Background
The electromagnetic pump directly converts electromagnetic energy into flowing kinetic energy, so that links of converting the electromagnetic pump into mechanical energy and converting the mechanical energy into fluid kinetic energy are eliminated, and the structure of the whole pump set is greatly simplified compared with that of a mechanical pump. Electromagnetic pumps are divided into two main categories according to the current feeding mode in liquid metal: conduction current electromagnetic pumps and induction current. The current conduction type electromagnetic pump is mainly classified into a direct current conduction type electromagnetic pump and a single-phase alternating current conduction type electromagnetic pump according to the form of a power supply. The induction current type electromagnetic pump is classified into three main forms, namely, a three-phase spiral induction electromagnetic pump, a three-phase planar induction electromagnetic pump, and a three-phase cylindrical induction electromagnetic pump, according to the difference in structure. When the three-phase cylindrical induction electromagnetic pump operates, three-phase alternating current is conducted on the winding coil to generate a magnetic field, the magnetic field induces current on the liquid metal in the pump channel, and the induced current and the magnetic field interact to generate magnetic field force, so that pressure difference is generated at an inlet and an outlet of the pump to push the liquid metal to move.
The winding coil is the main working part of the induction electromagnetic pump, but the insulating tape wound on the coil layer by layer is very sensitive to temperature. Because the high-temperature medium directly passes through the pump groove, and the electromagnetic coil is close to the pump groove, the temperature field of the electromagnetic coil is quite poor. Secondly, according to the working principle of the electromagnetic pump, the current density in the winding coil needs to be improved to maintain the working condition of large flow and large lift, which can cause the coil to generate a large amount of joule heat and cause adverse effects on the insulating layer of the coil. Therefore, the temperature field is the main limiting factor of the performance of the electromagnetic pump in the industry at present, and the temperature field control technology is one of the main research subjects in the field of the electromagnetic pump.
