摘要

由于自吸性差、对气泡敏感等原因，单腔体压电泵在应用中受到限制，采用多腔体结构是提高压电泵性能的有效途径。通过分析腔体容积与压力变化过程得出：双腔体串联压电泵只能采用串联驱动方式而不能采用并联驱动方式，双腔体并联压电泵只能采用并联驱动方式而不能采用串联驱动方式。制作双腔并联、串联压电泵样机进行测试：串联压电泵在驱动电压200VAC，频率152Hz时，输出流量达到最大为1150ml/min，并联泵在驱动电压140VAC，频率220Hz时，输出流量达到最大为640ml/min；因此多腔泵采用腔体串联结构能提高压电泵的工作效率，提高泵的工作性能。

Abstract

Single chamber piezo-pump is limit applied in many fields because lack of self-priming and bubble-tolerant

it is an efficient way that adopt multi-chamber structure to enhance the performance of piezo-pump. The analysis result about changing process of volume and pressure of chamber shows that double-chamber serial piezo-pump only can be tandem driven

and double-chamber parallel piezo-pump only can be parallel driven respectively. The experiment results indicate that the maximum flow of double-chamber serial pump is 1150ml/min (sine wave voltage is of 200v

frequency is of 152Hz) and that of double-chamber parallel pump is 640ml/min (sine wave voltage is of 140v

frequency is of 220Hz)

and the efficiency and performance is enhanced as chamber in tandem structure.
