Although the industrial ceiling fan is an industry that has only emerged in recent years, it has become a sharp tool for summer cooling and ventilation in many industries, especially in tall and large industrial plants, logistics and storage, waiting rooms, stadiums, and exhibition halls. Compared with the traditional cooling method, the large industrial fan can push a large amount of airflow to the ground, thereby forming a certain height of airflow layer on the ground to move horizontally, promoting the overall air circulation to achieve the effect of cooling and ventilation. Large industrial fans will inevitably produce a certain amount of noise during operation, but don't panic. It does not mean that noise is a malfunction. Today, the editor will come to talk to you about the sources of noise in the operation of large industrial fans?
The operation of any kind of machinery and equipment will produce noise, even our computer case will have "big" noise, not to mention the huge industrial fan? Therefore, you must not be overly alarmed when you hear the noise of a large industrial fan, and calmly inquire about the source of the noise and analyze the cause. So how to query and analyze it?
In fact, there are three main sources of noise in the operation of large industrial fans, namely wind noise, vibration and abnormal noise. Let's discuss these three types of noise together:
Wind noise: Wind noise is mainly caused by the pulsation of the pressure distribution on the blade caused by the gas flowing through the blade when the large industrial fan blade is in operation. In fact, the wind noise generated by the floor fan used in our family is the same principle, and the greater the air volume of the large industrial fan, the greater the wind noise.
Vibration: Industrial large fans will inevitably produce vibration when they are running, but the noise caused by vibration is generally not very large.
Abnormal noise: The sound produced by wind noise and vibration is completely different from the abnormal noise. If it is found that there are other noises in addition to the sound produced by wind noise and vibration when the large industrial fan is running, it is likely to be the large industrial ceiling fan Some parts have failed.
