DESCRIPTION :
The present Gear Pump Test Rig is a self-contained unit operated on closed circuit basis containing a sump tank. The set-up consists of a Gear Pump having a pair of meshed gears, coupled with a swinging frame type DC Motor which 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 the RPM of Pump. Flow of fluid 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, pump output, overall efficiency and pump efficiency.
To plot Graph:
- Head vs Discharge
- Pump efficiency vs Discharge.
UTILITIES REQUIRED :
- Electricity Supply: Single Phase, 220 V AC, 50 Hz, 5-15 amp combined socket with earth connection.
- Oil: SAE 20W 40(30 lt.)
- Drain required
- Floor Area Required: 1.5 x 0.75 m.
