one Centrifugal ventilation and induced draft fan form :
Centrifugal ventilation and induced draft fan Single inhalation was used D-type transmission structure, fan and motor are connected by coupling. The fan body is mainly composed of casing, air inlet, rotor group (impeller and main shaft), bearing box, coupling and other parts. (the F-type transmission has double support and two bearing boxes. The single suction type has one air inlet chamber, and the double suction type has two air inlet chambers. C. Type B transmission has driving wheel and driven wheel.
Centrifugal ventilation and induced draft fan is composed of According to the needs of users, it can also be equipped with various external accessories, such as motor, regulating door, integral bracket, electric actuator, muffler, etc.
two Centrifugal ventilation and induced draft fan A brief introduction to the structure of :
two point one Centrifugal ventilation and induced draft fan Can be made into two types: forward or reverse: from one end of the motor face, such as the impeller clockwise rotation, called clockwise cyclone “ along ” Rotating counter clockwise is called counter fan “ inverse ” express.
The outlet position of the fan is indicated by the outlet angle of the casing “ along ” 、 “ inverse ” It can be made into 0 ° 、 45 ° 、 90 ° 、135 ° 、180 ° 、225 ° There are six angles. Other special angles can also be made according to the requirements of users.
According to the specific situation, there are two kinds of bearing boxes as follows:
（ 1） Water cooled bearing housing （ 2） Oil cooled bearing housing
