SD10A DTH Hammer SD10 Down The Hole Hammer For Hydrology and water
well drilling
Pneumatic impactor
Pneumatic impactor, also known as pneumatic impactor, pneumatic
dive hammer. To the compressed air as the power medium, the use of
compressed air energy to produce continuous impact load hole at the
end of power equipment.

Glossary: Pneumatic Impactor, Down The Hole Hammer
Pneumatic percussion hammer, pneumatic down-tme-hole hammer
Compressed air at the same time can also doubles as a wash hole
medium. Pneumatic impactor has high wind pressure and low wind
pressure, valve type and no valve type of points. Usually the
pneumatic impactor directly connected with the carbide rod tooth
drill to impact the way rock, low-speed rotation is not coring the
full drilling. Mainly used in hydrological wells drilling, no core
geological drilling, geological disaster prevention and control
projects and mine drilling and other fields. Suitable for use in
gravel and hard rock formations, specially configured drill bits
can also be used in soft soil. Mechanical drilling speed is
generally much higher than the hydraulic impactor drilling, but
need to be equipped with a larger capacity of the air compressor,
fuel consumption, noise, dust pollution. Drilling depth by the
groundwater level, the greater the impact of water.

Description:
It is a kind of high air pressure DTH Hammer without footvalve, our
newest design. It is also one of the most advanced DTH Hammers in
the world.
It has the following 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 the one with foot valve.
3. Simple structure, reliable parts, long life, easy and cheap
maintenance.
4. Lower air and oil consumption. The oil consumption is about 10%
lower than the one with foot valve.
