Fabrication and Basic Characterization of a Piezoelectric Valveless Micro Jet Pump

Japanese Journal of Applied Physics, 2008
A piezoelectric-driven valveless micro jet pump with a novel channel structure has been designed and fabricated. The simple structure micro jet pump consists of a lead zirconate titanate (PZT) diaphragm and flow channels. The design of the flow channels focuses on a cross junction formed by the neck of the pump chamber and one outlet and two opposite ...

Simulation research on bearing lubricating micro-jet driven by piezoelectric ceramic

2017 8th International Conference on Mechanical and Intelligent Manufacturing Technologies (ICMIMT), 2017
In order to solve the problem of the lubrication failure of bearing in Control Moment Gyroscope, this paper designs a kind of bearing lubricating device based on piezoelectric micro-jet theory. The lubricating oil is ejected by the device and then act on the bearing depend on the pressure waves which generated by piezoelectric vibrator.

Phase-Resolved Visualization of Micro-Jet Formation in a Piezoelectric Vibrating-Mesh Atomizer Using Inter-Cycle Imaging

This study investigates the microscopic jet formation dynamics of a piezoelectric vibrating-mesh atomizer operating at 100.7 kHz. Because direct single-cycle imaging of such high-frequency micro-jetting is limited by the trade-off between camera frame rate, optical magnification and image quality, an inter-cycle imaging method (ICIM) is used to ...
