How to repair the electric fan without shaking its head? Reason explanation
1, one of the reasons for not shaking your head is that shaking your head is blocked, which is caused by the deformation and bending of the connecting rod. At this time, there will be a "squeaking" sound, and the deformed connecting rod can be removed and taken out after shaping;
2. It is a transmission fault, which prevents the power from being transmitted. Check the toothed bar, swing head plate, gearbox and clutch, etc. , who found off, foreign body stuck, unable to engage after severe wear, etc. , the missing parts should be eliminated or replaced.
3. Oily bearings are mainly used for electric fans. This kind of bearing is usually a powder metallurgy product. Tightly wrapped in the oil hole inside the bearing for lubrication. When the electric fan works, the temperature of the motor rises, and the friction between the rotating shaft and the bearing generates heat, which will gradually consume lubricating oil. If the lubricating oil is not properly replenished, the fan motor will not be able to maintain normal operation, and the speed will be reduced or even turned, thus burning out the motor. During the use of the electric fan, you can refuel the electric fan from the oil filler every 1 ~ 2 months. Sewing machine oil or spindle oil can be used.
4. The reducer of electric fan uses lubricating oil (industrial vaseline or calcium-based grease), which is usually replaced once every 3 ~ 4 years. When replacing, first remove the back cover, remove the balance key, then remove the gearbox cover, gently scrape off the old grease inside with a small bamboo lamp tool, then clean it with clean gasoline, and then add a proper amount of new grease.
Precautions:
Shaking head is not only caused by the broken wire rope or loose head in remote control clutch or shaking head control device. If the steel wire breaks, a new steel wire flexible shaft can be replaced. If the tie head is loose, just re-fix the metal head of the casing.
There are two kinds of shaking control, one is to drive the connecting rod to shake its head through the reduction gear, that is, the gear will slip without shaking its head. The other is that the synchronous motor directly controls the fan to shake its head. In addition to the vibration motor itself, it is also possible that the control circuit and switch are broken. If it is a remote control fan, it may also be a problem with the driving transistor.
What I have introduced to you above is the specific operation of the electric fan without shaking its head. I also hope to learn more about the electric fan here. Some minor faults of the electric fan can be repaired by myself, so as to avoid wasting more money when going out to find a master. In fact, the maintenance method of electric fans is very simple. As long as you know what's wrong, I hope Bian Xiao's introduction today will bring you substantial help!
