Analysis and Calculation about Characteristic Parameters of Centrifugal Pump in Delivering Gas-Liquid-Solid Multiphase Flow

对离心泵输送固液、气液、气液固混合物时性能指标的计算问题进行了具体的研究 ,认为在气液固多相流的泵性能指标计算中必须考虑流型及各相的具体表现 ,扬程的计算要以“单位重量”为基础。论文重点进行了多相流动分析和扬程公式的推导 ,给出了泵使用和测试的相关计算方法和公式。参

This paper conducts some concepts and methods for calculating characteristic parameters of centrifugal pump when delivering solid liquid, gas liquid and gas liquid solid multiphase flow, emphasized on analyzing mixture flow and deducing head formula based on unit gravity. It proposes that flow models and each phases' character must be considered when counting multiphase pump's operation parameters. Those calculating methods and formulas will make contribution to using and testing pump. Refs 9.
