Axial Flow Fan Blade

The most common type for wet cooling towers is 28 ft diameter and has eight blades.

Axial flow fan blade.

Abstractthe geometry design and machining of blades for axial flow fans are important issues because the twisted profile and flowfield of blades are complicated. Its low and medium pressure performance makes axipal bzi suitable for all air movement applications with clean dusty or humid air at temperatures from 20 c to 200 c. The class 10000 sd standard duty fan is a high efficiency axial flow fan designed for electric motor drive applications of diameters from four ft. The primary component of blade force on the air is directed axially from inlet to outlet and thus provides the pressure rise by a process that may be called direct blade action.

The basic principle of operation of the axial fan is that the direction of air flow is parallel to the rotor shaft. The flow is axial at entry and exit. 1 22 m to 16 ft. They are known to create a high flow rate and they are able to achieve a bigger volume of air flow.

The fan is designed to produce a pressure difference and hence force to cause a flow through the fan. The present results show that. High output pedestal fans generate at least 25 greater airflow than economy and premium fans. Diameter and has four blades.

Under design conditions the total pressure efficiency of the axial flow fan with the forward swept blade is the highest and the c type blade has slightly lower efficiency while the straight blade has the lowest efficiency. In a typical axial fan the effective progress of the air is straight through the impeller at a constant distance from the axis. The blades of the fans force air linearly to the shaft. 1 22 m to six ft 1 84 m.

The rapid design of a blade that pe. The most common type of fan for air cooled heat exchanger ache is less than 14 ft. With a ball bearing motor and cupped fan blades these fans last longer and focus airflow better than economy fans. The class 10000 automatic featuring variable pitch standard chord sc blades with diameters from 4 ft.
