摘要

为了提高压电泵的输出能力

采用压电双晶片进行驱动

设计了双腔并联被动截止阀压电泵

并加工了试验样机.对不同压电振子驱动方式(同步驱动或异步驱动)的双腔并联压电泵输出性能的影响规律进行了理论分析

分别以液体和气体为介质对样机进行了试验测试.测试结果表明:在110 V驱动电压下

工作频率小于400 Hz时

输送液体最大输出流量为1 330 mL/min

2个振子异步驱动泵的输出能力好于同步驱动; 输送气体最大输出流量为950 mL/min时

2个振子同步驱动和异步驱动泵的输出能力基本接近

从而确定了双腔并联压电泵输送流体时的最佳工作方式.

Abstract

To improve the output capability of piezoelectric pump

a dual-chamber piezoelectric pump in parallel connection with passive check valve was designed

and the experimental prototype driven by piezoelectric bimorph was processed. The output properties of dual-chamber piezoelectric pump in parallel connection was analyzed theoretically with liquid and gas as the media for different piezoelectric vibrator driven modes(synchronous drive and synchronous drive).The results show that the output capability of pump with two oscillators under asynchronous-driven gets better than that by synchronous drive for delivering liquid

and the maximum output flow was 1330 ml/min under 110 V drive voltage and within operating frequency range approaches less than 400 Hz. The output capability of pump with two oscillators under asynchronous drive gets close to synchronous-driven for delivering gas with maximum output flow 950 ml/min. Thus dual-chamber piezoelectric pump in parallel connection determines the optimum delivering fluid mode.
