3. When repairing or replacing the relay, first remove the national relay spring, and then pull out the relay. Do not use excessive force or shake left and right when pulling it out, as it may damage the relay or socket. Faults and troubleshooting methods 1. The relay contact has no output The analysis and elimination methods of the relay contact without output are as follows: (1) Make sure that the relay and socket should be reliably plugged in; (2) Check that the relay should not be mechanically blocked. If foreign matter in the relay blocks the armature, the armature cannot work reliably (forward rotation) or release (reverse rotation), and the contacts cannot be reliably contacted; (3) Check that there should be no foreign matter between the contacts, there is foreign matter between the contacts, and the contacts cannot be reliably contacted; (4) Check that the contact resistance of the relay contact should not be too large. 2. The relay does not work or the relay with a pole cannot be reversed in the forward direction be reliably released.

The electromagnetic system includes coils, iron cores, vehicle irons and armatures. The coil is installed horizontally on the iron core, and is divided into a front coil and a back coil. The use of dual coils is to enhance the flexibility and flexibility of the control circuit, which can be controlled by a single coil or a series of double coils according to the circuit needs. The armature is fixed on the blade of the yoke by a butterfly-shaped steel wire, which is flexible in movement. There is a heavy hammer in the transmission part of the Yantie to ensure that the relay armature returns reliably by gravity. The number of weights installed is determined by the structure of the relay contact system, and should be able to ensure the reliable release of the relay. A stop piece is installed at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit of the relay, prevent the ferromagnetic parts of the magnetic circuit from magnetizing, and ensure that the relay falls reliably. The iron core, vehicle iron and armature of the relay are made of electromagnetic pure iron, which has high magnetic permeability and small remanence.
