Experimental Evaluation of Airlift Performance for Vertical Pumping of Water in Underground Mines.

ABSTRACT: This paper presents experimental studies on the optimization of air-water flow in an airlift pump. Airlift pumps use compressed gas to verticall transport liquids and slurries. Due to the lack of theoretical equations for designing and predicting flow regimes, experimental investigations must be carried out to find the best condition to operate an airlift pump at high efficiency. We used a new air injection system and different submergence ratios to evaluate the output of a simple pump for vertical displacement of water in an underground mine. The tests were carried out in a new device with 5.64 m height and 10.2 cm circular riser pipe. Three air-jacket pipes, at different gas flows in the range of 0.002-0.09 m³/s were investigated with eight submergence ratios. It was found tha
