Hot sale! CE industrial exhaust fan

 

For us,mainly used for feed pellets making line and wood pellets making line.

 

Centrifugal fan is mainly used in the grain and feed processing factories for transport granule and powder stock by air.

 

The working principle of centrifugal fan with turbine compressor basic same, just because the gas pressure low velocity changed, generally do not need to consider the change, namely gas hematocr it gas as incompressible fluid handling.

 

Centrifugal fan variable flow is essentially a constant pressure device. When speedy centrifugal fan certain pressure flow theory curve should be a straight line.

 

 Due to internal loss, actual characteristic curve is curved. Centrifugal fan the pressure produced in by the inlet temperature or density change more tremendous influence.

 

 For a given the subsystem, the highest temperature (air density minimum) produced by the lowest for a given pressure.

 

 The pressure and flow characteristic curve, there was a power and flow characteristic curve. When blow with constant speed operation, for a given flow, the power needed with the reduction of the inlet temperature rise.
