Product Description & Technical Performance Details

1. Product Introduction

This series covers more than 40 kinds of high-performance oilfield spare parts, including engine filters, special bearings, explosion-proof electrical appliances, hydraulic valves, sealing rings, fasteners, structural components and monitoring parts. Representative models include Caterpillar 326-1643 primary fuel filter, Weatherford 101866-001 roller bearing, ExdⅡCT4 IP65 explosion-proof plug-in, JC70DB drawworks BG80 series guide ring, and SL225 series swivel accessories. All products are made of high-standard raw materials, and each batch has passed factory performance testing to ensure consistent quality with original parts.

2. Core Function Description

• Filtration System Parts: Fuel filters (326-1643, 1R0755, PL-420) and oil filters (23530573, LF4112) efficiently remove impurities, moisture and carbon deposits in fuel and engine oil, preventing cylinder wear and fuel system blockage; filter elements are made of paper, synthetic canvas and metal materials to adapt to different oil quality conditions.

• Transmission & Bearing Parts: Roller bearings and bushings for hydraulic power tongs reduce friction during torque transmission, ensuring stable tongs operation; guide rings for drawworks safety caliper cylinders assist in precise movement of hydraulic components, avoiding eccentric wear.

• Electrical & Control Parts: Explosion-proof plug-ins, circuit breakers (NS160N, T5N400) and fuses provide safe power distribution and overload protection in explosive hazardous areas, meeting ExdⅡCT4 and IP65 protection levels; pneumatic reversing valves and shuttle valves control hydraulic oil flow direction to support braking and action switching.

• Sealing & Structural Parts: Airbags, inflation hoses and rubber kits provide reliable sealing for pneumatic and hydraulic systems; pins, screws and fork assemblies fix and connect power tongs components to resist heavy-load vibration; oil seal housings and swivel goosenecks protect internal transmission parts from external mud and dust erosion.

• Monitoring & Auxiliary Parts: Petroleum density meters, inclinometer cameras and magnetic locators realize downhole parameter monitoring and positioning; yield meter housings and scintillation crystals protect precision monitoring components to ensure data collection accuracy.

3. Structural Features

• High-Strength Material Configuration: Filter shells are made of thickened steel, bearings are made of high-hardness alloy steel, sealing rings are made of oil-resistant and wear-resistant rubber, and explosion-proof parts are made of flame-retardant and corrosion-resistant metal, with strong resistance to pressure, temperature change and chemical corrosion.

• Precision Machining Tolerance: The dimensional error of guide rings, bushings and pin assemblies is controlled within 0.01mm, ensuring perfect fit with host equipment and eliminating abnormal noise and wear caused by assembly gaps.

• Explosion-Proof & Sealing Design: Electrical components adopt ExdⅡCT4 flame-proof design, with IP65 dustproof and waterproof performance, suitable for Class 1 explosive gas places; hydraulic and pneumatic seals adopt multi-layer labyrinth design to enhance pressure retention capacity.

• Quick Installation Structure: Filter elements, airbags and rubber kits adopt modular design, which can be directly disassembled and replaced, shortening on-site maintenance time and reducing labor input.

4. Applicable Operating Conditions

• Pressure Range: Pneumatic and hydraulic parts withstand up to 350 BAR working pressure, block and bleed valves adapt to 5000 PSI high-pressure system.

• Voltage Adaptation: Electrical parts support 24V DC, 380V AC, 120V AC and other voltage specifications, matching oilfield conventional power supply systems.

• Environmental Adaptability: Suitable for onshore desert, offshore platform, low-temperature and high-humidity oilfield environments, resistant to salt spray, crude oil, mud erosion and mechanical shock.

• Standard Compliance: Comply with API 7K, API 16C, IECEx, GB70-86 and other international and domestic standards, suitable for global oilfield operation scenarios.

5. Maintenance & Practical Suggestions (Engineer Field Experience)

• Preventive Maintenance Cycle: Replace fuel and oil filters every 1000 operating hours, check airbag and sealing parts for cracks every 600 hours, and torque screws and pins to specified values every 300 load cycles.

• Avoidance Tips: Do not use filters of different materials interchangeably on the same engine; store explosion-proof electrical parts in a dry and sealed environment to avoid moisture damage; lubricate roller bearings with special high-temperature grease to prevent dry friction.

• On-Site Inspection Points: Before installation, check the flatness of sealing rings and the concentricity of bearings; test the conductivity of explosion-proof plugs and the tripping sensitivity of circuit breakers to ensure safe operation.

• Storage Requirements: Keep rubber and sealing parts away from direct sunlight and oil pollution; coat metal fasteners and bearings with anti-rust oil for long-term storage to prevent oxidation and rust.
