Abstract
PURPOSE: To enhance a pump efficiency by preventing the water flow turbulence through straight- ening the flow in conformance with the out-going water flow angle while dividing a straightening vane in a water sending side into more than one water flow straightening pieces and also making each straightening piece or each straightening piece column in the side of the rotating vane to be capable of moving.
CONSTITUTION: If an operation rod 16 is operated in the direction shown by an arrow A, each frontal straightening piece 9 slants in the direction of the arrow A', and each rear straightening piece 10 makes a slanting motion in the direction of the arrow A" by means of each connecting plate 12 and 13, connecting rod 14 and a connecting rod 15. In this case, the straightening piece 10 is added momentum by the amount of θ/2 in addn. to the slanting angle of θ of the straightening piece 9. Similarly, if the operation rod 16 is operated in a direction of an arrow B, each straightening piece 9 and 10 makes a slanting motion of the predetermined value in the direction of an arrow B' and B" respectively, to form a row of the straightening piece. Thus by this mechanism, a straightening effect in accordance with the water flow angle which is sent out by a rotating vane 6 can be obtained by using the row of the straightening pieces made of each piece 9 and 10, hence, the separation or the collision of the flow can be prevented.
