What Are The Different Types Of Impeller Vane

QQ截图20210415161410Various types of impeller vane shapes are used in centrifugal pump engineering. They include the conventional axial, mixed flow and radial vane forms; however, a differentiation between different flow directions (i.e. from the inside to the outside or vice versa) is not made.
The vanes of a centrifugal pump are either permanently fixed to or fitted in the impeller or diffuser so as to allow adjustment.
The external shape of the vane is usually given as a circular projection in the meridian section (longitudinal section along the pump’s rotation axis). Various types of impeller vane shapes are used in centrifugal pump engineering.
A pump with such receiving guide vanes is called a turbine pump. The angles of the guide vanes at their receiving tips are such that the water enters the guides without shock. The guides are fixed over a circular ring. The ring with the guide blades is called a diffuser.
