Contrast Of The Export Power Of Piezoelectric Pump Driven By Two Kinds Of Signal |
| |
| Abstract: | The power of piezoelectric pump, which was fixed in the cavity of sense organ and driven by two kinds of signal, was studied. The relationship of displacements and velocities of pump driven by square wave and sine wave signal were analyzed in theory. An experiment was designed to show export power of pump. The result of experiment were accorded well with the analysis. The result indicated that pump driven by square wave shows larger export power than the pump driven by sine wave. |
