Variable Speed Centrifugal Pump Test - Application: Fluid Mechanics Lab Equipment

Specification:
VARIABLE SPEED CENTRIFUGAL PUMP TEST
Description:
The present Centrifugal Pump Test Rig is a self-contained unit operated on closed circuit basis containing a sump tank. The set-up consists of a Centrifugal pump coupled with a DC Motor.
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 Pump.
Flow of water is measured by using measuring tank and stopwatch.
Vacuum gauge is fitted on suction line and Pressure gauge is fitted on delivery line to measure the pressure.
Experimentation:
To determine total head, Pump Output, overall efficiency and pump efficiency of the centrifugal pump.
To plot Head vs Discharge, Pump efficiency vs Discharge, Pump Output vs Discharge.
