Series and Parallel Pumps
FM-100.09
- Start-up of a pump, analysis and study of different aspects to consider.
- Priming pump.
- Checking the sense of rotation.
- Over current produced in the engine.
- Study and obtain the characteristic curves of a pump.
− Height – flow
− Hydraulic power – flow
− Torque – flow
− Mechanical efficiency – flow
− Mechanical power – flow
− Efficiency of the engine – flow
−Electric power – flow
− Total efficiency – flow
- 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.
