How to check the fan
Fans are commonly used electrical equipment in daily life. Whether it is a household fan, a computer cooling fan or an industrial fan, it is important to check its operating status regularly. This article will give you a detailed introduction to how to check the fan, and provide hot topics and hot content in the past 10 days for reference.
1. Basic steps for fan inspection

1.Check power connection: Make sure the fan's power cord is intact and the plug is in good contact with the socket to avoid the fan being unable to start due to power problems.
2.Observe fan blades: Check the blades for deformation, cracks or dust accumulation. Damaged or dirty blades will affect the fan's balance and cooling effect.
3.Listen to the running sound: The sound of the fan in normal operation is uniform. If there is abnormal noise (such as friction, buzzing), it may be that the bearings are worn or the blades are loose.
4.Test speed: Gently move the blades with your hands to check whether they rotate smoothly. After powering on, observe whether the speed is stable. If it is fast and slow, it may be a problem with the motor or circuit.
5.Check motor temperature: After running for a period of time, touch the motor shell with your hands. Overheating may mean that the motor is overloaded or has insufficient lubrication.

3. Fan common problems and solutions
1.The fan does not rotate: It could be a power problem, a damaged motor or a faulty capacitor. It is recommended to check the power supply first, then test whether the capacitor is intact, and replace the motor if necessary.
2.The fan is noisy: Usually caused by dust accumulation on the blades, lack of oil in the bearings or loose screws. Cleaning the blades and adding lubricant can effectively alleviate the noise.
3.Fan speed is slow: It may be due to insufficient voltage, aging capacitor or motor wear. Check whether the voltage is stable and replace the capacitor or motor if necessary.
4. Fan maintenance tips
1.Regular cleaning: Clean the fan blades and grille at least once a quarter to avoid dust accumulation that affects performance.
2.Lubricate bearings: Add lubricating oil to the fan motor bearings once a year to reduce friction loss.
3.Avoid long-term high-load operation: Continuous use of the fan in a high-temperature environment will shorten its life. Intermittent use is recommended.
Through the above steps and precautions, you can easily check the operating status of the fan and solve the problem in time to extend the service life of the fan. If the problem cannot be solved by yourself, it is recommended to contact professional maintenance personnel.
