3.3 Hydraulic Power Tong Functions

ZQ203-100 hydraulic tong pins (0102-31M) secure mechanical assemblies, enabling high-torque pipe makeup and breakout; backing rings and mud pipe components reduce friction and prevent debris contamination; power lubrication assemblies ensure smooth mechanical operation under heavy load conditions.

3.4 Electrical & Auxiliary Functions

Explosion-proof plugs, connectors and buttons meet hazardous zone safety standards; circuit breakers and power supplies protect rig electrical systems; integrated inclinometers and dial gauges enable precise drilling monitoring; heavy-duty studs, nuts and washers secure critical rig assemblies, ensuring structural stability.

4. Structural Features

• High-Wear Resistance Design: BOP plunger components use corrosion-resistant copper sheathing; engine filter media features multi-layer pleated construction for high dirt-holding capacity; load-bearing pins and bearings use hardened alloy steel for extended service life.

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

• Explosion-Proof Compliance: Electrical components meet ExnAⅡT4/ExdⅡBT6, IP67/IP54 and WF1 standards, designed for NEC Class I Division 2 hazardous gas zones in oilfields, with non-sparking construction.

• Heavy-Duty Sealing: Gaskets, sealing washers and outer cylinder seals use oil-resistant NBR rubber, withstanding 5000PSI BOP pressure and extreme temperature fluctuations without leakage.

• ASTM-Certified Fasteners: Full-thread studs and nuts comply with ASTM A193-B7M/A194-2HM standards, with zinc plating for corrosion resistance in offshore and high-humidity environments.

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 fuel/air systems up to 120PSI

• Temperature Range: -35°C (arctic drilling operations) to 125°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, MCC electrical cabinets, and rig mechanical assemblies

6. Maintenance & Care Recommendations

6.1 Routine Maintenance Schedule

Inspect BOP air pump plunger sheathing and piston rings every 600 operating hours, replacing worn parts at the first sign of leakage; replace engine air/fuel/transmission filters every 1800 hours to prevent clogging and component damage. Check hydraulic tong pins and backing rings every 400 hours, lubricating with extreme-pressure hydraulic oil; inspect explosion-proof electrical connectors and fasteners every 800 hours for wear or corrosion. Calibrate sender units and dial gauges every 6 months to ensure accuracy, 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 BOP plunger components and engine gaskets 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 seals and filter elements in a cool, dry, dark area to prevent UV and moisture degradation, and never reuse deformed or cracked seals. Use only compatible lubricants for BOP and tong systems to avoid valve blockages, and clean filter housings thoroughly before replacing filter elements to ensure full filtration efficiency.
