Product Description

TWO-STAGE AXIAL FAN

The was designed for measuring the fan characteristic curve of a two-stage axial fan. For this purpose 2 identical, speed regulated fans are fitted in a pipe. Connections for differential pressure measurement are fitted at appropriate points. Temperature and pressure are measured electronically before and after each stage. A 3-hole sensor with position measurement facilitates the measurement of speed distributions at impellers and guide wheels. In addition, speed and flow rate are measured. For comparison to the fans connected in series, the fans can also be operated separately. The fans each have individually adjustable blades and a guide wheel. All measured data is displayed on the unit and can be processed in other applications by means of the PC data acquisition.

Learning Objectives / Experiments

Determining the fan characteristic
Series configuration or individual operation of axial fans
Determining the energy balance
Determining the radial pressure and velocity
Distribution on rotor and guide vane system by means of a probe
Effect of the blade position
