In our life, cooling fans are unfamiliar to us, especiallyCooling fan DCIt is widely used in equipment. The cooling fan sometimes shakes when it is used. What causes this? What effect does shaking have on the cooling fan?

      The vibration and vibration of the cooling fan may be caused by the following reasons: the quality problem produced by the cooling fan manufacturer or the purchase of relatively cheap raw materials, or the looseness of the stator and rotor may be caused by falling, impact and violent handling during the transportation process. Also pay attention to the roughness of the fan blade surface and the lack of dynamic balance test for the mold fineness. One of these reasons can cause the cooling fan to shake.

      If the cooling fan shakes seriously after being used for a period of time, the cooling fan is not cleaned and maintained properly after being used for a long time, and the cooling fan dust is accumulated, and the fan blade has been damaged due to the impact of debris during operation. In addition, when installing, the four corners of the mounting screws are not the same or the four corners are not in the same plane, which causes the installation of the cooling fan to slightly change its center, and the vibration of the cooling fan will affect its service life and mute effect.

      How to check the cooling fan vibration:

1. Remove the cooling fan first. The small cooling fan can be fixed with one hand, and the large cooling fan can be fixed with two hands, which is dangerous to some extent. Non-professional personnel should not test. If the vibration and vibration of the removal test are significantly improved, consider whether the installation angle and installation method are correct.

2. When the shaking and vibration of the cooling fan test remain unchanged, the frame and fan blade should be checked for shaking. If it is possible that the bearing is damaged, it cannot be used anymore and needs to be replaced. Here, the longer and more durable ball bearing is recommended.

3. If the above two conditions cannot be thrown out, dust and impurities of the fan and the ventilation pipe shall be cleaned to confirm that the installation is correct. If there are still faults, the quality problem or poor quality of the cooling fan shall be considered.
