Q: Will the magnetic coupling of the magnetic pump naturally decay in its magnetic force during long-term operation? What are the main non media factors affecting it?

A: The magnetic coupling of a magnetic pump may indeed experience a slow decay of magnetic force over time, but it is not completely "natural decay" and is more related to specific operating conditions. Non media factors mainly include:

1. Long term high temperature effects: If the working environment temperature of magnetic steel is close to or slightly above its Curie point for a long time (such as neodymium iron boron magnetic steel at about 300 ℃), even if it has not reached the critical value, it will accelerate the disorder of magnetic domain arrangement, leading to slow loss of magnetism.
2. Alternating magnetic field loss: The speed difference between the motor side and the pump side magnetic rotor (even if the time difference is extremely small during normal operation) will generate an alternating magnetic field, which may cause eddy current loss inside the magnetic steel under long-term action, indirectly leading to magnetic performance degradation.
3. Mechanical vibration impact: When the pump body vibrates frequently or starts and stops frequently, the magnetic steel may have internal microcracks due to small displacements or collisions, which can damage the integrity of the magnetic circuit and weaken the overall magnetic force.
This attenuation is usually gradual and can be alleviated by selecting high-temperature resistant magnetic materials (such as samarium cobalt magnetic steel) and optimizing magnetic circuit design to reduce speed differences.
