2 Inch - 12 Inch Down The Hole Hammer Medium High Air Pressure Wear Resistant
Description
DTH drilling tool is a kind of drilling system which uses compressed air as motivation, makes drilling impact motivation parts down the hole, to control the piston reciprocating motion by the distribution device in the hammer, and then impacts the DTH bit in the front of the hammer to transit the impacting power to the bit. The DTH bit in the front of the hammer breaks the rock to drill hole.
At present, DTH drilling tool is 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. At the drilling hole of dia.105mm-dia.254mm, a plenty of the DTH drilling tools are used.
Application
Down The Hole Hammer is mainly used in underground mining and quarrying ,water well drilling
Advantages:
-Valveless air distribution. More reliable.
- Simple design of the piston. Long life.
- More efficient energy transfer, fact drilling speed, lower air consumption and lower oil consumption.
- Fewer internal parts, simple structure, long life, less failure and easier to maintain because all the parts are heat treated.
- Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
