The Structure of Wheel Check Valve Influence on Air Block Phenomenon of Piezoelectric Micro-Pump

To improve the stability and reliability of the piezoelectric micro-pump, the cause of air block phenomenon is analyzed on the structure of wheel check valve. During the movement of the bubble in the micro-channel, pressure drop occurs, the main factor which influences the bubble going through is op...
