• Temperature Range: -40°C (arctic drilling operations) to 150°C (high-temperature well logging and engine 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, and well logging operations

6. Maintenance & Care Recommendations

6.1 Routine Maintenance Schedule

Inspect BOP air pump components and sealing rings every 600 operating hours, replacing worn parts at the first sign of leakage; replace engine, hydraulic and transmission filters every 1800 hours to prevent clogging and system damage. Check hydraulic power tong jaws, belts and springs for wear every 400 hours, lubricating with extreme-pressure hydraulic oil; test explosion-proof electrical components every 6 months for functionality and sealing integrity. Inspect drawworks springs and cylinder assemblies every 800 hours for fatigue, 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 drive components and BOP parts 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 logging tool accessories in a cool, dry area to prevent UV degradation, and never reuse deformed springs or worn seal 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 proper filtration efficiency.
