摘要：Increasing the driving frequency of piezoelectric vibrator can resolve the bottleneck of low flow of the valve piezoelectric pump. However, the using of piezoelectric pump of traditional valve body all presents the hysteretic nature of valve; macroscopic performance is up-frequency to flow-sharply. This research is to settle the bottleneck mentioned above: firstly, through the sub-experiment on various parameters of plate valve of piezoelectric pump, the reasons for how valve body itself can influence "up-frequency to flow-sharply", which causes the hysteretic nature of valve, were discovered; then, E-shaped valve and piezoelectric pump with E-shaped valve (PPEV) were invented with purpose; finally, the efficiency of PPEV has been proved helpful to reduce hysteretic nature in experiment. Under the same conditions, the driving frequency of novel PPEV can be over 10 times higher and the flow rate can be also several times larger than traditional pumps. ? 2009 IEEE.
