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

摘要：

　　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.
