In recent years, the technology and performance of the cooling fan has reached a mature stage. Many factories use it to dissipate heat from various mechanical equipment, but due to various reasons, some failures occur during use. Then, let's introduce the common faults of cooling fans.
In recent years,Cooling fanIts technology and performance has fully reached a mature stage, many factories use it to heat all kinds of machinery and equipment, but due to various reasons, it has some failures in the process of use. Then, let's introduce the common faults of cooling fans.
Common faults of cooling fan are:
1. When the cooling fan rotates during use, sometimes you hear the sound of "da da da" collision, but sometimes there is none. It turned out that the data lines and power lines were densely scattered in the cooling fan. Sometimes the line ends touched the fan blades of the fan, which caused abnormal sound when the cooling fan rotated.
Solution: Bind the data line and power line in the half fan such as rubber band and adhesive tape paper to avoid passing above the cooling fan.
2. There is also a failure phenomenon of the cooling fan. The cooling fan was used normally in the early stage, but it was suddenly found that the fan automatically moved to a fixed position in the near future. After investigation, it was originally due to the failure of the fastener of the fixed radiator and the resonance phenomenon caused by the rotation of the fan., Resulting in fan displacement.
Solution: replace the new buckle.
3. The cooling fan suddenly emits a characteristic noisy noise when in use, even louder than the sound emitted by the chassis power supply. This is because the surface of the cooling fan and the gap of the radiator have gathered too much dust. The motor oil of the fan has completely dried up, so it has caused the roar of the motor.
Solution: We can separate the cooling fan and the radiator first, and the radiator can be cleaned directly with tap water. Wipe the cooling fan with soft paper first, and the gap can be wiped with a medical label. Turn on the plastic sticker of the fan and drip one to two drops of ordinary sewing machine oil into the movement.
4. If some cooling fans use less than a week, there will be excessive noise and poor rotation. The speed of the fan is relatively slow when it is turned on, and the noise is relatively large. After a period of time, it will return to the normal state. The reason for this situation is that the indoor temperature of the cooling fan is generally low, resulting in the rotation of the bearing Lubricating oil fails.
Solution: add antifreeze lubricating oil to the cooling fan, and pay attention to the temperature of the environment, and pay attention to its maintenance.
There are many reasons for the failure of the cooling fan, so it should be maintained during use, so as to extend its service life.
