Title: ELECTROMAGNETIC PUMP, QUENCH TANK AND LIQUID METAL LOOP
Abstract:
An electromagnetic pump (100) includes in a housing (1), a stainless steel outer cylinder (2), a stainless steel inner cylinder (3) arranged inside the outer cylinder (2), and an electromagnetic coil (4) arranged around the outer cylinder (2). The outer cylinder (2) is formed into a frustum shape as a whole with a large-diameter entrance and a small-diameter exit. Similarly, the inner cylinder (3) has a large-diameter entrance and a small-diameter exit. A duct (5) is formed between the outer cylinder (2) and the inner cylinder (3). The duct (5) has a large radial cross-sectional area at the entrance and a small radial cross-sectional area at the exit. The electromagnetic pump (100) has a large cross-sectional area for the entrance of the duct (5), and thus the flow rate of liquid metal decreases at the entrance, thereby sufficiently minimizing the pressure loss, which overall works to prevent the generation of cavitation in the electromagnetic pump (100). Accordingly, the height of loop piping can be reduced and there is no need to secure the height of the loop piping depending on the circumstances, and thus the device can be made compact.
