Abstract

The invention comprises integrated axial front and back stages. The front stage fan bucket impeller has a bucket-shape forward bended rectangular main runner screw-coiling round the hub. The back stage helical centrifugal impeller has a main centrifugal runner and a branch backward bended rectangular centrifugal runner. The forward bended runner of the front stage is in communication with the backward bended runner of the back stage to form an integrated impeller.

Description

Technical field:

[0001] The present invention relates to a fluid conveying equipment and the application method of the equipment in fluid conveying, in particular to the design scheme of the core working component impeller applied on the impeller type fluid conveying machinery, more specifically, the turbofan bucket of the present invention The spiral centrifugal impeller is applied to the vane type fluid conveying machinery. The impeller is driven by the prime mover to rotate and work, and energy is input to the fluid to accelerate the pressure of the fluid and drive the fluid to flow, so as to achieve the function of conveying the fluid. Background technique:

[0002] At present, the single fan impeller or propeller impeller used in the blade type fluid conveying equipment and the axial flow fluid conveying machinery operates as the axial front sucks the fluid through the curved surface of the impeller blade, accelerates and pressurizes, and then outputs it axially. . The...
