Information

Model to demonstrate the usage of CentrifugalPump. See its documentation for further information on the model.

You may connect any of the input signal to the centrifugalPump for the corresponding pumpMode:

• pumpMode = pumpMode.flange enables a mechanical connector. Set flowResistance.initM_flow = state, flowResistance.m_flow_0 = 0 and eventually pump.phi(start=0, fixed=false) to avoid warnings or errors.
• pumpMode = pumpMode.flowControlled enables to set mass or volume flow rate by parameter or from input signal. Set flowResistance.initM_flow = none to avoid warnings or errors.
• pumpMode = pumpMode.pressureControlled enables to set outlet pressure, pressure ratio or pressure difference by parameter or from input signal. Set flowResistance.initM_flow = state, flowResistance.m_flow_0 = 0 to avoid warnings or errors.
• pumpMode = pumpMode.speedControlled enables to set angular velocity by parameter or from input signal. Set flowResistance.initM_flow = state, flowResistance.m_flow_0 = 0 to avoid warnings or errors.

setpointFromInput enables switching between setpoint by parameter or from input signal.

The centrifugal pump can be parameterized either with a measurements record or with a coefficient record. There are already measurements records and coefficient records for some examplary centrifugal pumps.
User specific pumps can be added by creating a new measurement record or by calculating the coefficient record using the example CalculateCoefficientsFromMeasurements.
Furthermore coefficient records are designed to enable the user to generate a reasonable pump curve by scaling, e.g. by applying similarity laws.
