(1)Improve the centrifugal pump suction port to the impeller near the structural design. Increase the flow area; increase the radius of curvature of the inlet section of the impeller cover, reduce the rapid acceleration and decrease of the liquid flow; reduce the thickness of the inlet of the blade, and make the leaf inlet rounded

First,multi-stage centrifugal pump outlet pipe resistance is too large; pump direction of rotation; multi-stage pump impeller flow blockage or damage, pump speed is insufficient. Second, check or shorten the horizontal multi-stage pump outlet pipe to eliminate dirt or replace the impeller impeller; check the pump motor, increase the pump speed.
