摘　　要：柱塞泵是液压系统中最核心、技术难度最大的组成部分,在航空航天中应用广泛。航天器和飞机性能的不断提高,对航空柱塞泵的压力、转速、效率、安全性和可靠性等技术及性能指标提出了更高的要求。柱塞泵中三大关键摩擦副的润滑和摩擦磨损性能又是柱塞泵性能和服役寿命的决定性因素。该文在回顾柱塞泵发展历程和设计方法的基础上,主要对柱塞泵关键摩擦副的润滑理论及试验进行了总结,着重对航空柱塞泵关键摩擦副表面改性和性能增强技术及方法进行分析和阐述。最后,对未来重点的研究方向进行了探讨和展望。The hydraulic piston pump is the core component of hydraulic systems in aeronautical and astronautical systems that also presents severe technical challenges. Advanced spacecraft and aircraft need even higher performance hydraulic piston pumps with increased pressures, speeds, efficiencies, safety, and reliability. The lubricating and frictional characteristics of the three key friction pairs are the critical factors affecting the performance and service life of hydraulic piston pumps. This article reviews the development history and design methods of aviation hydraulic piston pumps, summarizes the lubrication theories and experiments of the key friction pairs, and analyzes traditional and advanced surface modification methods which can reduce the friction coefficient and increase the wear resistance. Future research directions are also discussed.
