摘要
为提高压电泵的输出性能,结合串并联结构压电泵的优点,提出一种四腔混联压电泵设计.在110 V,40～400 Hz范围的正弦交流电驱动下,对制作的试验样机进行气体介质、液体介质的输送性能试验.结果显示:压电泵输送空气时,压电振子的工作模式对输出性能的影响可忽略不计,最大输出流量可达3 046 mL/min.压电泵输送液体水时,采用异步驱动,输出性能更好,驱动频率为140 Hz时输出流量达到最大,为1 067 mL/min.试验结果为多腔体混联压电泵的实际应用提供一定参考.
Abstract
In order to improve the output performance of the piezoelectric pump,a four-chamber hybrid piezoelectric pump design was proposed by combining the advantages of piezoelectric pumps with series-parallel structure.Driven by sinusoidal alternating current(AC)in the range of 110 V,40～400 Hz,the fabricated test prototype was subjected to the conveying performance tests of gaseous medium and liquid medium.The results showed that:when pumping air,the piezoelectric vibrator working mode has negligible effect on the output performance,the maximum output flow rate can reach 3 036 mL.When pumping liquid water,the asynchronous drive is used,the output performance is better,and the output flow rate reaches a maximum of 1 067 mL when the driving frequency is 140 Hz.The test results provide some reference for the practical application of multi-chamber mixed-connection piezoelectric pumps.
