Definitions
- the object on which the invention is based is achieved by an impeller for a centrifugal pump, in which at least three blades are arranged between a front cover disc and a rear cover disc, the arc of the suction edge of at least one blade having a sinusoidal shape in the plan view of the inlet side of the medium to be conveyed a single turning point W.
- the suction edge is to be understood as the edge of each blade facing the flowing medium. Liquids, gases or, for example, suspensions can also be used as conveying media be used.
- the point of the arc that separates two parts of different curvature is to be understood as the turning point. What is meant here is the arcuate course that the viewer sees in the top view of the entry side of the medium to be conveyed.
- a preferred embodiment of the invention is that the turning point W is closer to the inner end B of the suction edge than to the outer end A of the suction edge. This measure allows the efficiency to be increased even further.
- the side of the rear cover plate facing the flow direction of the medium to be conveyed is convex.
- the arrangement of an otherwise conventional inlet spinner in the form of a bead-like projection is dispensed with.
- Fig. 1 shows the impeller for a centrifugal pump in a top view.
- Fig. 2 shows the impeller for a centrifugal pump in cross section.
- Fig. 1 is the impeller for a centrifugal pump in the
- the impeller for a centrifugal pump is shown three-dimensionally. It is usually made of plastic. Thermosets are used in a particularly advantageous manner.
- the impeller is particularly advantageously used in a centrifugal pump for conveying cooling water in a motor vehicle. The diameter of the impeller is then between 4 and 7 cm. Although such an impeller is designed to be relatively small, the centrifugal pump can achieve a relatively high efficiency.
