Q:Is the power consumption the same when the fan is used in different gears?: Asynchronous motor efficiency is a very delicate thing, when the speed is similar to the design speed, the efficiency is very high, when the deviation is large, the efficiency is very low. Therefore, the speed range of the general fan is also very small

Q:What are your misunderstanding blowing ？: The electric fan to blow away from the body should not be put in place very close to the near side if the strong winds, and only the wind blowing body, make the skin sweat evaporates quickly, the temperature decreased significantly, but not with the wind blowing side, slow evaporation of sweat, sweat and blood circulation causes the body to both sides of the discharge gap is too large. The nerve center will lose balance, once for a long time, each organ will feel terribly fatigued, and malaise

Q:Which items should we pay attention to selecting electric fans?: Select the fan film requires hard, smooth, no bubbles, no scratches, peeling paint, paint show, hanging or different color paint mixed phenomenon.

Q:Why does the fan turn?: The electricity is energized and the energy is generated, and the fan leaves the fan moving

Q:How is the fan made up?: he main components of the electric fan are: AC motor. Its working principle is: the coil in the magnetic field force and rotation. Electrical energy is converted to mechanical energy, and, at the same time, due to coil resistance, it is inevitable that some of the electrical energy is converted into heat energy.

Q:Can the electric fan blow to the notebook computer?: The cooling base effect is similar to that of an electric fan, but if one, the air duct will be better. After all, the bottom of the notebook is the air inlet. The best way to get rid of heat is to clean the dust and change the heat transfer cream

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:What are the common faults of electric fans?: In case of abrasion, the blade does not rotate. The easiest part is to replace the parts, especially the shaft sleeve, which is easy to burn if worn.

Q:What is the working principle of an electric fan?: The surface of the body has a lot of sweat, when the electric fan, indoor air flow, so it can promote the rapid evaporation of sweat, combined with evaporation need to absorb a lot of heat, so people will feel cool.

Q:Why not head fan to blow?: The electric fan blowing directly to local head, by cooling the blood flow slowed down, while the other half blood flow in normal operation, the head of poor blood flow, causing brain nerve oppression, brain rich and complex, directly transmitted to the pain receptors, so it is easier to feel a headache.
