摘　　要：为了提高压电泵的输出性能,根据鸭嘴结构形式设计了一种柔性鸭嘴阀压电泵。首先阐述了柔性鸭嘴阀压电泵的结构及工作原理,其次对柔性鸭嘴阀压电泵的输出流量和输出压力进行理论分析,最后制作了柔性鸭嘴阀压电泵样机,并研究了其流量变化规律以及进出口压力差的变化规律。实验结果表明,在220 V、45 Hz正弦交流电驱动下,柔性鸭嘴阀压电泵进出口最大压力差可达15.5 kPa;在220 V、55 Hz正弦交流电驱动下,柔性鸭嘴阀压电泵的最大流量为39 mL/min。结果验证了柔性鸭嘴阀压电泵具有良好的输送能力。In order to improve the output performance of the piezoelectric pump,a flexible duckbill valve piezoelectric pump is designed according to the duckbill structure form.Firstly,the structure and working principle of the flexible duckbill valve piezoelectric pump are described;secondly,the output flow rate and output pressure of the flexible duckbill valve piezoelectric pump are theoretically analyzed;finally,the flexible duckbill valve piezoelectric pump prototype is made,and the change rules of the flow rate as well as the difference between the inlet and outlet pressures are investigated.The experimental results show that the maximum pressure difference between the inlet and outlet of the flexible duckbill valve piezoelectric pump can be up to 15.5 kPa driven by 220 V,45 Hz sinusoidal alternating current;the maximum flow rate of the flexible duckbill valve piezoelectric pump is 39 mL/min driven by 220 V,55 Hz sinusoidal alternating current.The results verify that the flexible duckbill valve piezoelectric pump has good conveying capacity.
