Axial Flow Fan Blade

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.

Axial flow fan blade.

The rapid design of a blade that pe. The basic principle of operation of the axial fan is that the direction of air flow is parallel to the rotor shaft. 1 22 m to 16 ft. An axial fan is a type of fan that causes gas to flow through it in an axial direction parallel to the shaft about which the blades rotate.

Axipal bzi the axipal bzi is a range of aerofoil axial flow fans with adjustable pitch angle blade. The present results show that. Diameter and has four blades. 1 22 m to six ft 1 84 m.

With a ball bearing motor and cupped fan blades these fans last longer and focus airflow better than economy fans. The fan is designed to produce a pressure difference and hence force to cause a flow through the fan. The flow is axial at entry and exit. 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.

The blades of the fans force air linearly to the shaft. In a typical axial fan the effective progress of the air is straight through the impeller at a constant distance from the axis. Abstractthe geometry design and machining of blades for axial flow fans are important issues because the twisted profile and flowfield of blades are complicated. The most common type for wet cooling towers is 28 ft diameter and has eight blades.

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 automatic featuring variable pitch standard chord sc blades with diameters from 4 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. Axial fans can have widely varied operating characteristics depending on blade width and shape number of blades and tip speed.
