Matching Principles for Water Well Drilling Rigs and DTH Hammers

A water well drilling rig must match DTH hammers well to ensure efficiency. Follow these rules:

 

  1. Power matching: Air compressor output fits hammer’s air needs. 110mm hammers need ≥3m³/min; too little slows impact, too much wastes energy.
  2. Torque coordination: Rig’s rotation torque must move the hammer. Hard rocks need higher torque to avoid bit jams.
  3. Size compatibility: Hammer diameter matches drill pipes and bits. 150mm hammers fit 165mm bits and 178mm pipes.

 

A site once had 40% lower efficiency due to poor matching. Fixing it raised daily progress by 60%.

Proper matching makes the water well rig work best. The water well drilling rig thus maximizes DTH hammer performance.
