Experimental study results of the TsLIN-5/700 cylindrical linear induction pump

The results of an experimental investigation of a cylindiral induction pump TsLIN - 5/700 with the following operating characteristics are presented: pressure 5x105 Pa, current intensity 770 A, flow rate 700 m3/hr, power output 209 kw, efficiency 45%. The investigation has been carried out on a liquid-metal stand at a sodium temperature of 350 deg C. The operating and start-up characteristics of the pump different voltages are obtained. The thermal regime of the winding and the pump operation on parallel branches are investigated. The operability of the pump design, in which the thermal contact between the channel wall and the magnetic guide is ensured by the difference in the coefficients of linear expansion of the channel and the magnetic guide with the clamping rings have been confirmed. The pump operates steadily without any signs of cavitations at a low gauge pressure (up to 0.05x105 Pa) at a channel speed of 13 m/s. On the whole, the investigations confirm the possibility of constructing high-productivity and high-efficiency electromagnetic pumps capable of satisfying the operating requirements in the main loops of nuclear reactors
