Customized Centrifugal Blower Fan Impeller For Power Generation

Industrial centrifugal fan single impeller blower wheel wear-resisting processing for industrial boiler

Classification of impeller

According to the blade Angle, the centrifugal fan wheel can be divided into forward-leaning impeller, radial impeller and back-leaning impeller.

According to the blade Angle of the impeller, the centrifugal impeller can be divided into three types: forward-leaning impeller, radial impeller and back-leaning impeller.

According to the impeller structure, the impeller can be divided into two types: multi-wing impeller and split impeller.

Forward-leaning impeller refers to an impeller outlet Angle greater than 90 degrees for the forward-leaning impeller, also known as the forward impeller. Generally speaking, from the perspective of the radial section of the wind wheel, the Angle between the lateral extension line of the blade and the reverse tangent line of the rotation direction of the blade at this point is obtuse, which is the forward leaning impeller.

Tilting impeller refers to the impeller outlet Angle less than 90 degrees for the tilting impeller, also known as the backward impeller. Generally speaking, from the perspective of the radial section of the wind wheel, the Angle between the lateral extension line of the blade and the reverse tangent line of the rotation direction of the blade at this point is an acute Angle, which is the back tilting impeller.

The blades of the multi-wing impeller are much more than the blades of the impeller, which are generally more than 30 pieces, and are uniformly distributed in the outer side of the upper and lower plates of the impeller. The diameter of the upper and lower plate edge of the impeller is generally the same.
