3. Function Description

3.1 BOP & Well Control Functions

9163800043 O-rings and BOP air pump sealing rings prevent air leakage in BOP control units, maintaining stable hydraulic pressure for safe well control operations; pop-up valves and valve groups regulate fluid flow, ensuring reliable BOP actuation and emergency shutoff capabilities.

3.2 Hydraulic Power Tong Functions

ZQ203-100 hydraulic tong components (GB1095-1979 splines, 0102-13M shafts, 0105-16M screws) enable high-torque pipe makeup and breakout; Weatherford 16-25 O-rings seal hydraulic passages to prevent fluid loss; backing rings and bushings reduce friction, ensuring smooth and stable tong operation under heavy load.

3.3 Engine & Electrical Functions

Detroit Diesel Series 60 rectifiers, diode holders and gaskets maintain engine electrical system stability and prevent fluid leakage; Honeywell oil pressure senders monitor engine oil pressure; AC contactors, solid state relay boards and fuses protect MCC cabinets and rig electrical systems from overload and voltage fluctuations; explosion-proof plugs/sockets ensure safe power connection in hazardous zones.

3.4 Drawworks & Mud Pump Functions

JC70DB drawworks brake pins secure safety caliper brake assemblies, ensuring reliable braking performance; hook springs and stopper assemblies stabilize traveling block hooks; mud pump filter elements remove contaminants from hydraulic oil, extending pump service life; viscometers and dispensing valves support drilling fluid testing and fluid control.

4. Structural Features

• High-Performance Sealing Design: BOP and power tong O-rings use oil-resistant, high-compression nitrile rubber, with precision-molded sealing surfaces to withstand 5000PSI working pressure without leakage, complying with API 16A standards.

• OEM-Matched Precision: All machined parts follow GB/T and API standards, with ±0.01mm dimensional tolerances for direct bolt-on replacement, eliminating modification and reducing installation time by 30%.

• Explosion-Proof & Safety Compliance: Electrical components meet non-sparking, IP54 and WF1 standards, designed for NEC Class I Division 2 hazardous gas zones in oilfields.

• Wear-Resistant Construction: Hydraulic tong shafts and splines use hardened alloy steel; engine gaskets use paronite composite for heat and pressure resistance; fasteners use corrosion-resistant zinc plating.

• Modular Compatibility: Electrical relay boards and valve assemblies feature plug-and-play design, enabling quick replacement and reducing repair downtime in field conditions.

5. Applicable Operating Conditions

These parts are engineered to perform reliably in the harshest oilfield environments, complying with API, GB, ASTM and NEC industry standards:

• Pressure Parameters: BOP systems up to 5000PSI, hydraulic systems up to 35MPa, engine systems up to 120PSI

• Temperature Range: -35°C (arctic drilling operations) to 120°C (high-temperature engine and hydraulic operations)

• Environmental Compliance: Hazardous gas zones (Class I Division 2), high-dust, high-humidity, offshore salt spray, and abrasive drilling mud conditions

• Application Scenarios: Land drilling rigs, offshore platforms, BOP control rooms, engine generator houses, hydraulic power tong stations, drawworks assemblies and mud pump systems

6. Maintenance & Care Recommendations

6.1 Routine Maintenance Schedule

Inspect BOP air pump O-rings and sealing components every 600 operating hours, replacing worn parts at the first sign of leakage; replace mud pump filter elements every 1800 hours to prevent clogging and system damage. Check hydraulic tong splines, shafts and screws for wear every 400 hours, lubricating with extreme-pressure hydraulic oil; test electrical relays, contactors and fuses every 6 months for functionality. Inspect drawworks brake pins and hook components every 800 hours for wear, and torque check all fasteners every 700 hours to maintain clamping force.

6.2 Engineer On-Site Tips & Pitfall Warnings

Always use OEM-specified torque values when installing engine gaskets and hydraulic components to avoid seal crushing or thread damage. Do not mix standard and explosion-proof electrical parts in hazardous zones, as this violates safety standards and risks gas ignition. Store rubber O-rings and sealing parts in a cool, dark, dry area to prevent UV and moisture degradation, and never reuse deformed or cracked O-rings. Use only compatible hydraulic fluid for BOP and tong systems to avoid valve blockages, and clean filter housings thoroughly before replacing filter elements to ensure full filtration efficiency.
