What is the Model of our centrifugal  fans ?    

 YWL   2      D(E)     -130  -   QD     

   1       2       3           4          5     

1,YWL: External rotor Centrifugal` fan

2,Motor poles:2—2 poles,4—4 poles

3,E-- Single-phase motor,D--three-phase motor

4,Fan blade diameter:130—fan blade diameter is 130mm

5,Type code:QD-single inter air

What is structure of our  centrifugal  fans?     

Impeller: the blade type, curve of front coil and plate after plate.

Rotor: should be made of the dynamic balance and static balance, ensure the steady running, good performance.

Transmission parts: main shaft, bearing box, rolling bearing and belt pulley (or coupling).

What is the performance characteristics of our centrifugal  fans ?

1)High efficiency, low noise, small vibration, compact structure, beautiful appearance.

2) Centrifugal fan is actually a kind of variable flow constant pressure device. When the rotating speed is constant, pressure and flow theory of centrifugal fan curve should be a straight line.

3)The pressure produced in the centrifugal fan is affected by the large inlet temperature or density changes. For a given air inflow, the highest inlet temperature (lowest air density) when the lowest pressure. For a given pressure and the flow characteristic curve, there is a power and flow characteristic curve. When the blower run at constant speed for a given flow rate, the required power of inlet temperature, the higher.

 What is Product application areas of our centrifugal fans?       

Centrifugal blower is widely used in factories, mines, tunnels, cooling towers, vehicles, ships, and the structure of the ventilation, dust and cooling;The ventilation of the boilers and industrial furnaces and wind;Air conditioning equipment and household appliances in cooling and ventilation;Grain drying and submitted;Wind tunnel and become a hovercraft inflatable and propulsion, etc.
