通常是幼树或有限面积的果园使用灌溉,有时小到每分钟3或4加仑的水量,就可以满足需要。一般小功率电动泵,用于分散或距离较远的果园,因开销大难以实用。但如果使用自然风力作动力源就显得经济些。一部风车,装置一台常用的活塞型水泵,用来提水灌溉,但造价高,笨重,对风的适应性能也差。而风力提水泵是利用一架风力叶轮压缩机(由螺旅浆驱动的空气压缩机),提取地下水灌溉果园,虽然效率只有10%,但有取之不尽的风怍动力,而且结构 Irrigated trees, or fruit trees of limited area, are often small, sometimes as small as 3 or 4 gallons per minute, to meet their needs. General low-power electric pump, used to disperse or far away from the orchard, difficult to use due to large cost. However, if the use of natural wind power source is more economical. A windmill fitted with a commonly used piston pump is used to lift water for irrigation but at a high cost, bulky, and poor adaptability to the wind. The wind pump is the use of a wind turbine compressor (propeller driven by the air compressor), extraction of groundwater irrigation orchard, although only 10% efficiency, but inexhaustible wind power, and the structure
