When the centrifugal fan is working, the blades push the air in a direction perpendicular to the axis (i.e. radial), while the outlet is perpendicular to the axis. In most cases, using an axial fan can achieve cooling effect, but sometimes if a wind pressure of 90 degrees or greater is required, a centrifugal fan must be selected. Vibration is inevitable for centrifugal fans. Once the vibration of the centrifugal fan is too large, it will cause excessive motor current, high temperature rise, and in severe cases, the motor will burn out, causing significant damage to components such as bearings.
What is the reason for excessive vibration of centrifugal fans?
1. Reliability and stability of centrifugal fan manufacturers.
2. Is the installation of the centrifugal fan correct.
3. Environmental factors surrounding the operation of centrifugal fans.
How to reduce the vibration of centrifugal fans is a so-called policy measure?
1. Before putting the centrifugal fan into use, conduct a comprehensive inspection of the individual centrifugal fan to see if the appearance is damaged or deformed. Use a vernier caliper to measure whether the gap between the main shaft and the impeller meets the preset drawing.
Check if the regulating valve and current collector are functioning properly.
2. Install the centrifugal fan strictly according to the correct installation process, check the configuration of the shim and anchor bolts and the installation sequence of the parts, and then conduct an overall inspection of the equipment.
