Product Description

Product Description

 

 

 

Impeller structure

The centrifugal fan impeller is an important part of the centrifugal fan. After the air enters the impeller, it is caught by the high-speed rotating blades of the impeller and is also attracted by the negative pressure difference between the inside and outside. The rotation of the impeller creates centrifugal force, which pushes the inhaled gas outward. As the impeller rotates, the air is pushed to the outside of the centrifugal fan.

 

Product Brief

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.
