摘　　要：研究了双腔串联两阀压电泵与三阀压电泵的输出性能,分析了这两种泵的结构和工作原理,理论分析得出:三阀泵输出性能优于两阀泵。设计制作了两阀泵与三阀泵实验样机,并通过实验测试证明了理论分析的正确性。分别对两阀泵和三阀泵进口腔和出口腔独立工作时流量输出进行了实验测试,并把进口腔和出口腔独立工作时输出流量相加之和,与两腔一起交叉工作时进行了比较。实验测试表明:两阀泵和三阀泵样机在200 V交流驱动电压下,最大输出流量分别为972 ml/min和1 035 ml/min,最大输出压力分别为28.7 kPa和40 kPa,最大自吸高度分别为0.41 m和0.43 m水柱高。By analyzing the working principles and structures of double-valved and three-valved piezoelectric pumps with double series-wound chambers, it was proved that the output ability of three-valved pump is better than that of double-valved pump. To explain the theoretical analyis,the pump samples were designed and manufactued, several experiments had been done when inlet chamber and outlet chamber work respectively, and the sum of flowrates was compared with that produced by their double chambers working together alternately. Experimental results show that double-valved and three-valved piezoelectric pumps＂ maximal output flowrates are 972 ml/min and 1 035 ml/min, maximal output pressures are 28. 7 kPa and 40 kPa, and maximal self-suction heights are 0. 41 mH2O and 0.43 mH2O, respectively when they are powered by AC 200 V,which indicates that the results agree with the theory very well.
