Pressure adjustment methods and tips for water well drilling rig hydraulic systems

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.pajisje për shpimin e pusit të ujit
