An Experimental Study to Determine the Optimal Sizes for Ball-Valve Micropump Channel

Abstract:

The geometrical configurations of ball-valve micropumps have great influence on its efficiency. In particular, the ball valve channels have great influence on the efficiency of ball-valve micropumps because the prevention of backflow directly affects the performance of ball-valve micropumps.This study used water to investigate the optimal size of channels for piezoelectric ball-valve micropumps. The results show that the optimal angle for micro ball valve seats is 30°. The piezoelectric film vibrates rapidly and the back pressure in the water outlet channel is higher than it in the water inlet channel . This phenomenon indicates that channels are optimal sizes for a distance of 0 mm in the water inlet channel and 0.3mm in the water outlet channel.
