Centrifugal Fan Driving Modes Advantages and Disadvantages By Xianrun Blower

A Mode: Direct Driving
The impeller of centrifugal fan connects to the motor shaft directly, this is suitable for small airflow and pressure centrifugal blower. 
Advantage: saving the parts (such as belt pulley, belt, coupling, etc.), reliable performance.
Disadvantage: fixed speed. 

High Quality ID Fan for Ventilation

C Mode: Belt Driving
The impeller connects to motor shaft by belt pulley.
Advantage: adjustable speed, motor installation position is flexible. 
Disadvantage: Some parts are easy to break down, and need updating maintenance. 

High Temperature Fan For Metallurgical Factory

D Mode: Coupling Driving
The impeller connects to motor shaft by coupling, coupling drive centrifugal fan for high temperature, large airflow and high pressure condition. 
Advantage: stable operation, high efficiency. 
Disadvantage: fixed speed, high cost.

Wear Resistant ID Fan

Main shaft and coupling maintenance

Keep the main shaft clean,and remove dirt from shaft shoulder every year;

Please pay attention to the place where main shaft passes through shaft end seal of inlet chamber side plate, because condensation of small amount of air leakage will probably corrodes the place; 

centrifugal blower coupling

If the centrifugal blower runs for a while under unbalanced state, make straightness inspection to main shaft as far as possible;

Keep the coupling clean, and check the coupling connecting and fastening situation regularly.
