【Abstract】 In combination with the hydro-piezoelectric drive,bionics and water-jet thrust technology,a novel piezoelectric water-jet thrust was introduced,and the core of the thrust—piezoelectric jet pump was studied.The design,principal,process and performance of the pump jet were presented,and a prototype pump was designed and manufactured in the laboratory.Through a series of experiments and tests,It is concluded that the piezoelectric pump jet is characterized by stable performance and bucky volume of liquid flow,the optimization frequency is 1250 Hz.With the sine wave signal actuated, the maximum liquid flow rate of the pump jet is 714 ml/min when driving voltage is 190 V.更多还原
