摘要

根据电磁泵原理

着重对电磁泵中电磁场的设计方法进行了研究

获得了分体式电磁铁磁隙宽度和磁极结构对磁隙中磁感应强度B的影响规律。结果表明

磁感应强度B与铁芯横截面积S的平方根S、磁感应强度B的自然对数lnB与磁隙宽度δ以及与铁芯的中心线长度L0和铁芯横截面积S的平方根之比L0/S～（1/2）均成线性关系。利用数学回归分析的方法

推导出开口磁铁在饱和阶段磁隙间的磁感应强度B的经验计算公式。

Abstract

Based on the principle of electromagnetic pump

design of electromagnetic field in electromagnetic pump was emphatically conducted.Effects of gas width and magnetic pole in divided electromagnet on magnetic induction intensity（B）were investigated.The results reveal that B has a linear relationship with square root of section area of iron core

and lnB has a linear relationship with gas width as well as center line circumference via square root of section area.The empirical calculation formula on B in a magnetic air gap for an open magnet in the saturated state was induced by a mathematical regression method.
