Flexible Applications & Limitations of Small-Diameter DTH Hammers for Water Well Drilling Rigs

新聞 35 Views
The water well drilling rig often uses small-diameter DTH hammers (65-110毫米) as standard.

 

  1. Highly portable: Fits 3-6m³/min compressors, weighs <1.5 tons. Transportable by tricycle to remote areas.
  2. Ideal for rural shallow wells: A 50m orchard well took 3 days, costing 8,000 yuan. Damaged <5㎡ farmland.
  3. Has clear limits: Drills 1-2m/day in granite, yields <30m³/h. Poor stability in wells >100m.

 

Its moderate impact frequency (1000-1400/min) aids pipe installation. The water well drilling rig suits small-scale rural use.
