【摘要】 磁性流体行波泵作为磁性流体的典型应用已经得到了普遍的关注。行波磁场的产生、泵体结构的设计、磁性流体的动力学特性等均为磁性流体行波泵研究的关键技术。根据行波磁场产生的形式设计了磁性流体直线行波泵。行波磁场作用下的磁性流体流量与磁场的强度有直接关系:磁场越强,其流量越大。随着磁场强度的不断增加,由于磁场对磁性流体粘度的影响其流量的变化率在减小。磁性流体的饱和磁化强度越大,其流量也越大。更多还原

【Abstract】 The magnetic fluid traveling wave pump as the representative application of magnetic fluid produces the phenomenon of flowing.The key techniques of the research of the magnetic fluid traveling wave pump are the production of traveling wave magnetic field,the design of pump structure,and the dynamics characteristics of magnetic fluid,and so on.According to the form of the production of traveling wave magnetic field,the line magnetic fluid traveling wave pump has been designed.Under the effect of traveling wave magnetic field,the magnetic fluid flux has a direct relationship with the magnetic field.The bigger is the magnetic field,the more is the flux.The flux rate of the magnetic fluid will reduce with the increase of the magnetic field because of the increase of the viscosity of the magnetic fluid.The bigger is the saturation magnetization of the magnetic fluid, the more is the flux.更多还原
