What faults can cause instability in the operation of fire exhaust fans
When the device is running, you need to pay attention to the stable condition. If the operation is not stable, a failure may occur. At this time, we need to stop the inspection immediately so that it can be repaired in time. Fire-fume exhaust fan is one of the commonly used models in fans, and it will also be unstable during operation. In order to better inspect the equipment, we need to understand which failures cause it to become unstable?
After practical research, it is found that the following faults will cause the unstable phenomenon of the fire exhaust fan
during operation: 1. There may be a problem with the thyristor, which is open, shorted, or poor internal contact. 2. May be caused by a problem with the rectifier diode. 3. The adjustable resistance time is too long, which is prone to poor connection. 4. The carbon brush between the electronic rotor and the commutator is still alive, and the toner is defective, so you can debug the resistance first, and then test it. If it is caused by the above four faults, we can take corresponding measures to solve it.
