High-Pressure DTH Hammers: Irreplaceable in Hard Rock Deep Wells for Water Well Drilling Rigs
The water well drilling rig relies on high-pressure DTH hammers (1.3-2.0Mpa) for hard rock deep wells.
- Powerful for hard rocks: Fits ≥15m³/min compressors. Drills 10-15m/day in 150m granite or basalt wells.
- High-frequency, high-strength impacts: 1600-2000 times/min. HRC≥65 teeth break rock crystals directly.
- Has drawbacks: Uses 2.5L fuel/m, 60% more than medium-pressure. Costs 3x low-pressure models.
A mine’s 300m well drilled 120m granite 2.5x faster. The water well drilling rig needs it for deep hard rock.
