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3046 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1067 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。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 3036 mL.When pumping liquid water,the asynchronous drive is used,the output performance is better,and the output flow rate reaches a maximum of 1067 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.
