Application of DTH Hammers in Water Well Drilling Rigs

Noticia 43 Vistas
El Plataforma de perforación de pozos de agua depends on DTH hammers for efficient water well drilling.

 

  1. Small rigs (<30kW): Use low-pressure hammers (0.5-0.7Mpa, 65-110mm). Fits 3-6m³/min compressors. Drills <50m rural wells at 2-3m/h, cost <8,000 yuan/well.
  2. Medium rigs (30-50kW): Adopt medium-pressure hammers (0.8-1.2Mpa, 110-150mm). 1200-1600 impacts/min, drills 8-10m/day in limestone. Cuts costs by 30% in mixed strata.
  3. Large rigs (>50kW): Equip high-pressure hammers (1.3-2.0Mpa, 150-250mm). 1600-2000 impacts/min, drills 10-15m/day in 300m hard rock. Shortens time by 40%.

 

Wet hammers work better in water-rich areas; dry ones suit arid regions. Long-stroke models resist wear in fractured rock. The water well drilling rig gains more efficiency from smart adjustments now.
