Abstract

This paper proposes, designs, manufactures and experimentally studies a wedge valve piezoelectric pump driven by a double displacement amplifier vibrator (DDAV). A novel wedge valve is designed, manufactured and analyzed, and the static performance of the wedge valve is tested. The test results show that it has less forward resistance and high reverse shutoff. The DDAV and pump body are designed, and the test experimental platform is built. Results indicate that the static opening pressure of the wedge valve is 0.27 kPa, and the reverse shutoff pressure can reach 200 kPa. When the driving voltage is 700 Vpp and the driving frequency is 425 Hz, the maximum flow rate is 491.2 ml min−1 and the maximum output pressure is 160 kPa.

低正向阻力高反向关断阀基压电泵的设计与研究

本文提出、设计、制造并实验研究了一种由双位移放大器振动器（DDAV）驱动的楔形阀压电泵。设计、制造和分析了一种新型的楔形阀，并对其静态性能进行了测试。试验结果表明，它具有较小的正向阻力和较高的反向关断能力。设计了DDAV和泵体，搭建了测试实验平台。结果表明，楔形阀的静态开启压力为0.27kPa，反向关闭压力可达200kPa。当驱动电压为700 Vpp，驱动频率为425 Hz时，最大流量为491.2 ml min−1，最大输出压力为160 kPa。
