Abstract: The purpose of wind energy utilization is to reduce conventional energy consumption, to avoid environmental pollution, to reduce the running expenses, and to use as an auxiliary energy to benefit the people. This thesis, based on the analysis of the experiment of Model FDG-5 waterpumping windmill operating in Sheyang Saltern, Jiangsu Province, not only points out the social and economic benefits of using wind as energy in waterpumping, but also indicates that the wind will be the essential energy for wind pumping systems in salt making and prawn breeding industry. Considering the further commercial wide spread of wind pumping units utilization, a great deal of useful data are provided in this paper.
