Lajme 239 Pamje
Water well drilling rig special maintenance focuses on five major components:

 

  1. Hydraulic system:
    Replace return oil filter every 50 hours to prevent ice chip blockage.
  2. Power system:
    Check antifreeze freezing point daily (must be 10°C lower than ambient temperature).
  3. Drilling tool system:
    Apply antifreeze lubricating grease (drop point ≥150°C) after use.
  4. Electrical system:
    Test cable insulation resistance weekly (must be >10MΩ).
  5. Cooling system:
    Let the engine idle for 10 minutes before shutdown to prevent thermal stress cracking.

 

Drills at Antarctica’s Kunlun Station have operated for 3 consecutive years without major failures following these regulations.water well drilling rigBangxin water well drilling rig
