Structural Feature

Centrifugal fan generally consists of parts of air inlet, impeller,scroll case, outlet, gearing device,base andmotor.


(1) inlet:

 inlet is made into aninteger and set upatthe sideof scroll case of fan. Shapedconductor of axialcrosssecionof inletis streamline thecurrent canenterimpeller equablyso as to reduce iowloss and improveeficiency of impeller.


(2) Impeller

impeller is the most important part of centrifugal fan, its function is to invert mechanical energyin to gaseous static pressure energy and kinetic energy Impeller generally consists of front panel bladeback panel and axial panel (wheel hub).Through balanceable emendation operation will be smooth,and gas performance is good.


(3) Scroll case :

scroll case is the passage of gas current shaped conductor is usully Jog spiral with effect of current collection and guidance to oute Scroll case also has certan effect of pressure extension.


(4) Outlet:

a passage for gas to flow out of fan. Outlet is dilled with bolt hole andcan bel connected withairpipe.


(5) Gearing device:

consists of principal axis, bearinghousing, rolling bearing, pulley or clutch. One end of principal axis is connected with impeller, the other end is connected with pulley or clutch.



used to bear the weight of scroll case, bearingdeviceand motor, mantle and base are made into overallstructureItis notnecessary for the user to make and installthebasebyhimself making installation easy.
