摘要： Integrally formed stamping sheet-metal blades having 3D structure for impeller or diffuser of a centrifugal pump or blower includes at least two integral forming blade or vane members. Each blade or vane member has a plurality of relatively short 3D blades or vanes extending radially outward and an engaging edge of selected shape. Two or more blade or vane members may be positioned and stacked together through mating the engaging edge and be spot welded to form a complete impeller or diffuser assembly. The blade or vane may be joined to form a completed smooth blade or vane, or may be spaced from each other to form a multi-row blade or vane assembly. The impeller and vane assembly may be made with less number of stamping molds and jigs. Production is less expensive. Positioning and assembly of the blade and vane is easier at a lower cost.

摘要： Side-channel centrifugal pump in sectional construction, the stage packs of which comprise a suction connector (6), a pressure connector (7), a vane (10) and a casing shell element (8, 9). In order to reduce the structural complexity, the suction and pressure connectors (6, 7) are formed as sheet-metal parts and are disposed in an annular casing shell element (8, 9). The centering of the suction and pressure connectors (6, 7) is expediently effected from the shaft.
