Pump

Create Function

create_pump(net, from_junction, to_junction, std_type, name=None, index=None, in_service=True, type='pump', **kwargs)

Adds one pump in table net[“pump”].

Parameters:
  • net (pandapipesNet) – The net for which this pump should be created

  • from_junction (int) – ID of the junction on one side which the pump will be connected with

  • to_junction (int) – ID of the junction on the other side which the pump will be connected with

  • std_type (string, default None) – There are currently three different std_types. This std_types are P1, P2, P3. Each of them describes a specific pump behaviour setting volume flow and pressure in context.

  • name (str, default None) – A name tag for this pump

  • index (int, default None) – Force a specified ID if it is available. If None, the index one higher than the highest already existing index is selected.

  • in_service (bool, default True) – True if the pump is in service or False if it is out of service

  • type (str, default "pump") – Type variable to classify the pump

  • kwargs (dict) – Additional keyword arguments will be added as further columns to the net[“pump”] table

Returns:

index - The unique ID of the created element

Return type:

int

EXAMPLE:
>>> create_pump(net, 0, 1, std_type="P1")

Physical Model

The pump is used to lift the pressure of a fluid flowing therethrough. The pressure rise depends on pump specific technical product properties setting flowrate and pressure in correlation. Thus, by given flowrate the pressure lift can be calculated. There are three different standard types defined by default (P1, P2, P3). However, the user can easily extend the standard type list.

alternate Text

In pandapipes the pump is considered as branch element with zero length (pumps are considered ideal). Thus it behaves and is considered accordingly.
