Product Code : SCL-CELE-14187
Overview
The Axial Fan Test Apparatus is
designed to study the performance characteristics and operating behavior of
axial (propeller-type) fans. The unit enables students to investigate the
relationships between flow rate, pressure difference, rotational
speed, and efficiency, as well as the overall performance curve of
the fan under various operating conditions.
In an axial fan, air is drawn axially
through the intake section and discharged axially through the fan rotor.
The apparatus features an electronically commutated drive motor with variable
speed control, allowing smooth adjustment of airflow velocity. Both the intake
and delivery pipes are made from transparent material, providing
clear visualization of the flow and internal components.
The system incorporates guide vanes and
a flow straightener in the intake section to minimize turbulence and
ensure accurate measurement, even at low speeds. A throttle valve is
provided at the delivery end to control the airflow rate. The apparatus is
equipped with microprocessor-based measuring instrumentation to monitor
and display parameters such as differential pressure, temperature, flow
rate, power consumption, and efficiency.
For advanced laboratory applications, the unit
can be supplied with computer-based data acquisition and PID control
software, allowing real-time monitoring, process control, data storage, and
graphical visualization of results.
