SIDE CHANNEL LIQUID RING PUMP AND IMPELLER FOR SIDE CHANNEL LIQUID RING PUMP

摘要

A liquid ring side channel pump including a housing (102) defining an impeller cavity (106) with an inlet port (108) and a discharge port (110). An impeller (104) is positioned within the impeller cavity (106) for rotation about a central rotational axis (118). The impeller (104) includes a central hub (120) defining a conical outer surface and a plurality of angularly spaced apart main vanes (122) extending radially outward from the conical outer surface relative to the central rotational axis (118). The inlet and discharge ports (108,110) may be located on a same side of the pump housing (102). A method of pumping an air/fuel mixture is also disclosed.
