Centrifugal Fan And Rotary Blower | Backward Centrifugal Fan
4-72-C Model Features:
: Material Properties
:4-72-C type boiler centrifugal fan is designed to fit the equipment of heavy industries which can burn any kind of coal base and equipped with smoke and dust-removal device. It is applicable as long as the air volume and the performance are fit the condition. However, the highest temperature shall not exceed 130℃. Our company can provide the stainless steel heat boiler centrifugal fan when the temperature of air must exceed 130℃. It can be used on many occasions transfer materials, ventilation and improvide motivation to systems.
: Selection
: The centrifugal fan has single inlet, the model No. has No6,7,8,10,12,14,16, these kinds.
: The centrifugal fan can be made into two forms which are left-hand rotated and right-hand rotated. Face the fan from one end of the drive set. If the impeller rotates clockwise, we called it right-hand rotated, in short we use “right” for expression. If the impeller rotates anticlockwise, we called it left-hand rotated, in short we use “left” for expression.
: The position of the air outlet of the fan is indicated by the angle of the air outlet of the housing. “left” and “right” can be made into 0°,90°,180°three kind of angles.
: Fan Structure
: The boiler centrifugal fan is made by the impeller, housing, air inlet, driven set, regulating door and other parts.
: The impeller has 12 backward inclined plate blades of 16Mn material, which are welded in the arc cone impeller cover and in the middle of the plate-shaped disc, and are corrected by dynamic balance. Therefore, it runs smoothly, has high strength and wear resistance, and has a long service life,
