Embodiment Construction
[0045] Next, a pump blade according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8 .
[0046] [the whole frame]
[0047] The pump vane of this embodiment has a plurality of flow paths communicating with the suction port coaxial with the rotation axis and the discharge port on the outer periphery, and the flow paths are logically arranged at equal angular intervals with respect to the rotation axis. Although the number of flow paths is not particularly limited, the cases shown in FIGS. 3 to 5 are embodiments in which there are two flow paths, and the cases shown in FIGS. 6 to 8 are embodiments in which there are three flow paths. The flow path is curved in a curved shape between the suction port and the discharge port. This pump vane can be manufactured by casting as an example. However, other metallic or non-metallic materials may be used as long as strength and corrosion resistance can be ensured.
