4-68 low pressure centrifugal fan

Use of 4-68 centrifugal fan

The 4-68 type centrifugal fan is generally used for ventilation and ventilation of factories and large buildings. It can be used as input gas or output gas. The fan can transport air or other non-combustible, non-explosive, non-volatile, Gas that is harmless to the human body and non-corrosive to steel, and there must be no sticky substances in the gas, the dust and hard particles contained in it should not exceed 150mg / m3, and the gas temperature should not exceed 80 ℃.

Structural features of 4-68 centrifugal fan

№2.8 ~ 6A of 4-68 fan is mainly composed of the direct connection of the distribution motors such as the impeller, casing, and air inlet. №6.3 ~ 20 In addition to the above parts, there are transmission parts:

Impeller: Welded 12 arc-shaped wing-shaped blades between the arc-cone wheel cover and the flat wheel disk. They are all made of steel plate, and after static and dynamic balance correction and overspeed operation experiments, the air performance is good, the efficiency is high, and the operation is stable. .
