What should I do if there is abnormal noise soon after using the high pressure fan? I believe that friends will also encounter such a thing. Today Zibo Yinfeng Fan Co., Ltd. will talk with you about why the high-pressure fan has abnormal noise.
We know that the high-pressure fan is mainly composed of a drive motor, a volute, a blade, an inlet and an outlet. Generally, after the assembly is completed, it will be strictly tested before leaving the factory. Appeared, so we can know from the structural analysis:
1. The suction performance of the high-pressure fan causes the foreign matter to be damaged instantly when the foreign matter is sucked in
Because the clearance between the wind blade and the volute is very small, about 0.2 to 0.5mm, if not properly protected, 100% of the foreign matter will be sucked in, causing friction between the wind blade and the volute, which will cause abnormal noise.
2. The drive motor oil seal (bearing) is damaged
The general bearing structure determines the service life, and the middle is lubricated with grease. When it is used for a period of time, the service life is exceeded, or the bearing gap is too large, it will cause abnormal noise of the motor.
So how to solve the abnormal noise of the high-pressure fan?
A. If there is an abnormal sound in the volute, you can remove the 8 screws on the front cover of the volute, and visually check the surface of the blade and the volute for foreign objects and traces of friction. Check the position of the traces, and then use sandpaper. Carry out a sanding process. Then install them in order.
B. If the bearing is damaged, it is relatively troublesome. To dismantle the whole machine, remove the motor in order by the corresponding tool, replace the bearing, and then install the machine in turn.
If it is inconvenient, it is best to consult the relevant professional manufacturers or return to the factory to solve it. If the conditions are inconvenient, the above method can solve the abnormal noise of the high-pressure fan.
Fan noise is generally reduced by using a muffler. High-pressure fans generally use filters to prevent foreign objects from entering the fan casing and causing abnormal noise.
