Title:
ELECTROMAGNETIC PUMP, QUENCH TANK, AND LIQUID METAL LOOP
Document Type and Number:
Japanese Patent JP2013207938
Kind Code:
A
Abstract:

To provide a compact electromagnetic pump by preventing a cavitation from being formed at the entrance of the electromagnetic pump.

An electromagnetic pump 100 includes, in a casing 1, a stainless steel-made outer cylinder 2, a stainless steel-made inner cylinder 3 arranged in the outer cylinder 2, and an electromagnetic coil 4 arranged around a periphery of the outer cylinder 2. The outer cylinder 2 is in a truncated cone shape on the whole, and has a large diameter on the entrance side and a small diameter on the exit side. Similarly, the inner cylinder 3 also has a large diameter on the entrance side and a small diameter on the exit side. A duct 5 is formed between the outer cylinder 2 and inner cylinder 3. The radial sectional area of the duct 5 is large on the entrance side and small on the exit side. In the electromagnetic pump 100, the duct 5 has the large sectional area on the entrance side, and so a flow velocity of liquid metal decreases on the entrance side to make pressure loss sufficiently small; and therefore, effects of totally preventing a cavitation from being formed at the electromagnetic pump 100 are obtained.
