Sharing of maintenance tips for AC cooling fans

The AC cooling fan needs maintenance after being used for a period of time, so that it can be used for a long time and its life span can reach the standard. What are the maintenance techniques for AC cooling fans? Ruianpu Electronics will share with you.

The maintenance method of AC cooling fan is as follows:

There are many varieties of AC cooling fans. This article mainly introduces the general-purpose small AC fans used for cooling electronic products. It is widely used in home appliance industry, machinery industry, manufacturing equipment industry and other products with ventilation and heat dissipation requirements. The motor structure of the AC cooling fan uses a shrouded motor, and the rotor and the impeller are fixed and integrated. The air duct is integrated with the positioning frame and the stator. This kind of structure is simple, easy to produce, and very convenient to install and use.

Maintenance tips for AC cooling fans:

1. Open the casing of the device, then turn on the AC 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, then tilt the body to adjust the gap position, and adjust it Then 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 rotated repeatedly until it is clean.

2. The wind speed of the AC cooling fan is determined by many factors. Two important reasons are the bearings of the AC fan.

Ball bearing: Long-term oxidation of the bearing by 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.

Oil-impregnated bearing: AC fan with oil-impregnated bearing mainly relies on the mutual friction between stator and coil to rotate, and the oil in the bearing gradually decreases with the use of the fan, non-stop work and time consumption, so that the fan is used for work When the wind speed is getting slower and slower.

3. The service life of AC fan varies according to different usage environments. Assuming that it works in a standard environment, the life of a general AC ball fan is about 50,000 hours, and the products of different cooling fan manufacturers will also be differentiated. The life of a general AC oil-impregnated bearing fan is 25,000 hours,

4. Due to the repeated rotation of its bearings, wear and tear will shorten the life span, and the life span of high-quality manufacturers will reach 30,000-35,000 hours; the 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.
