What is the reason why the electric fan has no wind, and what is the reason why the electric fan has

The reason why the fan is not windy is as follows:

The first point may be that the electric fan has not been cleaned for too long, and the electric fan is rotating but there is no wind. The fan surface and air outlet of the electric fan that have not been cleaned for too long will attach a large amount of dust and other debris, which will block the air outlet of the electric fan, and will also cause the speed of the electric fan to weaken, so that the wind power of the electric fan will be reduced. When you have free time, you can turn on the electric fan and clean and wipe the fan blades, air outlets, protective nets and other parts inside.

The second point may be that the motor lubrication of the electric fan is not good, the motor can not drag the fan blades, and after removing it, it will be found that the shaft can still operate normally, which means that the fan motor is not broken, but the motor lubricating oil is insufficient, resulting in insufficient speed of the electric fan and less air outlet. You can turn on the electric fan and apply some lubricating oil to the motor of the electric fan.

The reasons why there is no wind in the electric fan are as follows:1. The fan blade is not tightened well, if it is loose, tighten and fix it in time.

2. The fan blade is installed in the wrong direction and needs to be removed and reinstalled.

3. The fan blade is not the original fan blade with poor stirring ability, if the fan blade is too small, it will also lead to no wind, and it can be replaced with the fan blade of the original machine.

4. If the fan blade is damaged, resulting in the weakening of the wind leakage, the new fan blade can be replaced in time.

5. The surface of the fan blade is too dirty, resulting in weak wind, so clean it in time.

1. It may be caused by the fact that the electric fan has not been cleaned for too long, and a large amount of dust will be attached to the fan surface and air outlet of the electric fan, resulting in the weakening of the speed of the electric fan. In this case, you only need to clean the fan blades, air outlets, protective nets and other parts.

2. It may be that the motor lubrication of the electric fan is not good, and it cannot be caused by the fan blades. If the shaft can still run normally, it proves that the motor is normal, but the motor lubricating oil is insufficient, resulting in the slow speed of the electric fan and less air outlet, as long as the motor is coated with some lubricating oil.

3. The age of the electric fan is too long, and the gap is too large after the wear of the shaft sleeve of the motor, which makes it impossible to drag the fan blade load, resulting in the motor being easy to burn out, making the internal resistance of the motor larger, and unable to drive the fan blade to rotate.

If there is no wind in the electric fan, it is generally a problem with the motor!

1. There is no power on the inside.

The wiring of the fan switch and timer Bai is disconnected, causing the fan to not be powered on normally.

Listen to whether there is a motor sound or not, and you can judge.

Solution: Replace the damaged part, or reconnect the wires.

2. The starting capacitor fails.

The capacitance of the starting capacitor decreases, resulting in the failure to start the motor properly.

The hand can turn the fan blade, which can be judged.

Solution: Replace the CBB61 starting capacitor of the same model.

Electric fan, also known as fan and fan, is a household appliance that uses an electric motor to drive the fan blades to rotate to accelerate the circulation of air, mainly used to cool off the heat and circulate the air. It is widely used in homes, classrooms, offices, shops, hospitals and hotels.

A fan is mainly composed of components such as a fan head, blades, grille, and controls. The fan head includes an electric motor, front and rear end covers, and a moving head air supply mechanism. The main components of an electric fan are:

AC motors. Its working principle is that the energized coil rotates under force in a magnetic field.

Electrical energy is converted into mechanical energy, and at the same time, due to the resistance of the coil, it is inevitable that some of the electrical energy will be converted into thermal energy.

Common household fans are essentially axial fans, i.e., the direction of the wind is parallel to the axis of rotation of the fan blades.

There are many reasons why the electric fan has no electricity, first, the socket is out of power, second, the plug is broken, third, the wire is broken, fourth, the motor is burned, fifth, the electric fan switch is not turned on, sixth, the switch is broken, seventh, the internal wiring is disconnected, and so on will cause the electric fan to run out of power.

There are many reasons for this.

If the plug wire is broken, check the timer, socket, fuse, timer, gear switch, stator winding if it is normal, it is the shaking head part of the wire is broken, or an overvoltage protection element (shaped like a porcelain capacitor) connected in series of windings is burned, and the emergency can not use him, directly connect the two ends, and then replace the component when you buy it! If there is a down-and-stop function, it also depends on the down-down switch, and the gear switch will also have problems, and then there is the motor.

Fan. The causes and solutions for turning but no wind are:

1. The electric fan is a household 220V alternating current.

Power supply: 1. The fan blade is reversed: there is no wind on the front side, but there is it on the reverse side. (Generally, it is likely to occur, because the blades are reversed and cannot be installed).

2. Deformation of fan blades: remove the fan blade cover, and tilt each fan blade at a certain angle according to the rotation direction of the motor.

Second, the electric fan is used 380V AC power supply for industrial use

1. There is no wind on the front and there is on the reverse side, the power line is reversed, and any two of the three incoming wires can be reversed.

2. There is no wind on both sides of the front and back, and the method of the first point and paragraph 2 above is used to solve it.

Features of the electric fan::

1. Natural wind: imitate the natural gusts of wind by the sea.

The wind speed is sometimes large and sometimes small, sometimes and sometimes there is no time, elegant and comfortable, which satisfies the psychology of returning to nature, and can also effectively prevent the damage caused to the human body when the air is supplied at a constant speed for a long time.

2. Sleep wind: the air supply is similar to the simulated natural wind, but the wind speed is smaller than the conventional wind of the same grade, and the timing is set, after the air supply reaches a certain time, it will automatically stop once, and the longer the timer, the longer the downtime will be, and the wind speed will gradually weaken, effectively preventing the cold and flu and other diseases caused by the decline in resistance of the human body during sleep.

3. Timing: The stop time can be set.

4. Remote control: control the fan from a distance.

The fan blades of the electric fan are installed incorrectly, or the fan blades are installed in reverse, check whether there is wind behind the fan, if there is wind, it means that the fan blades are installed in reverse.

There is also a possibility, if it is a fan blade, it is not a whole, it is a scattered installation, it may be that the fan blade as a whole is not coordinated, or because the fan blade itself has been deformed and cannot produce the effect of air out. In this case, the only way to do this is to replace the blade with a new one, or simply attach the blade to its original shape.

If the fan is still rotating, but there is no wind, it may be that the wind arithmetic is too low, or the dispersion sheet has been eliminated and needs to be replaced.

The quality of the electric fan is not good.

The reason why the electric fan is on but there is no wind may be the following situations, and the specific situation and solutions are as follows:

1. It may be that the fan blades are reversed, and the fan blades are reversed, which will not affect the electric fan, and can still rotate, but there is no wind, and the fan blades only need to be removed and reinstalled.

2. The back of the electric fan may be too close to the wall, resulting in air convection, so you can move the electric fan to a ventilated position.

3. The internal resistance of the motor will become larger and the load capacity will be lower after the motor is used for a long time, resulting in the inability to drive the fan blade to rotate, and the excessive shaft clearance of the motor will also cause the fan blade to not rotate due to the inability to load. Replacing the motor with a new one will solve the problem.

4. It is also possible that the lubrication of the motor is not good, resulting in the motor being unable to drive the fan blades to rotate, so that there is no wind, and an appropriate amount of lubricating oil can be added.

Pay attention to the position of the electric fan, not too close to people, too close will lead to a large gap between blood circulation and sweat circulation, and blowing at close range for a long time, the human body will feel uncomfortable. The electric fan is placed about 2 meters away from people, so that the wind is more uniform and soft. It is also necessary to avoid long-term direct blowing, which will cause discomfort to the human body and have a certain impact on the human body.

At the same time, the wind speed should be set, not too large, to ensure that the human body can adapt to the use.

1.When the fan blade is installed on it, the motor is not dragged, and the shaft will be found to be able to operate normally after being removed, which means that the fan motor is not broken.

2.Also, you have to consider how long the electric fan has been used, the motor of the electric fan will be lost, and the shaft sleeve of the motor will be easily burned out after wearing.

If the motor is used for a long time, the internal resistance of the motor will also become larger, and the load capacity will become lower, resulting in the inability to drive the fan blade to rotate. In addition, the axial clearance of the motor's rotating shaft is too large, which will also cause the load to be unable to be dragged.

3.Most people may encounter the following phenomenon, the electric fan does not rotate, you use your hands to pull it out or it will take a long time to slowly turn up, and after using it for a period of time, you find that it will not move when you pull it out by hand. The possible reason for this phenomenon is that the starting capacitance inside the fan has become small enough to rotate the motor.

Fans are relatively common in daily life, and in the process of using fans, there may be some problems.

1. What's going on with the fan only turning and not supplying air?

1. Install the fan blade upside down, there is no wind on the front, but there is wind on the back side, you need to remove the fan first and re-install the fan blade.

2. The fan blades are deformed, and each fan blade in the fan needs to be tilted in the direction of rotation.

3. If the power cord is reversed, the power cord is reversed, two of the three incoming wires need to be reversed, and the power switch needs to be turned off before wiring.

Second, the advantages of electric fans.

1. Compared with air conditioners, electric fans are more energy-saving and energy-saving, so the amount of electricity that needs to be consumed is relatively small, and after being turned on, you can feel the natural wind, which is more comfortable to blow, and the wind speed can also be adjusted.

2. Some electric fans also have a timing function, you can time the electric fan before going to bed, and the electric fan will automatically turn off after the time.

3. Some electric fans are relatively small, so it is very convenient to carry, usually when outdoor activities, you can hold the electric fan in your hand, the wind power is relatively large, and the power consumption is relatively small, from the appearance of the shape is very beautiful.

3. Precautions for using electric fans.

1. When using the electric fan, the position of the electric fan needs to be corrected, so that the electric fan cannot be in an inclined state, and the position of the electric fan cannot be too close to the person.

2. When using the electric fan, you can't blow it on people for a long time, otherwise it is very likely that you will have a cold or body pain, try to set the electric fan to the head rotation mode.

3. When the electric fan is turned on at the beginning, the wind speed should not be too large, and the wind speed needs to be controlled in a suitable gear, so that people can have a good adaptation process.

There is no wind on the front of the electric fan, and there is wind on the back, which means that the fan blades are reversed, and the other situation is that the direction of rotation of the motor is reversed (it may be that the starting winding is broken and there is an external force when starting).

Can you think that if the electric fan has been rotating, but there is still not much wind compared to the ECG fan you bought before, this is a problem with the blades of your electric fan, and you also need to take the head of the electric fan down with a knife, readjust the country, and then put that protection, network, cleaning will be much better.

It is the direction and angle of the fan blades that are wrong, or it is possible that the speed of rotation is too slow, which affects the size of the air volume.

That's the fan blades, and he's stirring up the air.

It should be running in reverse, so there is no wind, and I am really helping you look forward to it

The reasons are several situations: 1. It may be that the fan blades are reversed. 2. The reverse side of the electric fan may be too close to the wall, resulting in air inability to convection.

3. The internal resistance of the motor will become larger after a long time, and the load can become lower, resulting in the inability to drive the fan blade to rotate, and the excessive shaft clearance of the motor will also cause the fan blade to not rotate. 4. The smoothness of the motor is not good. 5. The fan blade of the electric fan is plastic, which is made by the deformation of the fan blade.

The enameled wire in the motor is overheated, and some of the enameled wire inside is not insulated due to overheating or other reasons, which will cause the motor to drop magnetically and reduce the speed. Solution:

It will not affect the electric fan, it can still rotate, but there is no wind, you only need to disassemble the fan blades and reinstall it to deal with it.

Move the fan to a ventilated position.

Replace it with a new motor and you'll be able to handle it.

Add an appropriate amount of smooth oil to the motor.

5. Repair the front elevation angle of the fan blade (repair it with a hair dryer) or directly cut the deformed part of the front elevation angle with scissors.

6. If you have just bought it, it is recommended to replace it again. The old fan is sent for disposal.

7. Check whether the fan blades of the electric fan are installed and fastened, and tighten and fix them in time if they are loose.

8. Check whether the fan blade is not the original fan blade, if the fan blade is too small, it will also lead to no wind, and it should be replaced with the fan blade of the original machine.

9. Check whether the surface of the fan blade is dirty and clean it in time.

1. If the fan blade of the fan is not from the original machine, or the fan blade size is too small, then the wind generated is also very small, or even there will be no wind, and the fan blade matched by the original machine needs to be replaced.

2. Or the electric fan has been used for too long, and the fan blades and other parts are contaminated with more dust, which hinders the normal operation of the fan, and there will be no wind linearity. The fan needs to be disassembled in time and cleaned properly.

3. It is also possible that the motor of the fan is not lubricated enough, resulting in the inability to drag the fan blades. At this time, you need to disassemble the fan, apply an appropriate amount of lubricating oil, and then install it back to use normally.

Fan failure: The fan does not rotate, but there is a humming sound. Such faults are generally the motor shaft is stuck, the capacitor is defective, or the starting winding is broken, the starting is broken, the short circuit, etc. Among them, it is more common for the rotor and the shaft sleeve to be stuck due to the lack of lubricating oil, you can remove the end cover to extract the rotor, wash it with kerosene, and soak it in No. 20 engine oil (or sewing machine oil) overnight to make it flexible and free of jamming.

The next day, it was installed in the same order, and the sticky washer should be soaked in oil again, and after such repairs, the electric fan turned again. If the starting winding is short-circuited or partially burned, the only way to replace the motor or rewind each winding of the motor is to replace the motor.
