Abstract

PURPOSE: To uniformalize the flow and decrease the turbulance of the flow into impeller vanes and decrease vibration and noise by setting guide vanes or guide grooves on a baffle board and uniforming the flow direction at both sides of the baffle board.
CONSTITUTION: A plurality of vanes 7 are attached to the back side b of a baffle board 5 so that the vector Vb of the flow velocity conforms with the flow velocity vector Va on the belly side a, Alternatively, guide grooves 8 instead of vanes can be machined on the back side b of the baffle board 5. Under this constitution, the direction of the flow velocity vector Vb of the inlet flow along the back side b of the baffle board 5 into the impeller conforms with the flow velocity vector Va of the inlet flow that comes into the impeller in a volute flow, once interrupted at the belly side of a baffle board 5. Thus, no turbulant flow due to the disagreement of velocity vectors Va, Vb takes place at the back side of the baffle board 5
