Abstract

PURPOSE: To make flow near a suction zone uniform, prevent an air blown vortex and an underwater vortex and improve the suction performance of a pump, by fitting the body of the pump or a suction pipe with a rectifying plate which divides the flow in a water vessel into an upper and a lower portions.
CONSTITUTION: A rectifying plate 6, which divides the flow in a water vessel 1 into an upper and a lower portions, is attached to a pump 3 or a suction pipe 4. An appropriate gap is set between the rectifying plate 6 and the wall of the water vessel 1. The plate is so placed in the vessel that water flows freely between the upper and the lower portions because of the gap. Only when the lower portion flows at lower pressure, the upper portion passes through the gap between the rectifying plate 6 and the wall of the water vessel 1 to only supplement the flow of the lower portion. At that time, the upper portion flows very slowly. Therefore, flow separation and vortexes hardly take place in the downstream part of the suction pipe 4. On the other hand, the lower portion is made directional by the rectifying plate 6 and exerts an effect to smoothly conduct the flow.
