Thermosetting electromagnetic valve coil of textile machine FN1005

Three tricks to make it easy for you to repair the electromagnetic wire. Circle the fault reason and explain it.

1. Electromagnetic coil uses the attraction and release of armature to transmit power. The failure of electromagnetic coil is mainly caused by abnormal action caused by position disorder and non-work caused by coil destruction.

2. The dislocation of the electromagnetic coil will make the armature move abnormally. When the distance between the electromagnetic coil and the armature is too large, the armature will have a large stroke, which will lead to insufficient suction and no action; if the distance is too small, it will lead to misoperation. It is enough to readjust the status and make it stop.

3. When the electromagnetic coil does not work, the main reason is that the coil is destroyed and burned, resulting in the armature not moving. This can be measured by a multimeter, and its resistance value is infinite, which can indicate that the coil has indeed burned out. If the coil is intact, it indicates that the holding circuit of the electromagnetic coil is faulty. This can be used to measure the input voltage of the electromagnetic coil with a multimeter. If there is voltage, the fault is stuck in the armature. Make sure that it can move freely. If there is no voltage, the fault is in the working circuit.

How does the electromagnetic coil protection equipment work?

1. Introduction: In the power system, electromagnetic coil is widely used. In the aspect of high-pressure electrical appliances, it is used in the closing circuit and the opening circuit of high-voltage circuit breakers.

2. This machine is the most important switching device in the system. Under normal operation, the circuit breaker can connect and disconnect the load current of the electrical device; When the system has problems, it can reliably disconnect the short-circuit current, avoid the accident extension and ensure the safe operation of the system, so the control of the machine is the most important control operation of the system.

3. When its control machine gives the command of breaking brake, the electromagnetic coil of breaking brake is excited, and the system of starting valve or latch, after the release of hydraulic pressure, pushes the main contact of its arc extinguishing chamber to complete the breaking brake procedure. When its tripping procedure is completed, its moving contact A1 will be disconnected immediately, and the circuit of the electromagnetic coil of breaking brake will be disconnected. When it gives the closing instruction, its moving contact A2 will be disconnected immediately.
