Model 4-79 centrifugal fan can be used for indoor ventilation and ventilation in general factories and large buildings. It can be used to input or export gas, and the type of gas transported is air or other non-spontaneous combustion. Non-self-detonation, non-winding, harmless to human body, non-corrosive gas to iron and steel material. No viscous substance in gas. The dust and hard particles are not more than 150 mg / m3. The gas temperature should not exceed 80 ℃.

 

 

The fan can be made into clockwise rotation or counterclockwise rotation. Facing squarely from one end of the motor, the impeller rotating clockwise is called the clockwise whirlwind machine, which is expressed as "clockwise", and vice versa as the reverse whirlwind machine.

 

 

The model 4-79 fan is mainly composed of shell, impeller, inlet and motor. In addition to the above part, there are transmission parts.

 

Impeller-consists of tilting circular arc thin plate blade, curve front plate and flat plate rear disc, all made of steel plate and corrected by static and dynamic balance, air performance is good, efficiency is high, noise is low, operation is stable. 3. 5 is composed of 12 leaves, 4. 5 is composed of 14 leaves, and more than 5 is composed of 16 pieces.

 

Housing-made into two different types, the 3-12 housing is integrated and can not be disassembled; the 14-20 housing is made into two open types, divided in two halves along the middle horizontal plane and connected by bolts.

 

Inlet-made into a whole, installed on one side of the fan, parallel to the axial section of the curve shape, can make the gas enter the impeller smoothly, and the loss is relatively small.

 

Transmission-consists of spindle, bearing box, rolling bearing and belt wheel.
