【摘要】 本文研究了与人流量直流电磁泵研制设计有关的儿项关键技术，并进行了双联直流电磁泵的可行性模拟实验研究。通过对不同聚磁结构参数电磁铁I-B关系的系列实验和对实验数据的整理与分析，得出了有聚磁效应的分体式开口电磁铁磁隙磁感应强度计算的经验公式。应用流体力学相关理论，结合电磁泵结构，建立了适合于电磁泵流量计算的简易方法。利用水银为工作介质的双联电磁泵，通过对双联电磁铁不同接法的实验研究，找到最佳激磁线圈接线方法；通过对不同流槽结构的静压头与工作参数关系实验，研究得出一种高效率的新型流槽结构——十字型流槽结构；通过对单泵、双泵的泵高和流量实验，得山了在同等工作条件下，双泵流量大约为单泵的1.6倍的结论，从而证明了采用双联泵的方法来提高直流电磁泵的方法是切实可行的。以上研究结果为大流量直流电磁泵的结构设计提供了有益的参考。更多还原

【Abstract】 In this paper, several key technique related to the exploitation and design of the direct current electromagnetic pump with great flux are studied; In order to prove the feasibility of the direct current electromagnetic pump with great flux, the simulative experiment are proceeded. Based on the I-B relation experiments of the different magnetism-collected structure parameter electromagnets and the analysis on the experimental data, a experienced formula is obtained, which can calculate the intensity of magnetization in magnetic gap of separate electromagnet with the magnetism-collected structure. Applying the theory on hydrodynamics and combining the structure of the pump, the method of calculating the flux is found, using the simulating dual pump which mercury serve as the working medium, by the experiment on the electromagnet used in the dual pump, the optimum method of the coil connection is gained; by the experiment on the relation the static pressure and the working parameter in different groove structure, a high-efficiency groove structure named as " + " shape are devised; by comparing the static pressure and flux between single pump and dual pump, the conclusion that the flux of dual pump is about 1. 6 times as much as the flux of single pump is educed, and prove it practical that the dual pump is adopted to increase the flux. The above results can afford a valuable reference for the structure design of the electromagnetic pump with great flux.更多还原
