VОМ-24 FAN APPLICATION

The VOM-24 axial-flow fan is designed to ventilate tunnels and underground stations. The fan is installed on-site in a tunnel chamber and can be used in single-fan / dual-fan installations. The airflow is reversed by changing the rotation direction of the electric drive motor while simultaneously altering the setting angle of the straightener blades.

VOM-24 fan design and features

The VOM 24 fan consists of the following assemblies: a housing, a rotor, straightener unit (SA), a manifold, a spinner, a damper, and drive motor.

The fan housing has a horizontal connector, and its both halves are connected by wedges. The rotor bearing supports are bolted to the housing.

—
The rotation of the straightener blades is performed separately, manually.

—
The fan rotor consists of a shaft with an impeller mounted on it; it rotates by means of two spherical roller bearings.

—
The impeller blades are fixed by spring rings, which allows changing the fan characteristics smoothly.

–
The blades are installed to the desired angle between 15° and 45° through the hatches when the fan is stopped.

—
Rotation from the electric motor to the rotor can be transmitted directly through an elastic coupling or by means of a V-belt transmission.
