Abstract

Closed turbine wheel for centrifugal pumps.It includes two discoidal parts (2, 3) that are coaxial to the rotation axis (4) of the pump, from which the first (3), called a rim, is essentially flat, whilst the second (2), called a cube, is next to the rotation axis of the pump and has a plurality of helical channels (6). The cube (2) is attached to the rim (3) by peening towards the outside of the respective external snouts of a plurality of short hollow cylinder projections (9) produced by presses on the rim and are inserted into the respective holes (11) made on the bottom of the turbine blades of the cube, so that the edge of each of said external snouts of the cylinder projections of the rim is strongly applied against the edge of a corresponding pass-through hole of the turbine wheel.
