液体混合用双入口压电泵仿真分析与试验研究

his article put forward using multi-entrance piezoelectric pump in the liquid mixing areas,double-entrance piezoelectric pump are designed and theirs working principles are analyzed.Fluent is used to simulate liquid velocity and pressure distribution in cavity body of double-entrance piezoelectric pump.By testing intake account for pump output of double-entrance piezoelectric pump and test results show that: double-entrance piezoelectric pump can output a mixture of two liquids and the percentage of intake account for pump output of double-entrance piezoelectric pump can be controlled by regulating the driving frequency as a result of controling the characteristic of the mixing liquid.
