Why did the blades of the eternal electric fan fall off?

The blades of the eternal electric fan will fall off, because to a certain extent, the screws may be loose, or it is a long time ago, so the Shanzhi page falls off.

The blades of the eternal electric fan fall off, which is caused by the loosening of the screws of the shaft head, it is recommended that you check the fixing screws of the fan blades.

If the blade of the electric fan falls off, it is necessary to see whether it is snapped up or screwed up, if it is screwed, it must be loose before it falls off, if it is buckle card, it can be clamped directly.

Why did the blades of the eternal electric fan fall off? It was because the installation was not firm enough, and because it rotated up, the vibration force was very strong, and it fell off.

The blade of the electric fan falls off, which proves that this electric fan has been broken, and this leaf has been broken, so it will fall off, so you have to buy a new one.

If the blades of the eternal electric fan fall off, it means that the parts are not tightened or the quality is not good.

Your electric fan blades have fallen off, it should be that the screws on it are loose, reinstall it, and it will be fine.

That's because the screws on the blades of the electric fan are loose, and if you tighten it, it won't fall off.

Because it takes a long time, the battery needs to be replaced, and its leaves will fall off for a planning repair.

The leaves of this electric fan are not locked firmly when they fall off, so they will fall off or they are aging.

Hello, it's very unsafe for this fan blade to keep falling, so you can't use it anymore, buy a new one.

This should be a quality problem, in fact, things like electric fans should be safe, because it is very fast when it rotates.

Why do the leaves of the immortal electric fan fall off? This is because it was produced many years ago and has passed its expiration date.

Because the tension spring of the motor should be loose.

The blades of the fan are all off, of course, it is a very serious quality problem.

Why do the electric fan blades fall off? Which piece is broken? Or maybe there is a problem with the quality, so it will fall off.

1. Disassemble the box and place all kinds of parts of the electric fan on the ground.

2. Take out the bottom basin and branch pipe, remove the nut and put it into the empty groove in the middle of the basin, and then twist the nut tightly.

3. Twist the glue nut on the branch pipe.

4. At this time, you can adjust the fan as high as you need according to your own needs, and you can also adjust it later.

5. Pick up the fan head, loosen the screws at the back, plug in the fan head, and tighten the screws.

6. Twist off the shield of the fan screw head, put him aside, and then remove the inner shield when you need it.

7. Put the back cover of the fan on, aim at the card slot, otherwise it will loosen, and twist the cover when you put it away.

8. Install the fan blades, and then twist the first removed cover and twist it up, remember to tighten it. Remember to put the fan blades into the card slot and then tighten them.

<>10. At this time, tighten the cassette on the front cover of the fan, only half of it can be twisted, and then press it with the back cover of the fan, and then see if other parts have entered the card slot, and tighten the screws when all are in.

11. The last step is to see if the blades of the electric fan touch the shield, if there is, remove it and readjust it, if not, plug it in to try the wind, remember to start from the first gear.

The specific solution to measure the quality of the electric fan motor with a digital multimeter is as follows: use the multimeter block to measure the resistance value between the motor terminals, if there is an open circuit, then there is damage. Green, pass is good, black line and red, the three groups are not connected, blue, yes but one group is not good The steps to test the quality of the capacitor with a digital multimeter are as follows:

To judge the polarity, first adjust the multimeter to 100 or 1k ohms, assume that one pole is positive, let the black watch pen connect with it, and the red watch pen connect with the other pole, write down the resistance, and then discharge the capacitor, that is, let the two poles contact, and then change the meter pen to measure the resistance, and the black watch pen with a large resistance value is connected to the positive pole of the capacitor. Adjust the multimeter to the appropriate gear in ohms, and the principle of gear selection is: 20k gear for 1 F capacitor, 2K gear for 1 100 F capacitor, and 200 gear for more than 100 and F.

Then use the red pen of the multimeter to connect the positive pole of the capacitor, and the black pen to connect the negative pole of the capacitor, if the display increases slowly from 0, and finally shows the overflow symbol 1, the capacitance is normal, if it is always displayed as 0, the capacitor is shorted internally, and if it is always displayed as 1, the capacitor is internally open.

The main reason why the air guide blades can't stop may be that there is a problem with the control system.

As a result, it cannot be stopped in time.

What brand of electric fan is best What brand of electric fan is good? I think the beauty is good, but the air conditioning fan of my home Shanghai Eternal Gree Midea Jinlong Midea is good (

Yongsheng brand electric fan is really okay, I have one at home, I bought it in 2004, full remote control, it's still very good to use, it's very quiet, and now I still want to buy one, so I'm looking for this brand everywhere.

Emmett floor fans are good, quiet and durable.

The key is to have a copper wire motor and a warranty for several years. Eternal life is an old brand, and it's okay.

Orida's pure copper motor fan is very powerful!

Buy a fan electronic governor and remove the governor housing, which is a very small circuit board. Drill a small hole in the place where the fan is installed on the remote control circuit board, and install the speed control circuit board. You must sell electronic ones, and you can't buy transformers (transformers can't be installed).

The electric fan starts slowly, just replace the capacitor of the motor start.

The power cord is broken. Or there is an open circuit. The remote control fan generally does not break the circuit board.

The more common ones are 5V regulator tube breakdown or buck capacitor failure! Friends in Beijing can call 010-57439160 for consultation!

If the power cord or circuit board is damaged, find a professional to repair it, or find after-sales service.
