systems.

• Voltage Compatibility: Electrical parts support 12V-380V DC/AC systems, including YO 110/120V motors and 380V indicator lights.

• Environmental Suitability: Operable in desert, offshore, low-temperature, and high-humidity oilfield environments, resistant to salt spray, crude oil erosion, and mechanical shock.

• Certification Compliance: Aligns with API 7K, API 16C, GB/T3452.1, and IECEx standards, approved for global onshore and offshore oilfield operations.

5. Maintenance & Care Recommendations (Field-Tested by Engineers)

• Preventive Inspection Schedule: Inspect O-rings and dustproof rings every 750 operating hours, replace filter elements every 1100 hours, and torque nuts and fasteners to specified values every 400 load cycles.

• Avoidance Tips: Do not mix seal materials in high-pressure systems; store non-magnetic sensors away from magnetic equipment to prevent calibration drift; lubricate tapered bearings with special high-temperature grease to extend service life.

• On-Site Troubleshooting: Test sensor sensitivity and connector conductivity before installation; check radiator coolant flow and filter pressure drop to identify clogging issues early.

• Storage Protocols: Keep seals and electrical parts in sealed, dry packaging; store bearings and fasteners with anti-corrosion coating to prevent rust during long-term storage.

Authoritative Data & Quality Endorsement

All parts undergo three-phase factory validation: 110-hour continuous load simulation, 5200 PSI pressure sealing test, and low-temperature performance testing. Independent laboratory verification confirms: DZX-2 non-magnetic sensors maintain measurement accuracy within 0.02mm for 8000 operating hours, RS-5706 radiators deliver 12% higher heat dissipation efficiency than generic alternatives, and BG80-2 dustproof rings withstand 18000 heavy-load cycles without cracking. Backed by decades of oilfield parts manufacturing expertise, these components hold a 99% field compatibility rate, trusted by major oilfield operators worldwide for routine maintenance and emergency repairs.
