Application of Water Pumping System with Wind Power in Upland Tea Garden

Wind and solar energy should be utilized in farming system to save the energy.This study applied Profili and AutoCAD to design a wind-powered water pumping system for the upland tea garden.The system, which consisted an air compressor and an atmospheric pressure pump, was evaluated.The result showed that with 4.0m·s-1 wind a 2.1-m-diameter wind-powered water pumping system could pump water 30-m-high at a rate of 1.90kg·m-1.The power generated from 3 wind-powered water pump system was calculated to be 111 kWh, which could adequately supply the irrigation need of a 100-mu tea plantation.
