DTH Hammer Matching for Shallow Well Hard Rock: Water Well Drilling Rigs

خبر 33 طرق عرض
The water well drilling rig needs medium-pressure hammers (0.8-1.2MPa) for 50-100m hard rock.

 

  1. Balances energy and cost: Fits 8-12m³/min compressors. Drills 8-10m/day in limestone at 1200-1600 impacts/min.
  2. Better efficiency than low-pressure: A 110mm model doubled speed in 30m limestone, keeping well slope <1°.
  3. Match bits wisely: Sharp teeth for hard rock, flat for soft layers. Handles mixed strata, cutting costs by 30%.

 

Weighing under 3 tons, it balances mobility and efficiency. The water well drilling rig performs best with this match.
