Saini science industries manufacture of CENTRIFUGAL BLOWER TEST RIG. (variable speed)
This equipment comprises of a FD Centrifugal Blower coupled to a Motor. Three interchangeable impellers with forward, backward and radial vanes are provided with the test rig. A Pitot Tube is provided in the delivery line of blower for static & dynamic pressure. Power input to the DC Motor is varied by means of a Thyristor controlled DC Drive to vary the RPM of motor. A RPM Indicator with Proximity sensor indicates the RPM of Blower.
To study the effect of forward curved, back curved and radial curved impeller
To find out the discharge, head and efficiency of the Centrifugal Blower.
To plot the graph Efficiency vs Discharge
To plot the graph Discharge vs Head
