Why Do Axial Fans Make Noise During Use?

Why Do Axial Fans Make Noise During Use

During the use of the axial fan, once excessive noise is generated, it will affect the surrounding environment.

What are the reasons for the noise? Let’s introduce the reasons and solutions for the noise caused by axial fans:

A: Discrete noise generated by the fan:

This is mainly related to the rotation of the impeller, especially when the fan is at a high speed and low load, it is easy to generate this noise.

The appearance of discrete noise is due to the asymmetry of the structure around the blade and the abnormal design of the blade orifice, resulting in an uneven flow field around it.

Generally speaking, discrete noise has the following three situations:

Because of the metal mesh cover or front guide vane installed in front of the air inlet, the air intake is obstructed and noise is caused.

The blades are rough or not piled up, causing the fan to appear rotating frequency noise.

The axial fan has a rear guide vane, which causes noise at the exit.

B: Fan vortex noise:

This kind of noise is often caused by the separation vortex generated when the air flows.

Specifically, it has the following four reasons:

When the turbulent airflow flows to the blades, it will cause turbulent flow noise.

When the airflow passes through the surface of the blade, the turbulent boundary layer noise is generated due to the relationship of the turbulent flow attached to the surface layer.

The turbulent surface layer on the blade surface falls off at the trailing edge of the blade, which further causes detachment vortex noise.

During the operation of the axial fan, because the pressure of the convex surface is lower than the pressure of the concave surface, the secondary flow from the concave surface of the blade tip to the convex surface is taken away, resulting in top vortex noise.

Why the Axial Fan Will Wear Out?

Why the Axial Fan Will Wear Out

Once the axial fan is worn out, it will cause the fan to vibrate when in use, which will seriously affect the service life of the axial fan, and even cause the axial fan to fail to work in severe cases.

Among them, blade wear is a relatively common wear condition.

The wear of the blade will cause fluidity inside the axial fan, which will cause the blade to break and run away.

Therefore, it is important to understand the reasons for axial fan wear to prevent the wear situation in advance.

The main reasons for the wear of the axial fan are as follows:

Axial fan wear and tear caused by dust

During the operation of the axial fan, a large amount of microscopic dust will accumulate for a long time and cause damage to the fan bearings, blades, and motors.

Due to the small particle size and numerous types of dust, many specks of dust cannot be effectively eliminated.

These are easy to form damage on the vulnerable parts of the axial fan.

At the same time, some axial fan users reduce the application of fan dust collectors to control costs and improve the ventilation effect of the axial fans.

This will cause strong damage to the fans by dust and increase the risk of fan wear and failure.

The operating conditions are unreasonable.

The using environment of the axial fan is different, then the required functions are different, which leads to the need to adjust the parameters of an axial fan when the axial fan is used to adapt to the operating conditions.

In particular, the actual operating conditions are more complicated, which is very different from the design of the axial fan manufacturer, which will affect the actual use of the fan, resulting in overload operation and accelerated wear of the axial fan.

Running speed is too fast.

The running speed of the axial fan is too fast, which is also one of the main causes of wear.

According to the information provided by many customers, once the axial fan runs faster, the wear is more serious, especially under high-temperature conditions.

The operating conditions of the axial fan are unreasonable

Different positions and different function settings require different axial fans and different state adjustments to adapt, and the gap between design and actual, functions and needs have formed the problem of fan selection.

It is very easy to cause the problem of fan overload work and aggravated fan wear.

The above 4 points are the main reasons for the wear of the external axial flow fan.

Of course, in actual research and use, other reasons cause the wear of the axial fan.

When a wear failure occurs, a comprehensive inspection is required to eliminate the fault.

Factors Affecting the Use of External Rotor Axial Flow Fan?

Factors Affecting the Use of External Rotor Axial Flow Fan

Nowadays the use of external rotor axial fan many occasions, we are using the equipment, we hope it can be stable operation, without any failure and problems.

But, in the actual application, many factors will affect its use, the following looks at the specific factors.

External rotor axial fan and the ordinary fan compared to the reason it is called “axial flow” is mainly because the axis of the blade with the direction is different, the airflow parallel to the fan axis flow.

Several factors reduce the performance of external rotor axial flow fans.:

Equipment in the start, can not start normally. If the start time is too long, it may be the external rotor axial fan motor can not start normally, or the rated power of the motor is not enough. If the axial motor rotor failure or friction serious will also affect the fan start.

The size of the air volume will also affect the use of the external rotor axial fan because the size of the air volume is directly related to the ventilation effect.

The air volume of the external rotor axial fan and the size of the air blade, speed, etc.

The use of the environment will also affect the use of the external rotor axial fan, such as air density, altitude, temperature, and so on, generally speaking, the equipment on the use of environmental conditions are required.

If the environment is harsh, more than the equipment should bear the range, it may shorten the service life of the fan, so the special use of the environment should be used to customize the fan.

Many factors are affecting the use of the external rotor axial fan, which are not only the reasons for the equipment itself, also the factors of the external environment.

In any case, during the use, should be used under more standard requirements.

So that not only can make the equipment run efficiently, but also can extend the service life of the external rotor axial fan.
