Open the shell of the equipment, then turn on the fan, turn off the power of the equipment, blow the fan with the wind gun 2CM from the fan, then use the industrial alcohol to wipe the dirt on the fan blades, then tilt the fuselage to adjust the clearance position, then use the air gun to blow out the dust in the equipment From the front of the equipment to the back of the equipment, need to clean, and then repeatedly rotate until clean and clean.
Second, the wind speed of the AC fan is determined by a variety of factors, the most important two reasons, is the AC fan's bearing
2.1, ball bearings: air ions long-term bearing oxidation, dirt and dust accumulation, will lead to the friction of the bearing increased, resulting in a gradual decline in the speed of the fan.
2.2, oil bearing: Oil Bearing AC fan, mainly by the stator and the coil friction between the rotation, and the bearing of the oil, with the use of the fan, non-stop work and time consumption, gradually reduced, resulting in the use of wind turbines work, wind speed more and more slowly.
Third, fan life according to different use environment will have different differences, assuming that the standard environment to work,
3.1, the general AC Ball fan life of 50,000 hours or so, different manufacturers of products will be differentiated: Germany EBM, Taiwan Sunon, Nidec, Shenzhen winner, Shenzhen Yong Chang and other manufacturers of product life expectancy in 50,000-60,000 hours;
3.2, the general exchange of oil-bearing fan life of 25,000 hours, because of its bearing repeatedly rotating, wear will shorten life expectancy, high-quality factory life will be 30,000-35,000 hours;
The equipment needs to be clean and clean, at least a Times a month. The air inlet should be kept clean to prevent airflow and can be cleaned with a soft brush or compressed air.
