Different to the traditionally defined valved piezoelectric (PZT) pump and valveless PZT pump, two groups of pumps with built-in compliant structures—with distances between free ends 0.2 mm (Group A) 0 B)—were designed, fabricated, experimentally tested. This type mainly contains a chamber 12 in diameter 1.1 height, vibrator, pairs structures arranged on flowing channel. The flow-resistance differences these were theoretically verified. relationships amplitude, applied voltage frequency...
Imitating the structure of venous valve and its characteristics passive opening closing with changes in heart pressure, a piezoelectric pump flexible valves (PPFV) was designed. Firstly, working principle PPFV were introduced. Then, valve, main functional component pump, analyzed theoretically. Finally, an experimental prototype manufactured performance tested. The research proves that can achieve smooth transition between valved valveless by only changing driving signal (PZT) vibrator....
Studies have shown that the valveless piezoelectric pump with streamline flow tubes (VPPSFTs) can increase rate while reducing vortex, which has a broad application prospect and conforms to huge potential demand in fields of medical treatment, sanitation, health care. The runner VPPSFT was designed as two segments smooth transition between hyperbola segment arc segment. However, effect radius on performance is not clear. Therefore, three groups different curvature radii were this study,...
Abstract In order to promote the application of raindrop-shaped flow tube valveless piezoelectric pump (RSFTV PZT pump), basing on existing research, RSFTV was simulated by computer. Firstly, existence resistance proved simulation FLUENT. Then, dynamic mesh analysis carried out simulate pumping rate at different driving frequencies. Lastly, results were compared with experimental results, which shows that tendency and value obtained are basically consistent experiment. The would be helpful...
