DTH Hammer Tech Requirements for Deep Well Hard Rock: Water Well Drilling Rigs

News 17 Views
The water well drilling rig needs high-pressure large-diameter hammers (1.6-2.0MPa, 180-250mm) for >250m hard rock.

 

  1. High performance: 1800-2000 impacts/min with HRC≥65 alloy parts. Drills 10-15m/day even at 300m depth.
  2. Powerful for quartzite: A 200mm model hit 800J/impact, doubling medium-deep well capacity in 200m quartz.
  3. Strict tech specs: <15% pressure loss at 300m, >120℃ heat resistance, 100+hr continuous work.

 

Heavy rigs (>8 tons) cut well slope by 50%. The water well drilling rig relies on these for ultra-deep hard rock.
