Thinking about these needs, nowadays are available to buy solar pumping kits, allowing the withdraw of groundwater using renewable energy. We currently have a wide range of hydraulic pumps that work by solar or wind power. Among these, the centrifuges stand out because they now have a large part of the market. But with the scarce energy resources, pumping alternatives are being found, for example, a diaphragm pump, with low energy needs being perfectly coupled to a photovoltaic plate. With the growth of this area arise doubts in relation to the cost benefit and the risks of damages over the years. The data presented today show that a pump operating under the normal circumstances of a day loses to much efficiency due to climatic factors and it is not known which mechanical problems will result from this constant variation of the working frequency.Acesso AbertoBombas de deslocamento positivoBombas centrífugasEnergia solarmasterThesisCNPQ::ENGENHARIAS::ENGENHARIA MECANICA
