Multistage Centrifugal Pump Test Rig.
Multistage Centrifugal Pump Test Rig
The setup is designed to study the performance of Multi stage centrifugal pumps.
Set
up consists of a multi stage centrifugal pump coupled with DC motor
& drive, supply tank, measuring tank & pipe fittings for closed
loop water circulation. There are 2 separate pumps connected to DC motor
and drive and can be connected in series and parallel to stimulate
different combinations. Pressure and Vacuum gauges are connected on
delivery and suction side of each pump for the purpose of measurement.
Swinging
Field Dynamometer arrangement for direct torque measurement using dial
type spring balance is made for individual pump. The flow rate of water
is measured using measuring tank and stop watch provided
