Pump definition

General frame

The pump device is considered as a black-box, with Current and Voltage inputs on the electric side, and Head and Flowrate values at the hydraulic side (cf Pump model). Technical features of the motor-pump aggregate are not needed in detail.

In PVsyst, many Pump are associated with a power converter, which have to be included in the pump device definition. In these cases the input electrical variables are those of the converter.

All parameters related to a given Pump, as well as graphs of its behavior, are available in the Pump definition dialog which is composed of several definition sheets:

  • General data, which holds the pump identifiers, and main electrical and hydraulic characteristics,
  • Detailed parameters, specifies some additional electrical parameters, and the choice of a model according to the available operating data set.
  • Data curves tab(s) hold the definition of the operating data according to the model choice.
  • Current Thresholds tab asks for the definition of the starting current thresholds, in a graphic-assisted way.
  • Size and Technology allow for writing a technical description of the pump features, as a text without limitations.
  • Commercial data,
  • Graphs and Running Conditions, offers a set of curves for visualizing the model behavior, as well as a little tool intended to compute the pump operating state for any desired input or output variable.
