DESCRIPTION:
The present Reciprocating Pump Test Rig is a self-contained unit operated on closed circuit basis containing a sump tank. The set-up consists of a Double acting, Single Cylinder Reciprocating Pump coupled with a swinging frame type DC Motor that permits direct torque measurement with the help of a spring balance. 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 RPM of Pump. Flow of water is measured by using measuring tank and stop watch. Vacuum gauge is fitted on suction line and Pressure gauge is fitted on delivery line to measure pressure.
EXPERIMENTATION:
To determine total head, overall efficiency, pump efficiency and volumetric efficiency of the reciprocating pump.
To find out torque with the help of swinging frame motor.
To plot Graph: Head vs Discharge Pump efficiency vs Discharge.
