Product Description
Impeller structure
A fan impeller is usually composed of a blade, a wheel and a bearing. Among them, the blade is a key part of the impeller, responsible for converting wind energy into mechanical energy and driving the entire impeller to rotate. The shape and number of blades can be designed and adjusted according to different application requirements. The wheel is the skeleton of the impeller, which holds the blades in place and supports the entire structure. The roulette wheel is generally made of metal material to provide sufficient strength and stiffness. The bearing is responsible for supporting the rotation of the impeller, reducing friction and resistance, and ensuring the smooth operation of the impeller.

Working principle of impeller
Fan impeller is a device driven by wind to rotate, often used in the fields of wind energy conversion, ventilation equipment and gas transmission. It is one of the most core and important components in the fan, and plays a key role in converting wind energy into mechanical energy. This paper introduces the structure, working principle and main application field of fan impeller.
