Abstract: This article discusses the generation of pumping force in the. box-type pumping mixer, derives a two-parameter suction equation based on circular jet model, and analyses various factors affecting pumping mixers suction head. The parameters of the suction model are evaluated from experimental data of two systems, water-oil phase (Kerosene+ 5.0% Butanol) andaluminate liquor-oil phase, in a box-type pumping mixer-settler with a mixing volume of about 1.2 liters, and equipped with Rushton turbine and six-blade closed turbine as agitators.

摘要： 本文从理论上分析了混合澄清器泵吸力的成因和影响泵吸力的诸因素,利用圆形射流模型导出了二参数的泵吸力方程.在方箱泵吸式混合澄清器中,用六叶平桨和六叶闭式叶轮以水-有机相(磺化煤油+5%正丁醇)和碱性铝液-有机相为实验体系,测定了搅拌转速、搅拌器的安装高度、混合物相比及流体流量对泵吸力的关系.由这些实验数据求得泵吸力方程的参数.该模型与实验数据吻合较好.
