| 摘 要： | １引言由于多相泵输送的是气液两相混合介质，而且其中气或液的含量往往高于常规泵或压缩机的工作范围，所以多相泵应兼备压缩机和泵的性能，这使多相泵的设计成为一个难点。到目前为止，国外已开发研制出的多相泵主要有容积式和叶片式［１］，业已进入现场试验和工业化应用阶段，但离形成完整的设计方法还有一定距离，国内这方面的工作则刚刚起步。所以目前对于多相泵尚没有成熟的设计方法，还不能象清水泵那样，按给定的流量、扬程、转速等参数进行可靠的设计。在多相泵的设计中，人们关心的主要问题是：泵型选择、总体设计方案的确定、效…

| Abstract: | Both twin--screw and helico-axial pumps were operated successfully and consideredavailable for onshore and offshoye development. The multiphase pump can reach to itshighest efficiency only at the design point, which is far lower than ordinary pump. So howto design the multiphase pump and how to increase the efficiency of the pump are the focusof researchers' attention. This paper presents some discussions on the multiphase pump andefficiency of pump, on the basic of this, a conceptual design method--named as segmentalincompressible method and variable compression efficiency are given. |
