Centrifugal pump
Thread Content
When a centrifugal pump is connected to piping, what determines the flow rate?
Rotational speed, pump inlet pressure, outlet valve opening. There are still obstacles regarding the details,,,,, For reference.
The liquid reaches an equilibrium state under the combined effect of the pump’s power and the resistance of the pipeline fittings
The pump’s characteristic curve determines the points at which the pump can operate, while the piping system determines which of these points the pump will actually operate at
It is determined by both the performance of the pump itself and the system resistance. The way the pump is connected to the piping, valves (flow control valves, check valves, etc.), filters, and the layout of the piping (such as elbows, the length of the straight sections in the pump’s inlet and outlet pipes, etc.) are all factors that contribute to the system’s resistance.
