In daily life, we often encounter different noise pollution. What is the reason why we all know what the noise of the contact core is? (1) Poor contact of the armature and the core contact surface or skew of the armature: After the armature and the core have been bumped several times. If the contact surface is worn or deformed, or if there are dirt, dust, etc. on the contact surface, the contact surface will be poorly contacted, resulting in vibration and noise during the attraction and acceleration of the iron core. Simultaneously. It will overheat the coil. In severe cases, the coil may even be burned. If the vibration is caused by oil stains on the end face of the core. Cleaning should be removed. If it is caused by deformation or wear of the end face, fine gauze can be used to lay it on a flat iron plate. Push the core back and forth to flatten the end. For the E-shaped core, care should be taken to maintain a 0.1-0.2 mm anti-remanent magnetic gap between the contact surfaces of the core columns. (2) Damage to the short-circuit ring During the operation of the AC contactor, the short-circuit ring embedded in the end face of the iron core may break or fall off after multiple collisions of the iron core. Short-circuit ring breaks occur at the corners or notches outside the groove, and the breakage can be welded or replaced when repaired, and reinforced with epoxy resin. (3) Mechanical reasons: If the contact pressure is too high or the moving parts are blocked. Make the armature and iron core unable to completely pull. Will produce strong vibration and noise. Iron core is a major concern for everyone.
