More Information
Summary:An impeller assembly for centrifugal pumps has two disk members that have different diameters, are arranged coaxially to a rotation axis and face each other so as to form an interspace; blades are radially arranged in the interspace; the two disk members are also centrally provided with a fastening means for fastening to a transmission shaft, which rotates about the rotation axis. The particularity of the present invention resides in having contoured vanes that protrude radially from the peripheral region of the disk member that has the smallest diameter and are arranged substantially at the blades. 一种离心泵用的叶轮组件，其包括具有不同直径的两个盘构件，这两个盘构件与旋转轴线同轴地布置，并且彼此相向而形成有空隙，叶片径向布置在该空隙中，这两个盘构件还居中地设置有用于紧固至传动轴的紧固装置，传动轴绕所述旋转轴线旋转。本发明的特征在于，具有从直径最小的盘构件的外周区域径向突出的波状外形的动叶，这些动叶基本布置在所述叶片处。
