The operating power of the centrifugal fan increases with the increase of the air volume, and the running power of the axial fan decreases with the increase of the air volume. When the centrifugal fan starts, the air valve needs to be completely closed and then opened slowly. Prevent the fan from burning the generator if the DC is too large, and the axial fan needs to be fully opened when it starts, and then gradually open to the required volume of air
The secondary difference between centrifugal fans and axial fans is:
1. The centrifugal fan changed the flow direction of the medium in the air duct, while the axial fan did not change the flow direction of the medium in the duct;
2. the front-end device is simple;
3.The front-end generator and the fan are normally connected through the shaft, the latter generator is normally in the fan;
4.The front-end equipment is in the air conditioning group, entrance, boiler drum, fan, and so on. The latter is often installed in the air duct, or in the air duct inlet of the former.
Centrifugal fan is a machine that relies on output machine energy and progressive gas pressure side by side . It is a driven fluid machine . The centrifugal fan is widely used for wind , dust and icing of industrial fields , tunnels , tunnels , icing towers , vehicles , ships and constructions ; Wind and Induced Wind of Boiler and Light Industry Furnace Ice and ventilation in the atmosphere conditioning facilities and household appliance facilities ; drying and selecting grain ; Charging and promotion of wind tunnel honey source and harmony cushion ship .http://www.jnblower.com/
