Low Air Pressure Down The Hole Hammer CIR 90 CIR110 CIR150 For
Water Well Drilling
Product APPLICATION:
DTH hammers and bits are widely used in underground mining,
quarries, hydraulic and Hydro-Power Engineering,
water well drilling, Mineral exploration, anchoring hole drilling,
geothermal engineering, Subway excavation, another civil
engineering.it has the advantage of high flatness, smooth hole wall,high rigid of drill rod and hammer,independent
of high axial thrust, no limit of drilling depth, low cost of
devices and easiness to maintain.
Product Description:
Advantages:
1:Out of the trouble of foot valve fracture and expansion and
contraction
2:Lower energy consumption and higher impact frequency,the drilling
speed is 15%-30% higher than conventional DTH hammers:
3:Simple structure,reliable parts,long life,easy and low cost
maintenance
4:Low air and oil consumption,the oil consumption is about 10%
lower than the conventional DTH hammers.
