Industrial fan can promote a large amount of air movement with greater efficiency, produce super large air volume, make the space form movement and circulation airflow field, and effectively control the air circulation problem of industrial production workshop. The following Jiaxing Road and for you to sort out the purchase of industrial fans need to pay attention to what aspects, I hope to help you.


Purchase of industrial fans


1: Check whether the motor head and the whole machine part of the industrial fan vibrate when the industrial fan rotates at low and medium speed, especially at high speed. At the same time, carefully listen to whether the motor head part of the industrial fan has any other abnormal noise (except wind noise), and whether the noise of the industrial fan is within the acceptable range.


2: After a long time of high-speed rotation (at least 1 hour later), the industrial fan motor can feel the heat of the front shell by hand or other appliances. If it is very hot, it indicates that the heat dissipation performance of the industrial fan motor is poor. In the long-term use of the motor, the high temperature rise will easily cause the industrial fan to stop rotating or burn the motor


3: Look at the speed, power, air volume, noise and other parameters of the industrial fan (theoretically, the speed, power, air volume and noise of the industrial fan are in direct proportion, that is to say, the higher the speed of the industrial fan, the greater the power, the greater the air volume, the greater the noise, and the better the cooling effect of local ventilation. However, the speed, power, air volume and noise of different brands of industrial fan manufacturers are different There is a big gap in the measurement of air volume, noise and other parameters. In fact, it is difficult to make a horizontal accurate comparison. We can only feel it according to our life experience.


4: See if there is intermittent pause when the industrial fan rotates left and right swing head at high speed, and if there is swing head not in place.


5: Safety performance: check whether the front and rear nets of the industrial fan adopt the dense net design, and whether the overall structure of the product is reasonable (the industrial fan with dense net design has higher safety performance in use); ask whether the industrial fan is equipped with overheat protector, and whether it will automatically power off when the industrial fan motor is accidentally stuck.
