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.
