Hydrocyclone and Jet Sub
Atlas Copco Rock Drilling Tools - Secoroc Down the Hole Equipment
Dry Hole. Better Performance.
Fluids need to be injected to clean a drilled hole, and until Hydrocyclone technology drilling speeds were compromised as fluids were injected. Atlas Copco's exclusive, patented system expels injected fluids just above the down-hole drill. The result? As much fluid as necessary can be injected without concern for loss of performance. The hole stays clean, and the hammer runs as if it were operating dry.
Over the hammer Jet Subs allow large volumes of air to be bypassed above the hammer. This feature reduces operating pressure and allows more hole cleaning for deep, wet, or soft rock applications
