摘　　要：水压传动技术是直接以天然淡水或海水代替矿物油作为液压传动系统工作介质的一门新技术 ,具有清洁、环保、安全、廉价等突出优点 ,是目前流体传动与控制技术研究的主要热点之一。本文阐述了液压传动技术发展的历史进程 ,指出了水压传动必将代替油压传动 ,成为液压传动技术发展的主流 ,并从液压泵 /马达、阀、系统等方面全面论述了国内外水传动技术研究和发展的现状及其在核能、海洋、消防、水力喷射等方面的应用 ,指出了今后水压传动技术发展的关键是材料和设计。Water hydraulic transmission technology,with great advantages of cleanliness,environmental protection,safety,cheapness and so on,is a new technique which directly takes raw fresh water or seawater as hydraulic fluid in place of mineral oil,and is one of the main study interests of fluid power transmission & control technology at present. The historical development of hydraulics is expatiated and the inevitability is indicated that water hydraulics regains its prominence instead of oil hydraulics in the end. The research and development of water hydraulic transmission technology at home and abroad are completely introduced in hydraulic pump/motor,valve,system,and their applications are discussed in nuclear power,marine,fire-fighting and water-jetting. It is also indicated that the materials and designs are the key techniques of water hydraulics in future.
