Q:The electric fan is moving all the time. Why is there a lot of ash on the leaves? Ash won't fall when you blow it?
When the fan rotates, it drives the surrounding air to flow, and the ash doesn't float up.
Q:Where does the wind from the electric fan come from?
The Bernoulli principle. Just like an airplane has wings,
Q:What is the difference between air conditioner speed regulation and electric fan speed regulation?
Variable frequency air conditioning is to change the frequency of motor power supply to achieve speed regulation, in fact, the frequency adjustment will also change the voltage.
Q:What are the common faults of electric fans?
If a fan is used for a long time, the motor will be worn out and the shaft sleeve of the motor will be burnt easily after being abraded
Q:Can the electric fan blow to the notebook computer?
Yes, but over time, the screen will be gray and cleaned up. If you consider the heat dissipation, the fan effect is normal, and the electricity costs
Q:What is the function of the fan blade?
Fewer leaves are likely to produce greater wind pressure, but the noise is greater, while the number of leaves is the opposite
Q:What is the principle of a vaneless fan?
The base will be a large amount of air from the suction hole at the bottom of the 5.28 gallons per second flow inhalation, then the air is pressurized into the annular inner wall, an impeller inside the edge of the ring in the air circular trajectory jet, change the air flow will cause the air pressure, and ultimately the formation of a cold air flow shares uninterrupted
Q:Why do most fans only have 3 blades?
We usually use the fan for axial fan, the blade is odd, this is because if the even shape symmetrical blades, and no adjustment of balance, it is easy to make the system resonance occurs, if the blade material is unable to resist fatigue due to vibration, will cause the blade or the spindle is broken, so odd pieces of the fan blade design on asymmetric multi axis design
Q:Why can an electric fan choose only 123 winds, and this discrete value instead of zero to three continuous type?
Because, for example, Class 1.5, the volume of air can be settled by the distance between the fan and the person.
Q:Where does the fan drip the oil?
After turning, the net cover is turned downwards, the shell of the back of the motor is removed, the rotating shaft and the swinging head mechanism of the tail of the motor are exposed, and 4-5 drops are dropped along the root of the rotating shaft, and the back shell is installed after the oil is penetrated
