摘要

针对目前微流体混合器多需要外接动力源，且多数微混合器只能进行液体混合而不能输送液体的问题，提出将无阀压电泵引入微混合器领域，并研制了一种集混合与输送于一体的多级Y型流管无阀压电泵。首先，提出了多级Y型流管，进而设计了多级Y型流管无阀压电泵，并分析其工作原理；然后，对该无阀压电泵的流管流阻特性及泵流量进行理论分析；同时，利用有限元软件对多级Y型流管无阀压电泵进行了流场模拟，结果表明该压电泵具有单向传输作用。最后，制作了多级Y型流管无阀压电泵样机，并进行了泵流量与背压试验。试验结果显示：驱动电压峰峰值为100 V，频率为16 Hz时，流量达到最大，为16.2 ml/min；驱动电压峰峰值为100 V，频率为14 Hz时，输出背压最大，约为64 mm水柱。得到的试验数据证明了多级Y型流管无阀压电泵的有效性。(

Abstract

This paper researches how to improve the performance and applications of micromixers used in mixing micro-liquids

because most of the existing micromixers need external power sources

and can only mix fluids but can not transport them. A valveless piezoelectric pump with multistage Y-shape tubes which integrates both functions of mixing and transporting is developed to overcome above shortcomings. Firstly

a multistage Y-shape tube is proposed

then a valveless piezoelectric pump with multistage Y-shape tubes is designed and its working principle is analyzed. Furthermore

the flow resistance characteristics and the flow rate of the valveless piezoelectric pump are analyzed theoretically. Meanwhile

finite element software is employed in simulating the flow fields of the pump numerically. The results show that the piezoelectric pump has a function of one-way transmission. Finally

the valveless piezoelectric pump is fabricated

the relationships between flow rate and driving frequency

as well as that between back pressure and driving frequency are experimentally investigated. The experimental results show that the maximum flow rate is 16.2 mL/min under a peak-to-peak voltage of power supply in 100 V(16 Hz)

and the maximum back pressure is obout 64 mmH2O under a peak-to-peak voltage of power supply in 100 V (14 Hz). The obtained experimental results validate the feasibility of the valveless piezoelectric pump with multistage Y-shape tubes.
