Photovoltaic Water Pumping System

Working principle and advantages of solar pumping systemSolar pumping system is an innovative technology that converts solar energy into mechanical energy to achieve pumping function. It has great potential in solving water shortage and energy crisis, and provides strong support for sustainable development.   Working principleThe core components of solar pumping system include solar collector, heat exchanger, working fluid circulation system and water pump. Solar collector is responsible for absorbing heat from sunlight and heating working fluid (usually water or other heat transfer medium). The heated working fluid passes through the heat exchanger and transfers heat to another working fluid to generate steam. Steam drives the turbine to rotate, and the turbine drives the water pump through the transmission device to pump water from low to high. The whole process utilizes the thermal energy of solar energy and realizes energy conversion and transfer through the heat engine cycle.…
