复杂电渗泵系统的输液特征

基于对电渗泵中压强产生原理的讨论, 对新兴的复杂串、并联电渗泵系统的流体输液特征加以研究. 在多级串联电渗泵系统中, 可以通过增加电渗泵的级数或操作电压来提高泵系统产生的压强, 但是单一流路的输液能力有限. 而在多级并联电渗泵系统中, 输液量也可以通过增加电渗泵的级数或操作电压得到提高. 在这一体系中, 尽管输液量的叠加有利于其在更为广泛的领域中应用, 但是因Joule热产生的电场强度与电渗流速度线性关系的偏离也使得其线性范围变小, 不利于操作条件的控制.

Liquid Transfer Characteristics in Complex Electroosmotic Pump System

On the basis of the discussion for middle pressure-producing principle, the transfer characteristics for liquid in a new type of complex parallel, or series electroosmotic pump system was investigated. In a multi-series electroosmotic pump, the pressure of a pump can be elevated by increasing the progression of an electroosmotic pump or applied voltage. But it has disadvantage because of its limit in liquid transfer. In a multi parallel connection electroosmotic pump, the flux of a pump can also be elevated by increasing the progression of an electroosmotic pump or applied voltage. The system can be used in a wide range due to the fold of liquid flux. But it has disadvantage in controlling the operation condition because of its smaller linear range caused by Joule heat.
