Key Components of Marine Centrifugal Fan
Impeller
The heart of the centrifugal fan is the impeller, a rotating disk with curved blades. These blades are designed to capture air at the center of the impeller and impart a radially outward motion to the air.
Housing or Casing
The impeller is housed in a casing or housing with a gradually expanding spiral shape. As the air moves radially outward, it gains velocity and pressure due to the increasing volume in the casing.
Inlet and Outlet
The centrifugal fan has an inlet that draws air into the impeller and an outlet where the pressurized air is discharged.
How the Marine Centrifugal Fan Housing Affects Pressure and Airflow
The marine centrifugal fan housing directs the air moved by the impeller; it surrounds the impeller and forms a chamber that contains the impeller and the air being moved.
The housing is designed to guide the air as it flows through the marine centrifugal fan and push it out – via the discharge point – in a specific direction. This helps to increase the pressure and velocity of the air as it exits the marine centrifugal fan. The housing prevents air leaks and protects the impeller and other internal components from external elements.
The shape and size of the housing are also important factors that determine the performance of the marine centrifugal fan and its ability to move air effectively.
The typical clearance between blade tips and housing is 0.25% of the impeller’s diameter. Reducing this clearance will increase peak marine centrifugal fan pressure (and vice versa). Housings can also include features such as inlet and outlet cones, vanes and scroll sections to further shape and guide the airflow.
A marine centrifugal fan housing typically looks like an ammonite shell without the spiral. This is called a volute casing; it is a curved funnel that increases in area as it approaches the discharge port.
The ‘ammonite’-style shape of a volute casing uses an outlet flow design. The air leaving the impeller has kinetic energy proportional to its velocity pressure – resulting in greater efficiency.
This is because the kinetic energy of the air helps to maintain its momentum as it flows through the marine centrifugal fan, reducing losses due to friction and turbulence. Additionally, the ammonite-style shape of the volute casing helps to smooth out the flow of the air and further reduce these losses – resulting in a more efficient marine centrifugal fan overall.
