Abstract

The invention discloses a liquid metal electromagnetic pump which comprises a liquid flow pipeline (30) and an electromagnetic driving device, wherein the liquid flow pipeline (30) has a liquid flow inlet used for receiving inflow of liquid metal and a liquid flow outlet used for conveying the liquid metal outwards; the electromagnetic driving device is used for providing an electromagnetic force for driving the liquid metal to flow from the liquid flow inlet to the liquid flow outlet; the electromagnetic driving device comprises a shell (60) and an inner iron core (50); the shell (60) is arranged on the radial inner side of the liquid flow pipeline (30), and a vacuum cavity is formed in the shell (60); an annular flow channel which is communicated with the liquid flow inlet and the liquid flow outlet and is used for liquid metal to circulate is formed between the outer surface of the shell (60) and the inner surface of the liquid flow pipeline (30); and the inner iron core (50) is arranged in the vacuum cavity, and at least part of the outer surface of the inner iron core (50) is tightly attached to the radial inner surface of the shell (60). The liquid metal electromagnetic pump can solve the problem that the working stability of a liquid metal electromagnetic pump is poor in the prior art.

Description

technical field [0001] The invention relates to the technical field of electromagnetic pumps, in particular to a liquid metal electromagnetic pump. Background technique [0002] As an important liquid metal conveying equipment, the liquid metal electromagnetic pump has been widely used in the field of nuclear power because of its advantages of no medium contact, no moving parts, complete sealing, and easy maintenance. The medium temperature of electromagnetic pumps in reactor engineering nuclear safety application scenarios is generally high, and the reliability requirements are relatively strict. At present, the working stability of the liquid metal electromagnetic pump is not high, and it cannot meet the application requirements of nuclear safety level in reactor engineering. Contents of the invention [0003] The purpose of the invention is to improve the working stability of the liquid metal electromagnetic pump. [0004] To achieve the above object, the present inve...
