The water well drilling rig requires high-pressure hammers (1.3-1.6MPa) for 150-250m hard rock.
-
High-frequency impact: 1600-1800 times/min breaks hard crystals. Drills 5-6m/day in granite stably.
-
Shortens drilling time: A 150mm model cut 40% time in 120m granite vs. medium-pressure types.
-
Match large compressors: ≥15m³/min keeps
pressure at 200m. Short stroke (30-50mm) saves 25% energy.
Lubrication systems boost frequency stability to over 85%. The water well drilling rig depends on these for hard deep drilling.
