  1. Mud system:
    Flush pipelines daily with high-pressure water (≥10MPa) to prevent clay deposition.
  2. Power system:
    Check cooling system scale every 50 hours (thickness ≤0.5mm).
  3. Drill tool system:
    Apply anti-adhesion grease (drop point ≥120℃) after use.
  4. Electrical system:
    Test insulation resistance weekly (≥50MΩ) to prevent moisture short circuits.
  5. Hydraulic system:
    Replace anti-wear hydraulic oil every 100 hours (viscosity index VI≥140).water well drilling rig
