| 摘 要： | 为提高压电泵的输出流量和输出压力,增强自吸性能,采用四片压电振子构建两个工作腔体的新型压电泵结构,即双腔四振子压电泵.在对该新型压电泵进行结构设计的基础上,分析了其工作原理和工作特性,给出了输出流量和输出压力的计算方法,并加工制造了四振子压电泵样机.对四振子压电泵在单腔体双振子、双腔双振子和双腔四振子工作方式下进行了试验对比,结果表明,采用腔体串联能够提高压电泵的输出流量和输出压力,双腔四振子压电泵在驱动电压为150 V AC,频率为120 Hz时,最大输出流量为1160 mL/min,而双腔双振子最大输出流量为650 mL/min（138 Hz）,单腔双振子最大输出流量为250 mL/min（160 Hz）;双腔四振子压电泵自吸高度可达到55 cm. |

| Abstract: | In order to improve output flow rate and pressure and enlarge its self-priming perfor-mance,a new piezoelectric pump with two chambers was structured by four actuators,which is so called dual-chamber piezoelectric pump with four actuators.The working principle and operating characteristics of the pump were analyzed,and calculation methods for the output flow rate and pressure were given.Varied pump prototypes were manufactured and tested under three modes of single-chamber with two actuators,two-chamber with two actuators and two-chamber with four actuators.The results show that the maximal output flow rate of dual-chamber piezoelectric pump with four actuators powered by drive voltage of 150 V AC and operating frequency of 120 Hz is 1 160 mL/min,and only 650 mL/min（138 Hz） by dual-chamber with two actuators and 250 mL/min（160 Hz） by single-chamber and two actuators.The self-priming height of dual-chamber piezoelectric pump with four actuators can reach 55 cm. |
| Keywords: | piezoelectric pump piezoelectric-driven dual-chamber with four actuators self-priming flow rate |
