Design Considerations and Applications For Industrial Blowers

Industrial blowers are mechanical devices that can move gas or air and are used in many industrial processes as well as applications that require improved gas or airflow. Increased airflow is achieved by the rotation of a fan wheel with multiple fan blades. This fan wheel accelerates the air entering the blower housing and pushes it out at the exit of the housing, thus supplying air to the application. The fan wheel is usually rotated by an electric motor or turbine. There are two types of blowers, centrifugal and axial, which are classified based on the direction of airflow. Depending on your application, there are various blower design options available, and the blower should be selected in such a way that it provides long and efficient service.

Design aspects

There are many factors to consider when designing an industrial blower, with the primary focus being on the application for which the blower is being selected. Application specific flow and pressure requirements are the primary factors considered for blower design. Another factor to consider is the airflow characteristics of the application, such as whether the blower will operate in an abrasive environment. A distinctive factor in the design of centrifugal machines is to operate the units with a narrow range of operating pressures. When designing the blower, it is important to ensure that eddies and turbulence are also prevented in the blower housing, resulting in minimal blade wear. Larger and faster fans increase the force on rotating structures; Consequently, the blower must also be designed in such a way that impulsive resonant frequencies and high stresses are eliminated.

Blower selection and installation

Generally, the selection of blower is based on its longevity, performance and efficiency. However, the noise characteristics of the blower are also considered, especially in cases where blowers are used in HVAC systems. When installing the blower, it is important to install it on a rigid base to avoid resonance.

Blade selection

There are various types and configurations of blades available for industrial blowers, be it centrifugal or axial fans.

The primary blade configurations for centrifugal blowers are radial, forward inclined, and backward inclined. All of these blade configurations have pros and cons and should be chosen based on the application.

Radial fans provide high pressure, high speed and low noise airflow, making them ideal for pneumatic conveying systems as well as vacuum cleaners. In addition, its low sensitivity to solids also makes it particularly suitable for applications with particulate-laden gas streams. Forward column fans are generally available with both flat and curved blades. These fans are ideal for low pressure, high volume applications. On the other hand, backward inclined fans offer better efficiency and are better disposed to handle air flow with moderate particulate loading. They are particularly ideal for applications requiring high pressure and medium flow.

Axial fans are available with variable pitch blades. In this type of fan, the pitch of the blades is changed periodically according to the pressure and volume requirements of the application. Another variation of this type is “on-the-fly” variable pitch, in which the pitch of the blades can be changed while the rotor is spinning. This option gives axial fans a versatility that makes them ideal for a wide spectrum of airflow applications.

flow control

In certain applications, flow control will also be required. In such cases, a method of flow control must be selected. The two primary methods of controlling flow are speed differentials and industrial dampers. The speed difference is achieved by controlling the speed of the driver. For this, use an adjustable frequency AC controller, a hydraulic variable speed drive unit, as well as a DC motor and drive. Industrial dampers, on the other hand, control flow by restricting airflow. A variety of dampers are available for use with industrial blowers, including radial inlet dampers, louvered inlet box dampers, and discharge dampers.
