摘要: 以免维修为特征的无可动部件的流体输送设备被称作免维修泵,是针对放射性、高温、剧毒、腐蚀性等危险性流体的输送难题而发展出的一类独特设备。与危险性流体直接接触的部分不存在机械可动部件(甚至电子元件),因此在使用过程中基本不需要维修和易于远程控制是该类设备的典型特征。对蒸汽喷射泵、气提泵、真空-柱塞流泵、二极管泵、反向流动转向泵、正向流动转向泵的原理、优缺点等进行了综述,尤其对综合性能优秀的反向流动转向泵的研究发展情况进行了重点介绍。

Abstract: Maintenance-free pumps (MFPs) without moving parts are designed and developed for pumping hazardous fluids that are radioactive, high-temperature, toxic or corrosive. MFPs satisfy two criteria: (1) They should be capable of remote operation and control, and (2) There should be no moving parts (even electronic components) directly in contact with the hazardous fluid. Operating principles and performance for steam-pumps, air-lift pumps, vacuum operated slug lift pumps, diode pumps, forward flow diverter pumps (FFD pumps) and reverse flow diverter pumps (RFD pumps) are reviewed. Due to its excellent performance, RFD pump is preferentially presented.

Key words: pump, maintenance-free, flow, fluid mechanics, valveless pump
