Abstract
A method for manufacturing a propeller for a propeller pump includes providing a base propeller including a hub extending from an axial end in the axial direction, and a plurality of blades fixedly connected to the hub, each blade including a pressure side, a suction side, a leading edge, an initial trailing edge, and a blade tip extending from the leading edge to the initial trailing edge at the end of the blade facing away from the hub, trimming each of the blades of the base propeller the axial direction, and forming a modified trailing edge bye removing a part of the initial trailing edge along the entire pressure side from the hub to the blade tip.
Claims15
A method for manufacturing a propeller for a propeller pump, the propeller configured to rotate about an axial direction, comprising:
- providing a base propeller comprising a hub extending from an axial end in the axial direction, and a plurality of blades fixedly connected to the hub, each blade of the plurality of blades comprising a pressure side, a suction side, a leading edge, an initial trailing edge, and a blade tip extending from the leading edge to the initial trailing edge at an end of the blade facing away from the hub;
- trimming each of the plurality of blades of the base propeller in the axial direction;
- and
- forming a modified trailing edge by removing a part of the initial trailing edge along the entire pressure side from the hub to the blade tip,
- at each blade of the plurality of blades forming a final trailing edge by removing a part of the pressure side abutting against the modified trailing edge along an entirety of the modified trailing edge, so that a transition face is produced connecting the pressure side with the final trailing edge.
