The water well drilling rig DTH hammer achieves high efficiency through its unique working principle:
-
Energy input:
The water well drilling rig air compressor sends high-pressure gas into the hammer,
pushing the internal piston to reciprocate.
-
Impact generation: The piston hits the bit tail at high speed due to air pressure difference, converting gas pressure into mechanical energy.
-
Energy transfer: Impact energy passes through the bit’s alloy teeth to rocks, breaking them. The rig rotates the hammer for continuous drilling.
Its energy transfer efficiency reaches 60-80%,
much higher than mechanical impact’s 30-40%.
This explains its high efficiency in hard rock.
