The structure of the centrifugal fan

The centrifugal fan adopts a single suction D drive structure, and the fan and the motor are connected through a coupling. The main body of the centrifugal fan consists mainly of a casing, an air inlet, a rotor group (impeller and the main shaft) , a bearing casing and a coupling. The F gearbox has two bearing blocks, two bearing blocks, one single air intake chamber and two double air intake chambers. The C and B gearboxes have drive wheels and driven wheels.
In addition to centrifugal fan, centrifugal fan can also be configured according to customer needs a variety of external accessories. Common are: motor, regulating door, integral bracket, electric actuator, Silencer, etc. .
A centrifugal fan is called a “Clockwise” fan if the impeller rotates clockwise from the motor end, a anticlockwise direction fan, or an “Undo” fan.
The outlet angle of centrifugal fan shell indicates the outlet position: “Forward” and“Reverse” can be divided into six angles: 0: ° , 45 ° , 90 ° , 135 ° , 180 ° and 225 ° . Other special angle may also carry on according to the customer request.
Depending on the situation, the housing has the following two:
(1) water-cooled housing
(2) oil-cooled housing
