Abstract
PURPOSE: To obtain big effect of uniforming of flow as well as to diminish less due to resistance to influx by installing small ribs for limiting the idling against counterflow to an impeller at the constricted part of the inlet port, and by installing big ribs for uniforming influent liquid at the opening end to widen the inlet port.
CONSTITUTION: A casing 1 has an inlet port 2 to widen through a constricted part 2a at the lower end toward the external direction, and an impeller 3 is housed in free command of rotating inside. Further, 4 denotes a rotary axle which supports the impeller 3, 5 denotes a guide shell arranged on the discharge side of the impeller 3, 6 denotes guide vanes installed around the circumference of the guide shell 5 and casing 1. Here, small ribs 7 for limiting the idling against counterflow to the impellers are protuberantly installed in small number of pieces in a bursting star pattern to the axial center of the impeller 3, while big ribs 8 for uniforming influent water are protuberantly installed in large number of pieces in a bursting star pattern to the axial center of the impeller 3 at the opening end to widen the inlet port 2.
