Core Advantages of DTH Hammers in Hard Rock Drilling for Water Well Drilling Rigs

Tin tức 22 Views
The water well drilling rig DTH hammer excels in hard rocks like granite and basalt.

 

  1. High-frequency impacts: Its piston hits 1,000-2,000 times per minute. It crushes rock into fine particles, avoiding energy loss from traditional rotation.
  2. Concentrated energy: Converts air pressure to mechanical energy. Over 80% goes to bit teeth, no need for constant grinding.
  3. Deep well efficiency: Works well in wells over 100m. High-pressure air clears cuttings, keeping speed steady at 1-1.5m/h.

 

A mountain project used it in quartzite, drilling 12m/day. Traditional roller cone rigs only did 3-4m. The water well drilling rig saved much time.
