Sealing principle

Magnetic coupling belongs to non direct contact sealing. Composed of a drive shaft, a driven shaft, a housing, inner and outer rings with strong magnets, and a spacer sleeve. The principle of using strong magnetic materials to repel each other of the same sex and attract each other of the opposite sex, as well as the characteristics of magnetic field lines penetrating non ferromagnetic materials.
When the motor drives the drive shaft to rotate, the outer magnetic rotor drives the inner magnetic rotor inside the dynamic sealing sleeve to rotate synchronously through magnetic force, thereby achieving non-contact transmission of torque.
