The water well drilling rig and DTH hammer work better with these coordination skills:
-
Startup sequence:
Turn on the air compressor first.
Lower the bit to touch rock after stable pressure.
Then start the rotation system.
-
Drilling rhythm: Lift the bit every 30-50cm drilled. Use airflow to clear bottom cuttings, avoiding repeated crushing.
-
Parameter linkage: For hard rock, use “high impact + low rotation” (1500 impacts/min, 30 rpm). For soft rock, “low impact + high rotation”.

These tips help the water well drilling rig and hammer team up, boosting overall efficiency.
