Abstract

1412215 Centrifugal pumps JONKOPINGS MEKANISKA WERKSTADS AB 4 Jan 1973 [12 Jan 1972] 568/73 Heading F1C A centrifugal pump 3 is connected via a separator tank 2 and a suction pipe 1 to a container or tank (not shown) to be emptied, liquid being recirculated from the pump delivery pipe 6 to the pump inlet 4 only when the liquid in the separator tank is below a predetermined level, gas separated from the liquid in the separator tank being diffused into the recirculated liquid on the suction side of the pump, the resultant mixture of liquid and gas being pumped by the pump 3. A jet pump 9 is energized by liquid recirculated from a horizontal portion of the delivery pipe 6 via a pipe 8 containing a valve 10 which is opened, as by a switch actuated by a float 11, when the liquid level in the tank 2 falls, and draws in the gas via orifices 13 in a tube 12. The lower the liquid level, the more orifices 13 are uncovered by the liquid and hence the greater the flow of gas. The tube 12 may be covered by a slidable or rotatable sleeve for covering a selected number of the orifices 13. The mixture of liquid and gas may be directed towards the impeller eye to break down accumulations of gas or may be introduced into the pump with pre-rotation. A baffle 5 may be omitted.
