The maintenance method of AC cooling fan is as follows:
There are a wide variety of AC cooling fans. This article mainly introduces the general small AC fans used for cooling electronic products. It is widely used in household appliances industry, machinery industry, manufacturing equipment industry and other products with ventilation and heat dissipation requirements.
The motor structure of the AC cooling fan is a cover motor, and the rotor and impeller are fixed. The air duct is integrated with the positioning frame and stator. The structure is simple, easy to produce, and convenient to install and use.
Maintenance skills of AC cooling fan:
1. Open the shell of the equipment, then turn on the AC fan, turn off the power supply of the equipment, and blow the fan at a distance of 2CM from the fan with the air gun; Then use industrial alcohol to wipe the dirt on the fan blades, then tilt the machine body to adjust the clearance position, and 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, it needs to be cleaned, and then rotate repeatedly until it is clean.
2. The wind speed of the AC cooling fan is determined by many factors. The two important reasons are the bearing of the AC cooling fan,
Ball bearing: the long-term oxidation of air ions on the bearing and the accumulation of dirt and dust will lead to the increase of the friction resistance of the bearing, resulting in the gradual decrease of the fan speed.
Oily bearing: the AC fan with oil-bearing mainly rotates by the mutual friction between the stator and the coil, while the oil in the bearing gradually decreases with the use of the fan, the continuous work and time consumption, resulting in the slower wind speed when the fan is used for work.
3. The service life of AC fan will vary according to different use environments. Assuming that it works in a standard environment, the general service life of AC ball fan is about 50000 hours, and the products of different cooling fan manufacturers will also differ. The service life of the general AC oil-bearing fan is 25000 hours,
4. Due to the repeated rotation of its bearings, wear will shorten the service life, and the service life of high-quality manufacturers will reach 30000 to 35000 hours; The equipment needs to be cleaned at least once a month. The air inlet net should be kept clean to prevent blocking the air flow. It can be cleaned with a soft brush or compressed air.
