Abstract

PURPOSE: To provide a small but highly efficient pump by forming a semi-spiral water discharge channel into which a spiralling water flow is led in its entirety from an axialflow vane wheel and by installing a double-conical vaneless diffuser between the axial-flow vane wheel and the water discharge channel.
CONSTITUTION: The plane of a water discharge 2 chaninel is formed into a semi- spiral with its starting point S, in a quadrant between I and II which is made by two reference lines I-III, and II- IV. The reference line I-III passes through the center of the spiral and its direction is coincide with direction of the water flow. The reference line II-IV is orthogonal to the line I-III. A double-conical vaneless diffuser 1 is installed between an axial-flow va ne wheel 3 and the water discharge channel 2.
