4-79 centrifugal fan air volume from 1900-20850 cubic meters/hour, wind pressure 176-2696 Pascal, Power: 0.75-5.5kw, low-pressure gale volume, there are ordinary, anti-corrosion type, explosion-proof type three specifications. Motor direct coupling, belt transmission, coupling transmission mode are
Type 4-79 centrifugal ventilators can be used for indoor ventilation and ventilation in general factories and large buildings. It is available both for the input of gases and for the output of gases, and the types of gases transported are air or other gases that are not spontaneous, self-exploding, non-winding, harmless to the human body and non-corrosive to steel materials. No viscous substances are allowed in the gas, and the dust and hard particulate matter are not greater than 150mg/m3. Gas temperature must not exceed 80 ℃, other similar performance can also be selected.
The fan can be made into a clockwise or counterclockwise rotation of two types. From one end of the motor to face, the impeller clockwise rotation is called Shun Cyclone machine, to "shun" means, on the contrary, called Inverse cyclone machine, to "inverse" representation.
The №3a-6a in type 4-79 fan is mainly composed of chassis, impeller, air inlet and motor.
In addition to the above parts, the №7C-20E also has the transmission part. Impeller-composed of rear tilt arc thin plate blade, curved front plate and plate rear disk, all made of steel plate and corrected by static balance, good air performance, high efficiency, low noise, smooth operation.
№3, no. No. 3.5 by 12 blades, №4, No. 4.5 by 14 blades, №5 above by 16 pieces.
Chassis-made of two different types, the №3-12 chassis as a whole, can not be disassembled, the №14-20 of the chassis made of two open, along the middle of the horizontal plane divided into two halves, by the bolt joint.
Inlet-made into the whole, mounted on the side of the fan, and the axial parallel section is curved shape, can make the gas into the impeller smoothly, and the loss is small.
Transmission-composed of spindle, bearing box, rolling bearing, belt wheel.
