Analysis and Design of Electromagnetic Pump

چکیده
Liquid metal loops are used for heat removal and for the study of certain magnetofluidic phenomenon like MHD (Magneto-Hydro Dynamic) effects. These loops operate at high temperatures and carry fluids that are invariably toxic in nature. To ensure the purity of fluid in a closed loop application, non-intrusive electromagnetic pumps are used. We have designed and analyzed a prototype electromagnetic pump to be used in mercury loop for carrying out various studies. This Electromagnetic pump is designed using permanent magnets which are mounted on the periphery of the rotor, driven by a DC motor. The liquid metal flows in a semi-circular duct surrounding the rotor. The paper brings out the qualitative and quantitative analyses of the pump as function of magnetization of the permanent magnets, the speed of rotation of the pump and magnet pitch. This electromagnetic pump has been developed and is running successfully in our lab at BARC.
