The flip of the rotor with radial flow with pressure reduced and more useful life; the rotor radial centrifugal tension and increased with reduced useful life and method for reducing the tension in a centrifuge rotor flapThe wheel hub with radial flow in the edge of the flap forming an opening for axial flow

摘要

A kind of stress is reduced and the fluid impeller blade that obtains prolonging working life, and this blade has that a hub from blade extends and part forms the edge of axial fluid flow boundary.This edge at least in its end with about 2 ° to about 20 ° angles with by at the radial line axially-spaced at the edge of blade hub deeply to blade, thereby the quality with the blade material of centrifugal action to the edge at blade hub place is reduced.
