Liquid metal lithium circuits are large installations used to study engineering problems such as MHD pressure drop and material compatibility in fusion reactors. This paper mainly introduces the design parameters, circuit structure, components and loops of the lithium circuit device built in the South Industries Institute of Nuclear Industry. This circuit consists of the main circuit of liquid metal flow area and argon gas system, vacuum system, oil cooling system, power supply and control system, data acquisition and processing system, safety and alarm system. The loop runs in two stages: the first stage uses Na-K alloy at room temperature to study the MHD pressure drop and the second stage uses lithium metal to work at 350-500 ° C to study the material compatibility. Hartmam parameters and interaction parameters that represent the characteristics of the loop are respectively 6343 and 12172, the maximum flow velocity of the liquid metal in the pipeline is 1.38m / s and the magnetic field strength is 2.0T.
