| description | The utility model discloses a centrifugal fan, which comprises a fan casing, an air inlet and an impeller. The centrifugal fan is characterized in that the fan casing is provided with a connecting piece; the connecting piece is connected with the air inlet; the air inlet and the connecting piece can be axially adjusted in mounting position; the connecting piece is a flanged circular tube; the circular tube is connected with the fan casing through flanges; the circular tube is connected with the air inlet through bolts; bolt holes of the circular tube are axial elongated holes. The centrifugal fan disclosed by the utility model has the beneficial effects that the air inlet and the circular tube are adjusted in axial mounting position, and therefore the gap between the air inlet and the impeller is adjusted, and the performance of the centrifugal fan is adjusted further; the centrifugal fan is simple in structure and convenient in operation. |
