摘要： 针对三棱柱阻流体无阀压电泵输出流量小的问题,基于箭头结构流阻小的特点设计了一种箭头型阻流体无阀压电泵,介绍了该泵的结构及工作原理。利用有限元软件模拟仿真了箭头型阻流体无阀压电泵的泵腔速度流线图,并将该泵与三棱柱阻流体无阀压电泵的阻力特性进行了对比分析。结果表明,箭头型阻流体无阀压电泵能单向运输流体,且其效率较三棱柱阻流体无阀压电泵提升了19.51 %。利用3D打印机制作了2种泵的样机,进行了流量和压差试验。试验结果表明,在300 V的驱动电压下,箭头型阻流体无阀压电泵的最大流量和压差分别为17.40 g/min和470 Pa,较三棱柱阻流体无阀压电泵分别提升了22.71 %和37.03 %。

Abstract: Aiming at the low output flow of the valveless piezoelectric pump with triangular prism bluff body,a valveless piezoelectric pump with arrow-shaped bluff body was designed based on the low flow resistance characteristic of the arrow structure,and the structure and working principle of this pump were introduced.The velocity streamline diagram of the valveless piezoelectric pump with arrow-shaped bluff body was simulated by finite element software,and the resistance characteristic of this pump was compared with that of the valveless piezoelectric pump with triangular prism bluff body.The results show that the valveless piezoelectric pump with arrow-shaped bluff body can transport fluids in one direction,and its efficiency is 19.51 % higher than that of the valveless piezoelectric pump with triangular prism bluff body.A 3D printer was used to produce pump prototypes,and the flow rate and pressure difference tests were carried out.The tests results show that under the driving voltage of 300 V,the maximum flow rate and pressure difference of the valveless piezoelectric pump with arrow-shaped bluff body are 17.40 g/min and 470 Pa,which are 22.71 % and 37.03 % higher than those of the valveless piezoelectric pump with triangular prism bluff body,respectively.
