FL 03.1 – Series and Parallel Pumps
With this equipment you can practice much of the operations, start-up, operation and necessary regulations in a pump installation.
One of the pumps is controlled by a frecuency variable, which allows varying the speed of rotation. Likewise, this pump has a measurement system of mechanical torque.
The flow rate is measured by an electronic flow meter.
In addition, you can make an study of the characteristics of a pump, working individually and in groups, in series or in parallel, performing a wide range of practices and experiences.
- Start-up of a pump, analysis and study of different aspects to consider.
- Priming pump.
- Checking the sense of rotation.
- Overcurrent produced in the engine.
- Study and obtain the characteristic curves of a pump.
- Height – flow (H-Q).
- Hydraulic power – flow (P-Q).
- Torque – flow (M-Q).
- Mechanical efficiency – flow (m-Q).
- Mechanical power – flow (Pm – Q).
- Efficiency of the engine – flow (e-Q).
- Electric power – flow (Pe-Q).
- Total efficiency – flow (-Q).
- Study of cavitation, and obtaining the N.P.S.H. Curve required-flow.
- Study of the different forms of regulating a pump. Checking similarity laws.
- Variation of the rotational speed. Obtaining the new characteristic curves.
- Changing the operating point by varying the pumping installation.
- Manoeuvred of the discharge valve.
- Analysis of the same and different pumps working in group.
- Characteristic curves operating in serie.
