Q:What is the function of the fan blade?
Most of the fans are three blades. In addition, the three blades have better dynamic balance, not easy to oscillate, thus reducing the wear of the bearings, prolonging the service life and reducing the maintenance cost
Q:Why does the fan seem to spin backwards when it spins?
This is the reason that the wheel looks stationary, when the frequency of the fan's rotation is related to the maximum frequency that the human eye can tell.
Q:Is the power consumption the same when the fan is used in different gears?
The maximum design speed is used as the design value, and the minimum speed deviates from the design value.Fan blade is also a sensitive load, the power of shaft and speed are three times, and the higher the speed, the greater the energy consumption
Q:How should an electric fan be used?
The wind speed that the fan opens should not be too big, so that the human body has an adaptive process. The best control indoor wind speed of 0.2-0.5 meters per second, especially in a well ventilated room and in it's place, a wind speed of the electric fan is not too large.
Q:How is the fan made up?
The control circuit is made of IC induction magnet, and the N.S. pole controls the coil through the circuit to generate internal excitation to rotate the rotor.
Q:Why can an electric fan choose only 123 winds, and this discrete value instead of zero to three continuous type?
That thing is easy to break, and the market demand is not big, so it is less and less
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
Q:What are the types of electric fans?
According to the structure of the motor can be divided into: a single-phase capacitor type single-phase, three-phase, shaded pole induction, DC and AC / DC series excitation commutator type electric fan.
Q:Does the fan blow the door open or closed?
If there is a natural wind. The wind blowing fan should pay attention to the natural wind, not to blow
Q:Where does the wind from the electric fan come from?
The air passes through the fan blade, because it is oblique, and when the air passes, the fan leaves the air straight, while the other side takes a diagonal line with the blade
