Guide wheel for centrifugal pump - incorporates convex section on concave blade

摘要

The guide wheel is for centrifugal pumps of radial and semi-axial design. The concavely formed blade side (5) of the guide blade (2) proceeding outwardly from the edge (3) is provided with a convexly shaped contour (P). The convex contour can amount to up to one third of the guide blade length. USE/ADVANTAGE - Guide wheel for radial pump in which stresses occurring during part-load operation are avoided.
