Series And Parallel Pump Test Bench With Torque And Speed Measurement
Teaching Objectives of
Series And Parallel Pump Test Bench With Torque And Speed Measurement
- Study of the pumps alone, in series and in parallel modes.
- Determination of the characteristic curves (suction and discharge).
- Study of the relation flow/pressure.
- Study of the influence of the suction height.
- Influence of the rotational speed on the flow.
- Measurement of the electric power absorbed by a pump.
- Measurement of the mechanical power absorbed by a pump.
- Calculation of the efficiency of a pump.
- Demonstration of the cavitation phenomenon.
