ZHAO Ming-li, HUANG Qin, ZHANG Wei, LI Xin-xin. Investigation on design method of single chamber piezoelectric pump with cantilever valve[J]. Editorial Office of Optics and Precision Engineering, 2006,14(4): 607-611DOI:
the cantilever valve piezoelectic pump was comprehensively analyzed
and its dynamic model was established. After analysis of the interactions between hydro-mass
output pressure
system damp and working frequency
it is concluded that the decrease of chamber height will enhance the working frequency and stabilization. Then the vibrator structure parameters were confirmed through computing the influence law between vibrator structure parameter and amount of deformation. The conclusions show that the best thickness ratio is from 0.45 to 0.55 and the best diameter ratio is 0.8 to 0.9 between piezoelectric ceramic layer and the metal plate layer
respectively. The influence of the output form on the output ability also be considered
the result shows that axial output is in favor of the enhamement the output ability of the pump.
