High-Efficiency 3D-Printed Three-Chamber Electromagnetic Peristaltic Micropump

This paper describes the design and characteristics of a three-chamber electromagnetic-driven peristaltic micropump based on 3D-printing technology. The micropump is composed of an NdFeB permanent magnet, a polydimethylsiloxane (PDMS) film, a 3D-printing pump body, bolts, electromagnets and a cantilever valve. Through simulation analysis and experiments using a single chamber and three chambers, valved and valveless, as well as different starting modes, the results were optimized. Finally, it is concluded that the performance of the three-chamber valved model is optimal under synchronous starting conditions. The measurement results show that the maximum output flow and back pressure of the 5 V, 0.3 A drive source are 2407.2 mu L/min and 1127 Pa, respectively. The maximum specific flow and back pressure of the micropump system are 534.9 mu L/min center dot W and 250.4 Pa/W, respectively.

This paper presents the design and characteristics of a three-chamber electromagnetic-driven peristaltic micropump based on 3D-printing technology. It includes an NdFeB permanent magnet, a polydimethylsiloxane (PDMS) film, a 3D-printing pump body, bolts, electromagnets, and a cantilever valve. Simulation analysis and experiments were conducted to optimize the results using single chamber and three chambers, with and without valves, and different starting modes. It is concluded that the performance of the three-chamber valved model is optimal under synchronous starting conditions. The maximum output flow and back pressure of the micropump system are 2407.2 μL/min and 1127 Pa, respectively, with a maximum specific flow and back pressure of 534.9 μL/min·W and 250.4 Pa/W, respectively.
