Reciprocating Pump Test Rig, technical teaching equipment for engineering

RECIPROCATING PUMP TEST RIG (VARIABLE SPEED)

 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 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 stop watch. Vacuum gauge is fitted on suction line and Pressure gauge is fitted on delivery line to measure the pressure. 

EXPERIMENTATION: 

• To determine total head, overall efficiency, pump efficiency and volumetric efficiency of the reciprocating pump.
•   To plot Graph: Head vs Discharge Pump efficiency vs Discharge.
