AC cooling fan after a period of time is required to carry out maintenance, so that it can be used for a long time, the life expectancy can reach the standard. AC cooling fan maintenance what skills it, can Jen electronic to share with you.
AC cooling fan maintenance methods are as follows:
AC cooling fan of many varieties, here mainly introduced for electronic products cooling, general purpose small AC fan. Widely used in the appliance industry, machinery industry, manufacturing equipment industry and other products with ventilation and cooling requirements.
The motor structure of the AC cooling fan is a cover-level motor, the rotor and impeller are fixed in one piece. The rotor and impeller are fixed in one piece, and the air guide and positioning frame and stator are integrated. This structure is simple, easy to produce, installation and use is also very convenient.
AC cooling fan maintenance tips:
1. Open the shell of the device, and then open the AC fan, turn off the power supply of the device, with a wind gun from the fan at 2CM, blowing the fan; followed by industrial alcohol to wipe the fan blade above the dirt, and then tilt the body to adjust the gap position, adjusted, and then use the wind gun to blow out the dust in the device. From the front of the device to the back of the device, all need to clean, and then turn repeatedly until clean.
2. The wind speed of the AC cooling fan is determined by a variety of factors, the two important reasons are the bearings of the AC wind dissipation.
Ball bearing: air gas ions long-term oxidation of bearings, dirt dust accumulation, will lead to increased resistance to wear bearings, resulting in a gradual decline in the speed of the fan.
Oil bearing: AC fan with oil bearing mainly relies on the mutual friction between stator and coil to rotate, and the oil in the bearing, with the use of fan, non-stop work and time consumption, gradually decreases, resulting in the fan to work, the wind speed is getting slower and slower.
3. AC fan life according to different use of the environment will have different differences, assuming that the standard environment work, the general AC ball fan life of 50,000 hours or so, different cooling fan manufacturer’s products will also have distinction. General AC oil bearing fan life of 25,000 hours.
4. Because of its bearing repeated rotation, wear and tear will shorten the life, high-quality manufacturers life will be to 30,000-35,000 hours; equipment needs to be cleaned clean, at least once a month. The air inlet screen should be kept clean to prevent blockage of airflow, either by cleaning with a soft brush or by compressed air.
