Abstract

PURPOSE: To eliminate formation of conterflow and noise and vibration caused in the area of low speed flow, by fitting a throttle plate, having openings whose areas of opening are smaller on the outer side than those on the pump axis side, on the upstream of an inducer.
CONSTITUTION: A throttle plate 11 is fitted at a place where a runner ring 8 has been placed or inside a suction bell mouth 4, thus forming a riser 11a composing a throttling section toward inside on the inlet side of water flow of the cylindrical runner ring 8. The riser 11a has many openings 11b to the direction of water flow which play a role of orifices for preventing counterflows. The area of holes 11b increases as they approach from the pump axis toward the periphery. This construction can mostly eliminate counterflows around an inducer 7 in the low flow area.
