Watering pump with turn-off
In times of drought, farmers want to water their fields. They often have a diesel aggregate in the meadow for this purpose, which feeds the well pump, This is used to automatically pull the sprayer through the meadow via a winder.
Diesel is expensive, so more and more farmers provide an electrical connection at the pump. Via a Delta variable speed drive, the pump is controlled and when the stroke is fully reeled in and the pressure drops, the installation stops automatically. With specially developed software, the installation does not watch the pressure at start-up, but perceives at the end that the pressure drops. The controller ensures that the start-up current of the pump is minimised, saving energy.
