[AC fan] The secret of longevity

There are many varieties of AC fans, and each type is used differently, but the secret to their longevity is basically the same. u003cbru003e1. Open the casing of the device, then turn on the fan, turn off the power of the device, use the air gun to be 2cm away from the fan, blow the fan; then wipe the dirt on the fan blade with industrial alcohol, and then tilt the body to adjust the gap position. After adjusting, use the air gun to blow out the dust in the equipment. From the front of the device to the back of the device, it needs to be cleaned, and then rotate repeatedly until it is clean. u003cbru003e2. The wind speed of AC fan is determined by many factors. The two most important reasons are the bearings of AC fan u003cbru003e2.1. Ball bearing: The long-term oxidation of air ions in the air and the accumulation of dirt and dust will increase the friction resistance of the bearing and cause the speed of the fan to gradually decrease. u003cbru003e2.2. Oil-impregnated bearing: AC fan with oil-impregnated bearing mainly relies on mutual friction between the stator and the coil to rotate, and the oil in the bearing gradually decreases with the use of the fan, continuous work and time consumption. When the fan is used for work, the wind speed becomes slower and slower. u003cbru003e3. The service life of the fan varies according to different use environments. Assuming it works in a standard environment, u003cbru003e3.1. The life of the general AC ball fan is about 50,000 hours, and the products of different manufacturers will also be differentiated: the life of the products of manufacturers such as German EBM, Taiwan SUNON, NIDEC, Wenling Tongyi, Wenling Yongyechang, etc. will be 5 10,000-60,000 hours; u003cbru003e3.2. The lifespan of a general AC oil-impregnated fan is 25,000 hours. Due to the repeated rotation of its bearings, wear and tear will shorten the lifespan, and the lifespan of excellent manufacturers will reach 30,000-35,000 hours; u003cbru003eThe equipment needs to be cleaned, at least once a month. The air inlet net should be kept clean to prevent blocking the airflow. It can be cleaned with a soft brush or compressed air. u003cbru003eAC fans are widely used in the home appliance industry, machinery industry, and manufacturing equipment industry. Therefore, it is necessary to spend some time on the protection of equipment. This problem cannot be ignored.
