| 摘 要： | 设计了输出流量最佳频率为50 Hz的压电泵。测定了压电泵的进出口布置方式、进出水管管径、密封圈布置方式、腔体高度对压电泵流量最佳频率的影响规律。所设计的压电泵可直接利用日常照明电驱动,可通过电阻分压的方法实现压电泵的流量调节。试验结果表明:以水为工作介质,该压电泵在通用的50 Hz、220 V正弦交流电压驱动下工作性能稳定;流量可达到600 mL/min;省去了特制电源,从而大大降低了成本,具有较好的应用前景。

| Abstract: | A piezoelectric pump working at optimal for flow rate frequency 50 Hz was developed.The influences of the arrangement and diameters of inlet and outlet,the O-ring layout,and the chamber height on the optimal for flow rate working frequency were studied experimentally.The developed piezoelectric pump can be driven directly by the utility electric power supply system and its flow rate can be adjusted by a resistor voltage divider.The test results show that the pump works steadily with water as working medium and 50 Hz,200 V power supply and the flow rate as high as 600 mL/min. The pump is characterized by simple structure and low cost becanse of no need of the special power source. |
