Cooling fan - Speed control systems
Dec 30 , 2021
Brushless DC (BLDC) fans are the most common type used to cool electronic equipment. Many cooling fans now have additional functions which provide greater control the fan speed and operation, thus improving the system performance. Having a fan run constantly even when maximum cooling is not required, does not result in an efficient system and can reduce the service life of a fan. If the average sp...

What should be paid attention to when installing centrifugal fan?
Feb 16 , 2022
First of all, when connecting the centrifugal cooling fan, the foundation joint surface, and the inlet and outlet air ducts, they should be adjusted to fit naturally, not forcibly connected, and the weight of the air ducts should not be concentrated on the casing to avoid deformation of the casing and affect the normal operation. The inlet and outlet air ducts of the centrifugal fan should be conn...

How to Repair and Maintain a Centrifugal Fan
Sep 22 , 2022
The basis of a centrifugal fan is a rotating blade wheel called an impeller, which drags the incoming air or gas into a circular motion. It is then pushed out of the fan by the centrifugal force created by the rotation. When entering and exiting the fan, the airflow changes direction. This is the centrifugal fan principle. In order to ensure the normal operation of the fan and improve the service ...
