Preliminary Study on Piezoelectric Actuation Solution Proportioner

Abstract:

The conventional solution proportioner, which is costly and bulky with complex mechanical structure, cant meet the current requirements of the apparatus, such as miniaturization, high reliability and accuracy. Based on the piezoelectric actuation technique, this paper proposed and developed a solution proportioning technique of large dilution ratio. And on the basis of this technology we produced a physical prototype, in which piezoelectric vibrators are used as the main power units and control parts because piezoelectric vibrators are featured with low cost, compact volume, simple structure, non-pollution and others. The physical prototype can be used to dilute various sample solutions of various proportions for one or more times.
