Abstract
The utility model relates to the technical field of centrifugal fans, in particular to a centrifugal fan impeller which is provided with a main plate. The middle of the main plate is provided with a hub shaft mounting hole, and a circular side plate is arranged outside the main plate. The side plate and the axis of the hub shaft mounting hole form an included angle of 75 DEG. A baffle is parallel with the side plate. The rotary blades, each having a suction inlet, are disposed between the side plate and the baffle. The main plate, the side plate and the baffle are all made of carbon steel. The centrifugal fan impeller is reasonable and novel in structural design, high in centrifuging efficiency, widely applicable to fans, pumps and the like, and wide in range of application.
Description
Technical field
The utility model relates to the centrifugal fan technical field, specifically relates to a kind of centrifugal fan impeller.
