Adjusting hydraulic pressure is key for rig operation. water well drilling rig.Set it based on strata and depth to balance efficiency and safety.

 

  1. Initial pressure setting principles: New rigs or after part replacement, follow manuals. Shallow drilling (<50m): 10-15MPa; mid-depth (50-200m): 15-25MPa; deep (>200m): 25-35MPa.
  2. Dynamic adjustment by formation hardness: For hard rocks, raise pressure by 30-50%. Increase 2-3MPa step by step. A rig in granite upped pressure to 27MPa, speeding drilling.
  3. Coordinated pressure and flow adjustment: Pair pressure (torque) and flow (speed). Soft strata: lower pressure, higher flow. Dense layers: higher pressure, lower flow.

 

Calibrate relief valves after adjustment, then lock knobs to avoid mishaps. Mastery boosts rig efficiency and adaptability.水井鑽機
