1、工业风扇长期运行后，里面的轴承缺乏润滑油导致出现噪音，只需要滴上润滑油即可解决。
2、目前市面上有些工业风扇厂家为了节省成本，扇叶采用了便宜的材料，而且制造时技术不达标，出现了“偏心”现象，风扇运行一段时间后，“偏心”越来越严重，慢慢的就会有噪音出现，这个需要企业购买工业风扇时自行分辨。
3、风扇长期运行过程中，扇叶与叶柄中间的减震垫出现了磨损，有了间隙产生了噪音，这时候我我们只需要更换减震垫并上紧螺丝即可解决问题。
4、工业风扇的电压愈高，其转速升高，振动就愈大，产生的噪音也愈大，构成风扇的零件设计，也会影响噪音程度。这时只需考虑绕线铁心的尺寸，扇叶与外框的设计及准确的制造与平衡。
如果还是有噪音的话，可以联系本公司，我们将竭诚为您服务！
1. Industrial fans run for a long time, the bearing inside the lack of lubricating oil led to noise, just need to drop lubricating oil can be solved. 2. At present, in order to save costs, some manufacturers of industrial fans in the market use cheap materials, and manufacturing technology is not up to standard, there has been "eccentric" phenomenon, fan operation for a period of time, "eccentric" more and more serious, gradually there will be noise, this need to buy their own industrial fans to identify. 3. During the long-term operation of the Fan, the damping pad between the Fan Blade and the blade handle appears to be worn, and there is a gap that generates noise. At this time, we only need to replace the damping pad and tighten the screws to solve the problem. 4. The higher the voltage of the industrial fan, the higher the speed, the greater the vibration, and the greater the noise. The component design of the fan also affects the noise level. At this point only consider the size of the wound core, Fan and frame design and accurate manufacture and balance. If there is still noise, you can contact the company, we will serve you wholeheartedly!
