In summary, it can be derived that, as the rotation angle increases, the magnetic field strength increases, and when the rotation angle of the electromagnet 10 is greater than 90 °, the magnetic field strength gradually decreases, so that the rotation angle of the electromagnet 10 is within the range of 0-90 ° during the rotation angle driving of the electromagnet 10;
In the process of changing the rotation angle, the magnetic field intensity changes, so that the magnetic entropy of the magnetic material in the magnetic field continuously changes, the magnetic moment in the magnetic material changes further towards an ordered state, and therefore, the external energy is absorbed, and the heat in the magnetic pump is further absorbed, so that the magnetic pump transports high-temperature media, the heat in the magnetic pump is higher, and the strength of the magnetic field can be enhanced by changing the angle of the electromagnet 10 when the current strength is increased to a rated current value, the heat dissipation capacity in the magnetic pump is further improved, and meanwhile, the removal efficiency of scale is greatly improved while the strength of the magnetic field is enhanced.
The modified iron functional alloy material carries particles with different energies, has excellent electronic transition capability and super-strong magnetic and electric absorption performance, so impurities in a medium transmitted by a magnetic pump are charged, become substances with polarity, change the electrostatic attraction effect of calcium ions and magnesium ions in the impurities, make the impurities difficult to adhere to the inner wall of the magnetic pump, and form scale substances on the inner wall of the magnetic pump, so that the speed of crystal scale generated by combining the impurities such as calcium ions and magnesium ions in the medium through ion attraction is reduced, and the electromagnet 10 has a certain magnetic field in the electrifying process, so that the impurities with charges in the magnetic pump can receive Lorentz force in the magnetic field, the movement direction of the impurities with charges and the movement track of the impurities can be changed, and the possibility that the impurities can generate crystal scale through ion attraction combination is further reduced.
In the invention, when the magnetic pump is required to radiate heat during operation, the electromagnet 10 is electrified, the current intensity is gradually increased to a rated current value, the electromagnet 10 generates a magnetic field, the intensity of the magnetic field is also increased along with the increase of the current intensity, the magnetic moment of the magnetic material is arranged from disorder to order along the direction of the magnetic field, the magnetic material absorbs the heat in the magnetic pump, after the electromagnet 10 is powered off, the intensity of the magnetic field is weakened to disappear, the magnetic material releases the heat absorbed before, the high-temperature heat exchanger 9 heats the heat emitted by the magnetic material into the cooling liquid in a heat transfer mode, the sealing channel 13 is used for conveying the cooling liquid to the low-temperature heat exchanger 11, the cooling liquid is cooled by the low-temperature heat exchanger 11, and the cooled cooling liquid is circulated to the high-temperature heat exchanger 9 again for heat transmission and radiation;
in the process of electrifying the electromagnet 10, a magnetic field appears and can generate Lorenter magnetic force with the impurities with charges in the magnetic pump, so that the movement direction of the impurities with charges and the movement track of the impurities with charges are changed;
When the magnetic pump transports high-temperature medium and the heat in the magnetic pump is high, and the current intensity is high and the temperature is raised to the rated current value, the temperature process in the magnetic pump is difficult to be rapidly discharged, so that the toothed ring 19 is driven to rotate by driving the toothed ring 19 to rotate the gear 18 meshed with the toothed ring 19, so that the electromagnet 10 positioned on the fixed seat 16 rotates within the range of 0-90 degrees to enhance the intensity of the magnetic field.
