Because it was usedElectric fanThe function of the natural wind or the sleeping wind.
The electric fan of the remote control series has three functions: ordinary wind, natural wind, and sleeping wind, and the air volume of ordinary wind is constant, and there will be no big or small; The natural wind is mainly aimed at the wind force of nature, which is large and small, and simulates the control circuit that can periodically change from strong to weak, and then controls the speed of the motor to be fast and slow; The principle of sleep wind is the same as that of natural wind, and it also uses a control circuit from strong to weak to control the speed of the motor.
Attention should be paid to electric fans in use:
1. Read the instruction manual in detail before use, and fully grasp the structure, performance, installation, use, maintenance methods and precautions of the electric fan.
2. After the electric fan is used for a long time, the bottom of the fan blade is easy to be stained with dust, which is due to the friction between the running fan blade and the air so that the fan blade carries static electricity, which is easy to attract fine dust floating in the room. The oil or dust accumulation of the electric fan should be removed in time, and a neutral detergent and soft cloth should be used for cleaning to avoid damaging the surface or coating of the shell. When disassembling and assembling the fan blades, pay attention to protect the fan blades and do not deform the fan blades to avoid vibration or shaking when the fan is running.
3. If there is a fault such as hot hands, abnormal burnt smell, or slow speed of the electric fan during use, do not continue to use it, and cut off the power supply in time for maintenance.
4. When using electric fans in summer, avoid blowing for too long and too strong after the heat, it is best to use shaking head, low speed, and natural windshield, and sleep with the wind when sleeping.
5. Families with children should pay special attention to the safety of the use of electric fans, place the electric fans in places that are not easy for children to touch, and educate children at home not to touch the fan blades out of curiosity to prevent accidents.

There are several reasons why the fan wind will be big and small, the first may be caused by the voltage instability in the area, the second point may be that the fan has been used for too long, the motor bearing is seriously worn or the lack of lubricating oil is made, and the second is that there is a problem with the capacitance of the fan.

Electric fans can rotate, but the airflow is small for the following reasons:
1. The fan has been used for a long time without maintenance, which increases the friction of the motor bearing and thickens the oil stain, which hinders the rotation of the electric fan.
2. The electric fan motor is a single-phase motor, and there are two sets of coils in the single-phase motor, one is the main coil which is also called the running coil, and the other is the secondary coil which is also called the starting coil. The circuit diagram of the electric fan is as follows:
If the rotation speed of the electric fan is slow, it may be that there is a short circuit between the turns in these two sets of coils, which cancels each other out and reduces the magnetic force, and the motor rotates weakly and the speed decreases. You can open the plastic shell of the fan to see if the color of the motor coil is black, if there is, it means that the motor has burned out and needs to be repaired or replaced with the same type of motor.
3. The motor bearing is seriously worn, and the radial clearance increases, which makes the motor rotor and stator rub against each other. It is recommended to replace the motor bearings.
4. The mains power supply voltage is too low, and the fan cannot be moved.
-
The electric fan rotates, but the air volume is small, which is not enough speed, so the air volume is small. If the power supply voltage is normal, there are two scenarios:
1. When the electric fan is turning, you can hear the [humming] sound of the motor. Power failure, unplug the power supply, dial the fan blade by hand, the fan blade rotation is not flexible, indicating that the motor bearing has been running for a long time and lacks oil, disassemble the electric fan and add oil to the bearings at both ends of the motor, you can eliminate the fault;
2. There is no buzzing sound when the motor runs, and the fan blade is rotated flexibly by hand, which may be due to the reduction of the starting capacitance capacity of the motor, which makes it difficult to start the electric fan, even if it can be started, but the speed is very slow. Replace a capacitor of the same specification to eliminate the fault.
-
First of all, the gear is low and the gear is large, and then the voltage is insufficient, the speed is slow, the wind speed is small, and the sound is loud, and it will burn after a long time.
-
Hello, the electric fan has very little wind, generally the voltage is insufficient, the contact is poor, and the motor is faulty.
-
If the electric fan rotates too slowly, it may be that the bearing is not lubricated well, or the starting capacitor capacity of the fan is insufficient.
-
First of all, let's take a look at how to solve the noise problem caused by the fan. There are many reasons why fans can cause a lot of noise, so let's take a look at each of them. If the noise of the computer fan is usually very small, but when the high load is running, the sound of the fan becomes louder, which is generally due to the performance of the fan can not meet the needs of the processor or graphics card heat dissipation, the current cooling fan can automatically adjust the speed, when the processor or graphics card heat is low, the fan will rotate slowly, when the computer is running at high speed, the heat will increase, the speed of the fan will be accelerated, then the fan will make a loud sound, to solve this problem you need to replace the heat sink with better performance, Or replace it with a silent fan.
If the fan suddenly makes noise after a long period of use, it is generally caused by the loose fixation of the fan or a lot of dust, you can open the case to clean up the dust and reinforce the loose fan in the case.
Switching to an SSD is a solution to the problem that the mechanical hard disk reads and writes is a way to make noise once and for all, but the cost of this solution is too high, and our solution can only be to put the mechanical hard disk at the bottom of the chassis, away from the noise source.
If the hardware has passed the shelf life, you can try to use 502 glue to drop into the inductor that emits the acoustic noise, and the coil can also be fixed to reduce the acoustic noise, but this method is risky, and any adverse consequences occur, and the good thing is not responsible.
-
1.The speed of the fan is intelligent.
2.When the temperature inside the case is high, the fan speed is relatively fast, and the sound is louder.
3.If the temperature is low and the minimum is the rotational speed, the sound will be quiet.
4.Especially when playing games, the graphics card fan and CPU fan speed are very fast, and when working on documents, it is very quiet, and this is the reason.
Use 360 Security Guard, Master Lu and other software to optimize the program again, uninstall unnecessary programs and slim down the system. It will be of some help to your machine, and the rest will be difficult to do, clean the fan, you can't do it yourself, you can only let the after-sales service help you get it.

Your CPU fan is a smart fan.
You can set the temperature of the CPU by yourself, which can generally be set in the motherboard BOIS, for example, if you set the average temperature to 45
Full load temperature 48
Turn off the system temperature 60
So, if your computer's CPU temperature is below 45 degrees, the fan speed will be low, and the noise will be very low.
If your computer's CPU temperature is higher than 45 degrees, the speed of the fan will slowly increase to 48 degrees, when the fan is running at full capacity.
At this time, of course, the noise is the highest!!
Turning off the system temperature has nothing to do with the fan speed.
This is just to protect the CPU, in case the fan is broken, the temperature will continue to rise to the set 60 degrees, and the computer will automatically shut down.
In addition, the temperature of the CPU has a lot to do with the number of programs running on the computer, and the standby temperature of my computer is 37 degrees (fan 1500 rpm).
I play a game and open a number to 42 degrees (1800 rpm) after a while, and open three numbers to 52 degrees (2400 rpm)!!
The most awesome one is 57 degrees (5600 rpm).

Summary. What is the reason for the sudden decrease in the wind power of the electric fan 1, due to the long-term use of the fan blades, when rotating, the dust attached to the air will be deposited on it, and there are a large number of dust mites, so the rotation speed of the blades is reduced, and the dust can be cleaned and dried at this time; 2. There is too much dust in the shell grille, which causes the wind to be unable to blow out smoothly, which will make people feel that the wind force becomes smaller. 3. After the electric fan is used for a period of time, it will not run smoothly due to the lack of lubricating oil, and the wind power of the electric fan will suddenly become smaller, so you can add a little lubricating oil to the place where there is a shortage of oil; 4. Another main reason for making the electric fan slower and slower is the aging of the components, so that the wind power becomes smaller is very obvious, and the aging of the motor can only be replaced by the motor, which can be replaced by yourself or by looking for a professional repair shop for replacement; 5. After the electric fan is used for a long time, the capacitance capacity will become lower and lower, resulting in the starting torque of the motor becoming smaller and unable to drive the load, so the wind will suddenly become smaller, and the solution is to replace the new capacitor.

I just bought it, I used it, and just now the power at home suddenly stopped and recovered, and the wind power of the electric fan was very small.
This can be imitated because the grid voltage is too low, and the starting torque of the electric fan becomes smaller, so the wind speed of the electric fan becomes smaller after stopping. When the voltage is stable, the wind will be a little stronger.
The voltage is unstable and the voltage is low.
That's right. Okay thank you.

There are several reasons why the wind of the fan is getting smaller and smaller:
1. Be cautious that the fan blades have too much dust, resulting in a decrease in speed.
2. There is too much dust on the shell cover, resulting in an unobstructed air duct.
3. The motor is aging, resulting in a decrease in speed.
Common faults of electric fans:
1. The fan shaft part should ensure that there is lubricating oil, otherwise the fan blade cannot be dragged by the motive on it. If you are at home, you can choose to turn off the power and then turn the fan blades, if the rotation is stiff, there is basically no lubricating oil.
2. Wear and tear caused by long-term use. If a fan is used for a long time, the motor will be lost, and the shaft sleeve of the motor will be easily burned out after wearing.
3. The fan does not rotate due to overheating. There is a motor in the fan device, and there will be an overheating circuit breaker in the motor, if there is a short circuit in the coil winding, the heat will increase in a short time, and the motor will not move in this case.
4. The capacitance of the starting capacitor becomes smaller. When the fan is used for a long time, the capacitance capacity will decrease, resulting in the starting torque of the motor becoming smaller, and the load cannot be driven.

Summary. There may be several reasons why a small fan becomes less windy:1
Power supply issues: If a small fan is battery-powered, the battery may run out of power and cause less wind. Or if the power supply is plugged in, the power cord may be loose or damaged, affecting the stability of the power supply and causing the wind to weaken.
2.Fan blade problems: The blades of a small fan can be damaged or deformed due to prolonged use or friction, resulting in reduced wind force.
Check that the blades are clean and complete. 3.Fan motor issues:
The fan motor is the core component that generates the wind, and if the motor fails or wears out, it will cause the wind to decrease. You can try cleaning the motor or replacing the fan. 4.
Blockage or obstruction: Fan air inlets or outlets can be blocked by dust, dirt, or other objects, obstructing wind flow. Cleaning or removing any obstructions may restore normal wind strength.
If none of the above measures work, it is recommended to contact the manufacturer or professional maintenance personnel for inspection and repair.
There may be several reasons why the wind front of the small fan does not have the strength to become smaller:1Power supply issues:
If a small fan is powered by a battery, the battery may run out of charge and cause less wind. Or if the power supply is plugged in, the power cord may be loose or damaged, affecting the stability of the power supply and causing the wind to weaken. 2.
Fan blade problems: The blades of a small fan can be damaged or deformed due to prolonged use or friction, resulting in reduced wind force. Check that the blades are clean and complete.
3.Fan motor problem: The fan motor is the core component that generates the wind power, such as silver or nano motor failure or wear and tear, which will cause the wind to decrease.
You can try cleaning the motor or replacing the fan. 4.Blockage or blocking:
Fan inlets or outlets may be blocked by dust, dirt, or other objects that impede air circulation. Cleaning or removing any obstructions may restore normal wind strength. If none of the above measures work, it is recommended to contact the manufacturer or professional maintenance personnel for inspection and repair.
Can you tell us more about that?
The reason why the wind power of the small fan becomes less may be due to the following factors:1Dust accumulation on fan blades:
After prolonged use, dust accumulates on the fan blades, causing obstruction of air flow and reducing wind power. Cleaning the fan blades regularly can solve this problem. 2.
Low battery: If the small fan is battery-powered, when the battery is low, the output current will drop, causing the wind to weaken. Charging or replacing the battery can solve this problem.
3.Motor issues: The motor of a small fan may cause performance degradation due to prolonged use or wear and tear, etc.
In this case, the motor needs to be repaired or replaced. 4.Power issues:
If the small fan is powered by a power supply imitation wax, it may be that the power supply system is faulty and the current output is unstable, which will affect the wind power. Checking the power connections and making sure the current is stable** can solve this problem. In summary, the reduced wind power of a small fan may be caused by dust accumulation on the fan blades, insufficient battery power of the Beimin Slip, motor problems, or power supply problems.
Taking appropriate measures such as cleaning, replacing, repairing, etc., according to the specific situation, can solve this problem.
In this way, you will understand that there is indeed a problem with your fan, but when your computer is standby, the CPU usage is low, the fan speed is low, the CPU is used a lot, the fan speed is fast, if it is a normal fan, whether it is fast or low, the sound is not so obvious, and there is not so much noise. >>>More
That's the sound produced by the CPU fan working, as the CPU processing tasks gradually increase, the fan on the CPU will speed up, and there will be a burst of noise inside the inverted case, which is normal! There is also an increase in dust on the CPU fan, generally these two possibilities! It also means that your computer needs to be dusted up, or the configuration needs to be improved!
To ensure that the computer is normal and free of viruses and malware, it is recommended to use a cleaning tool to clean up the system junk and temporary files (IE cache) generated by the Internet on a regular basis to detect and kill malware. Restart your computer when you're done. >>>More
That's a problem that belongs to the telcos.
In the case of charging high for a while and low for a while, it is recommended that you try the following: >>>More
