Working Principle
SOLLROC DTH hammer consist of only two moving parts: the piston and
the valve. With so few moving parts, the smart solution delivers
reliable high performance drilling in the most challenging
conditions. Water, at up to 180 bar delivery pressure, is used to
power the impact mechanism of the hammer at a high frequency rate.
When the water leaves the hammer, it loses the pressure and keeps a
low flush velocity. This however is still adequate to bring any
cuttings to the surface and clean the borehole. Additionally, the
hydrostatic column, which is created above the hammer, helps to
keep the hole stable while preventing potential collapse. This also
prevents water from being drawn into the borehole, which increases
hole stability and prevents potential environmental issues.
