摘　　要：针对Y型单入-单出水流道无阀压电泵的输送流量较小,设计了一种Y型双入-双出水流道无阀压电泵结构。根据压电振子的结构尺寸、坐标及力学模型,对压电振子中心振幅与理论容积变化量进行分析。对Y型双入-双出水流道无阀压电泵流量进行理论计算。对两种压电泵进行流阻和流量的对比实验。结果表明:Y型双入-双出水流道无阀压电泵效率及流量均大于Y型单入-单出水流道无阀压电泵,实验结果与理论分析基本一致。To increase the quantity of flow for the piezoelectric pump with single input channel and single output channel of Y type, avalveless piezoelectric pump with double input channels and double output channels in Y type is presented. The design and workingprinciple of the pump are described. The central displacement of the actuator and the volume variation for the pump are analyzedaccording to the dimensions, coordinates and the mechanical model of the piezoelectric vibrator. The quantity of flow for the double Ychannel piezo-pump is calculated and contrast experiments for the single and double Y channel piezo-pumps are presented. Boththeoretic and experimental results have shown that the efficiency and flow rate of the double Y channel piezo-pump are greater than thoseof the Y single channel pump.
