The meaning of Frequency conversion in Axial flow Fan and its function in Transformer

Jan 26, 2018

1. Can an axial fan be used to exhaust smoke? In addition, how to avoid the problem of excessive noise in the process of use?

In the fire fighting system, it can be said that smoke exhaust is an important job. At present, the axial flow fan is used more, so it is no problem to use the axial flow fan on the exhaust smoke, and it has a good use effect. However, we need to pay attention to the problem of selection, because only when the selection is correct, can it be used smoothly.

In order to avoid the problem of excessive noise in the process of using axial fan, the key is to strictly control the parameters of fan. Because the fan parameters are proportional to the noise. Moreover, the flow channel should be optimized so that the noise of the axial fan can be controlled well by these two measures, thus avoiding the above problems.

2. What is the role of axial fan in transformer? In addition, is there a warranty period for the fan manufacturer?

In the transformer, if the axial fan is used, it can play a role in cooling the auxiliary transformer coil and core. Therefore, it is a cooling equipment. The axial fan product, which has a warranty period, is 18 months after shipment, or 12 months after installation, that is, one year. However, some manufacturers are for several years.

3. What specially refers to for the frequency conversion in axial flow fan?

Frequency conversion in axial flow fan refers to changing the frequency of power supply, which plays a certain role in regulating the load. In this way, the power consumption can be reduced, the loss can be reduced, and the service life of the fan can be extended. And its representative installation equipment, is for the frequency converter. And, uses in the axial flow fan, has the certain benefit.http://www.jnblower.com/
