Abstract:In order to improve output flow rate and pressure and enlarge its self-priming performance, 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.
