Solar well pump and focussing mirror arrangement esp. for raising irrigation water from deep shafts

摘要

The solar pump is driven by solar power and pumps a liquid, e.g. water. A pressure connection for the liquid to be pumped has a feed line for the input pressure and a delivery line for ejection of the liquid delivered by the input pressure. A pressure generator consisting of a vessel (KG) heated by sunlight has a pressure outlet for blowing in the delivered liquid. A mirror system focuses the sunlight which heats the pressure generator. The pressure for blowing in the liquid is a vapour pressure produced by the pressure generator.
