MAGNETIC FLOATATION PUMP WITH DYNAMIC BEARING

摘要

PROBLEM TO BE SOLVED: To provide a compact axial-flow pump having a reduced radial dimension. SOLUTION: This magnetic floatation pump comprises a rotary shaft body comprising an axial-flow blade and a dynamic bearing on its peripheral face, and including permanent magnets on its both ends, and magnetic connecting means respectively mounted on both ends of the rotary shaft body oppositely to the end part of the rotary shaft body, the rotary shaft body is rotated by at least one of the magnetic connecting means, and the rotary shaft body is kept in a floated condition by the cooperation of two magnetic connecting means and the dynamic bearing, whereby the fluid flows from one side in the rotary shaft direction to the other side by the rotating rotary shaft body.
