recordStratos25slash1to6
Pump data for a Wilo Stratos 25/1-6 pump
Extends from Generic (Generic data record for movers).
Information
Data from http://productfinder.wilo.com/en/COM/product/00000018000028040002003a/fc_product_datasheet
The nominal rpm is arbitrarily chosen as the rpm of the pump curve in the data sheet that has the highest rpm, without being limited by the maximum power limitation (see dotted curve on figure below). Pump curves (H(m_flow) and P(m_flow)) from the data sheets are digitized using web plot digitizer.
Limitations:
- The pump curve cap at high rpm that can be seen is not enforced by the model.
- The pump curve may be altered slightly to guarantee that dp/dm<0
The figure below illustrates a digitized pump curve.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | havePressureCurve (from Generic) | sum(pressure.V_flow) > Modelica.Constants.eps and sum(pressure.dp) > Modelica.Constants.eps | = true, if default record values are being used |
| Pressure curve | |||
| IBPSA.Fluid.Movers.BaseClasses.Characteristics.flowParameters | pressure (from Generic) | Volume flow rate vs. total pressure rise | |
| Power computation | |||
| Boolean | use_powerCharacteristic (from Generic) | false | Use power data instead of motor efficiency |
| IBPSA.Fluid.Movers.BaseClasses.Characteristics.efficiencyParameters | hydraulicEfficiency (from Generic) | Hydraulic efficiency (used if use_powerCharacteristic=false) | |
| IBPSA.Fluid.Movers.BaseClasses.Characteristics.efficiencyParameters | motorEfficiency (from Generic) | Electric motor efficiency (used if use_powerCharacteristic=false) | |
| BaseClasses.Characteristics.powerParameters | power (from Generic) | Volume flow rate vs. electrical power consumption (used if use_powerCharacteristic=true) | |
| Motor heat rejection | |||
| Boolean | motorCooledByFluid (from Generic) | true | If true, then motor heat is added to fluid stream |
| Normalized speeds (used in model, default values assigned from speeds in rpm) | |||
| Real | speed_nominal (from Generic) | 1 | Nominal rotational speed for flow characteristic |
| Real | constantSpeed (from Generic) | constantSpeed_rpm/speed_rpm_nominal | Normalized speed set point, used if inputType = IBPSA.Fluid.Types.InputType.Constant |
