Abstract
Theoretical evaluations and modelling experiments demonstrated a rather high efficiency of electromagnetic induction pumps (EMIP) basing on permanent magnets, in which an alternating travelling magnetic field, inducing electromagnetic dragging forces in liquid metal, is generated by a system of rotating permanent magnets with alternating polarity. Basing on the gained experience at producing real pumps for pure Pb and eutectic alloy Pb--Bi, the evaluation of parameters of much more powerful pumps for mercury developing a head pressure over 5 bars and so providing flow rates over 10 L/s, had been carried out to show their reliability. These powerful pumps are supposed to be used in the proposed European Spallation neutron Source (ESS), in which mercury will be operated as a spallation target material and a cooling fluid at the same time.
