摘要(Abstract):

根据往复泵的循环指示图建立了计算多相流往复泵有效功率的新方法。当往复泵所输送的流体为气液两相混合液时 ,往复泵的有效功率由两部分组成 :一是对液体做功所消耗的功率 ;二是对气体作功所消耗的功率
A new calculating formula of the effective power of the reciprocating pump of multiphase flow is set up by the cyclic indicating figure of the pump. When the fluid which is transported by the pump is the mixture of gas and liquid, the effective power is consists of two parts, one is the power consumed by compressing the liquid, and another is the power consumed by compressing the gas.
