Progress and developing trends in pump technology

泵作为一种典型的水力机械,在国民经济中扮演着重要的角色,其技术进展一直受到多个行业的关注。在各种应用需求的驱动以及材料、力学、信息和计算机等相关学科的带动下,泵理论和技术研究已取得巨大进展。人们对泵内流机理和运行特性的认识更为深入,数字化设计和信息化运维已得到广泛应用,泵产品已逐步具有生态友好和智能化特征。本文以2000年以来泵领域所取得的进展为重点,围绕旋涡泵、离心泵、混流泵、轴流泵和贯流泵等叶片式泵,从产品应用需求出发,针对泵的水动力学、设计技术、振动噪声、节能与运维技术等四个部分对技术进展进行综述,并对泵的发展趋势进行总结和展望。

As typical hydraulic machines, pumps play an important role in the national economy, and progress in pump technology attracts concerns from many industries. Driven by various application requirements on the modern pump, significant advances have been achieved in its theory and technology along with the rapid development in the related disciplines such as materials science, mechanics,informatics, and computer science. At present, its internal flow mechanisms and operating characteristics are understood more deeply, information technology is widely used in its design,operation and maintenance, and new pump products are gradually becoming eco-friendly and intelligent.This article focuses on the progress in the technology of various vane pumps achieved over the last two decades, including vortex pumps, centrifugal pumps, mixed flow pumps, axial flow pumps, and tubular pumps. Based on the requirements of product applications, this paper summarize the developing trends in the hydrodynamics, design technology, vibration and noise, and operation and maintenance technology of the modern pumps.
