摘　　要：为了分析多级离心泵发展趋势,从专利数据的视角对国内外多级离心泵技术进行深入研究,剖析了国内外多级离心泵技术的专利申请趋势、申请国家分布、IPC分布、申请人分布以及专利被引频次,同时基于专利地图技术对国内外多级离心泵技术的主要研究方向进行分析.研究结果表明:全球多级离心泵技术的研究相对较少,主要集中在中国,正处于发展阶段,多级离心泵技术仍然是研发的热点,在未来依然会持续发展;国外多级离心泵技术的专利权人以企业和个人为主,国内则以科研单位居多,多级离心泵技术的研究成果并没有完全产品化和市场化;多级离心泵技术的专利主题主要集中在泵零部件的设计研究,其应用研究相对较少;多级离心泵的核心技术或基础研究主要分布在美国,被引频次最高的专利是US7407371B2.In order to obtain development trends of muhistage centrifugal pump, the technology in multistage centrifugal pumps was studied from the point of view of patent data, including patent application trend, patent distribution in various countries, IPC distribution, patentee distribution and patent citation frequency. At the same time, based on patent map technology, a few major research directions in multistage centrifugal pump technology were identified. It is shown that studies on multistage centrifugal pump technology are relatively little, mainly conducted in China, and in the developing stage, suggesting the multistage centrifugal pump technology is still a hot spot in research. Enterprises and individuals usually are patentees of multistage centrifugal pump technology abroad, but institutes and universities are the patentees in China, furthermore, these patents are not all commercialized. Themes of multistage centrifugal pump technology in patents are mainly focused on design of the pump parts, while those on its application are less. The core technology or basic study on multistage centrifugal pump is basically distributed in the United States, and the most frequently cited patent on multistage centrifugal pump is US7407371B2.
