Xinfeng Fan | Centrifugal Fan Performance in Ventilation Series

01 

Fan Structural Design

Currently, the fixed frame of this centrifugal fan equipment comprises distinct front and rear frames. However, after prolonged use, screws in either the front or rear frame may loosen. Failure to address these issues can severely compromise the fan's operational stability. Do not assume this problem is rare—many overlook how it impacts the centrifugal fan's power output.

Therefore, through design improvements, the centrifugal fan achieves stable operation, uniform exhaust distribution, and easy maintenance, enabling purification of discharged gases while preventing environmental pollution.

 Fan Equipped with Variable Frequency Drive

        Additionally, the fan's variable frequency drive can be adjusted to ensure the centrifugal fan operates at the optimal time, maximizing its true value. In practical application, the sub-flow channel is formed by a circular base plate, guide plate, and guide holes.

This allows turbulence generated by the primary airflow to flow along the secondary flow channel, thereby reducing noise caused by irregular turbulent passage. The secondary flow passes over the surface of the novel fan, thus serving a cooling function for the fan.

Fan Design Direction

Currently, the service life of the entire centrifugal fan has been extended. For many centrifugal fans, the aerodynamic design direction employing an outlet flow design represents their optimal operating point.

 After understanding the cause, different speeds were selected based on the user's proposed design processes, and variable tasks were predicted and optimized to ensure performance design conditions deliver efficiency to the user.
