Tips: Noice of AC Contactor, How to Solve?
Possible causes of failure:
- Insufficient power supply voltage, insufficient electromagnet suction.
- The magnetic system is improperly assembled or shaken by vibration or the parts are stuck, the core cannot be absorbed.
- The surface of the pole is rusty or foreign matter (such as grease, dust, hair, etc.) invades the core surface.
- Contact spring pressure is too large.
- Short circuit ring break.
- Iron core pole wear is excessive and uneven.
- Coil turn-to-turn.
Maintenance method
- Increase the voltage of the operating circuit.
- This system should be adjusted during processing to identify and eliminate the inflexibility of the machine.
- Clean the core face.
- Replace the core or short circuit ring.
- Replace the coil.
