Description:

The paper presents the analysis of results of investigations concerning an influence of applied constructive solutions on hydraulic operating conditions of a water-pumping air lift pump. The scope of the investigations encompassed the determination of flow rate and efficiency characteristics of an air lift pump having the discharge pipe with the internal diameter d = 0.04 m. The PM 50 mixer with a perforated rubber membrane, available on the market, as well as a mixer of own design, called circumferential mixer, were tested (the name origins from the fact that the mixer has the shape of a ring which encloses the discharge pipe on its whole circumference). The investigations were performed for three air-water mix delivery heads H: 0.40, 0.80, 1.20 m, for the specified pressure pipe submergence length h = 0.80 m. It has been stated that for both types of the applied mixers the water flow rate Qw increased along with the increase of the air flow rate Qa, reaching maximum, then decreased. However, in both of the applied mixers, the water flow rate Qw permanently decreased as the air-water mix delivery head H increased. The air lift pump achieved higher water flow rate Qw if the circumferential mixer was applied instead of that with perforated rubber membrane. It has been proved that for both of the applied types of mixers the air flow rate Qa in the air lift pump cannot be lower during water pumping than 5.0 m3×h-1 and should not exceed 15.0 m3×h-1 in case of the circumferential mixer and 16.0 m3×h-1 for the perforated rubber membrane mixer. The efficiency h of the tested air lift pump for both of the applied types of mixers decreased when the air-water mix delivery head H increased. The higher efficiency h, however, was obtained for the air lift pump with the circumferential mixer than for the perforated rubber membrane mixer.
