双腔薄膜阀压电泵的实验研究
Experimental research on double-chambered piezoelectric pump with membrane valves
【摘要】 实验研究了理论所不能解释的多种因素对双腔压电泵输出流量的影响规律。选取了一种高效的橡胶薄膜阀片,设计并制作了具有较高输出能力的双腔泵样机。120V交流信号下,双腔串联压电泵最佳工作频率为180Hz,输出参数为520ml/min、22kPa;双腔并联压电泵最佳工作频率为420Hz,输出参数为980ml/min、28kPa。通过实验确定了双腔压电泵的最佳腔体高度及双腔串联、并联压电泵压电片的最佳驱动方式。
【Abstract】 By experiment, many factors affecting the output ability of piezoelectric (PZT) pumps with double chambers are studied, which can’t be explained with theories. A high efficient rubber membrane valve was made, and double-chambered PZT pump with high output capability was designed and fabricated. When powered by AC 120 V, series-wound PZT pump has a output of 520 ml/min, 22 kPa, and parallel-connectioned PZT pump has a output of 980 ml/min、28 kPa. The optimal chamber height is found , and PZT diaphragm actuating ways in series-wound and parallel-connectioned pumps are proved.
