摘　　要：重点总结了射流泵的基本特点、结构与工作原理,从设计理论、内部流动和基本应用三个方面详细论述了射流泵的发展现状。射流泵作为一种流体输送机械及混合反应设备,本身没有运动部件,结构特殊、工作可靠,将其与其他工作泵组合使用,可提高整个装置的吸程,改善汽蚀性能,因而广泛应用于农业、水利、交通运输和环境保护等国民经济的各部门。在归纳现有发展水平的基础上,对射流泵未来发展的趋势和方向做了深入剖析,为今后研究与设计提供了良好的理论基础。The jet pump＇s basic characteristic, structure and working principle are outlined. The development status of the jet pump including the design theory, internal flow and basic applications are discussed. As one of the liquid transportation machines and mixing reaction equipments, jet pump has no moving parts. Jet pump has special structure and works reliablely. It will enhance the device suction and improve cavitation characteristics if jet pump works with other pumps. The pumps are widely used in agriculture, water conservancy, traffic and environmental protection. The development tendency of jet pumps are also predicted .
