![]() ![]() The invention resides in passing the return conductor for the current traversing the fiuid in the duct back through the gap in the iron circuit of the pump. ![]() This patent reiates to electromagnetic pumps for electricity-conducting fluids and, in particular, describes several modifications for a linear conduction type electromagnetic interaction pump. Techniques for fabricating components of pump are discussed. Three phase helical, electromagnetic induction pump for use as boiler feed pump in potassium Rankine-cycle power system is described. ![]() PMID:23201986Īdvanced high-temperature electromagnetic pump Given an actuating voltage of 3 V and a driving frequency of 15 Hz, the flow rate is found to be 13.2 mL/min under zero head pressure conditions. The experimental results show that a coil input current of 0.4 A generates an electromagnetic force of 47 mN and a diaphragm deflection of 108 μm. The resulting bi-directional deflection of the PDMS diaphragm causes the check-valve to open and close thereby creating a pumping effect. When an AC current is passed through the microcoil, an alternating electromagnetic force is established between the coil and the magnet. The pump comprises four major components, namely a lower glass plate containing a copper microcoil, a middle PMMA plate incorporating a PDMS diaphragm with a surface-mounted magnet, upper PMMA channel plates, and a ball-type check valve located at the channel inlet. This study presents an electromagnetically-actuated reciprocating pump for high-flow-rate microfluidic applications.
