ELECTROMAGNETIC PUMP

Structure and principle of electromagnetic pump system
Electromagnetic pump is a device that uses the interaction of magnetic field and current in conductive fluid to produce a pressure gradient under the action of electromagnetic force to promote fluid movement. In practice, it is mostly used for pumping liquid metal, so it is also called liquid metal electromagnetic pump. The role of the electromagnetic pump is to transfer liquid metal or other conductive liquids in a closed pipeline system. In this sense, the electromagnetic pump is similar to the equipment that provides the driving force with the rotating impeller, the difference is that the force is generated in a different way. The driving force can be explained by the left and right hand rule, that is, when the current flows through the conductor, an induced magnetic field will be generated by the action of the metal solution to generate the induced current, and the action of the induced current and the magnetic field will generate the electromagnetic thrust, which is the driving force for the movement of the metal solution, the force is not generated by the mechanical parts, and the non-contact with the metal solution is the most important characteristic of the electromagnetic pump.
Liquid metal electromagnetic pump market applications: recycled aluminum applications, quantitative casting, circulation mixing, special media transfer. The electromagnetic pump has no mechanical moving parts, simple structure, good sealing, reliable operation, and does not require shaft sealing, so it is used in the chemical industry and printing industry to transport some toxic heavy metals, such as mercury, lead, etc., for nuclear power and nuclear fusion devices to transport liquid metals (sodium or potassium, sodium potassium alloy, cyprinus lead) as heat carriers. It is more widely used for conveying molten non-ferrous metals in metallurgical casting production. The flow rate can reach 13000m3/ h, the pressure can reach 1.5 mpa, and the temperature can reach 1200°C.
