agnetic powder is used as a medium to transmit torque. Among the necessary materials for magnetic powder clutches/brakes are magnetic powder (granular magnetic powder). The application field of magnetic powder is very wide. Magnetic particle detection is extremely sensitive to the detection of defects on the surface of the workpiece. However, if the degree of defects on the surface of the workpiece is higher, the detection sensitivity will quickly drop to zero. The choice of magnetic powder clutch and magnetic powder brake can be seen whether there is magnetic leakage in magnetic powder detection. Magnetic powder clutch and magnetic powder brake must have magnetic powder in the necessary materials, so how to detect magnetic powder is the key part of selecting magnetic powder clutch and magnetic powder brake.
Magnetic powder must not get wet with water, oil, etc. After the magnetic powder is wet, the performance will be unstable, and care should be taken to avoid the intrusion of water, oil, etc. into the interior of the magnetic powder clutch and magnetic powder brake. The principle of magnetic particle detection by magnetic powder clutch manufacturers is that after the material or workpiece is magnetized, if there are cracks, cracks or other defects on or around the workpiece, a leakage magnetic field will appear in the defect, and the magnetic powder will attract and focus on the detection process. Magnetic powder is applied to form a defective display. If there is magnetic leakage, it will affect the performance and torque of the magnetic powder clutch.
Magnetic powder clutch brakes are suitable for a variety of working environments, so a variety of models and specifications have been produced. Different specifications of magnetic powder clutches require different amounts of magnetic powder to be filled. The larger the specification, the larger the amount of magnetic powder to be filled. The magnetic powder magnetized parts of the magnetic powder clutch will not cause all magnetic leakage phenomena. The production of magnetic leakage is related to the shape of the defect, the surface distance of the defect and the relative position of the defect and the magnetic force line. The material of the workpiece and the roughness of the surface of the workpiece It also causes magnetic leakage.
