This is a crucial issue. Whether a centrifugal fan impeller needs balancing depends primarily on vibration data, operating status, and component appearance. The specific methods are as follows:

The core of daily maintenance for centrifugal fans is "regular inspection, timely cleaning, standardized lubrication, and tight protection." Specific points are as follows:

This is a very useful question. Common centrifugal fan malfunctions mainly focus on vibration, abnormal noise, and performance degradation. The core malfunctions and their causes are as follows:

Centrifugal fans are fluid machines that rely on the centrifugal force generated by the rotation of an impeller to draw gas in axially and discharge it radially.
