A Wobbly Fan is Bad for Business

 
Here at Industrial Cooling Solutions Inc., we have a lot of experience when it comes to cooling tower fans. For the vast majority of industrial cooling towers, fans are used as a way to ensure that as much heat as possible is mitigated while also helping to reduce the rate of evaporation present within the tower itself. Unfortunately, because these fans are in a near constant state of rotation, issues can pop up. Although the average person doesn’t put too much thought into it, circular rotation is not as easy to accomplish as one might think. Centrifugal force can place a large amount of stress on these fan assemblies and, if left to their own devices, these fans can and will spin themselves into oblivion. In today’s post, we are going to go over some of the ways that you can make sure that your cooling towers fan is set up for success and ways you can reduce the amount of wobble present in your fan assembly. Continue reading below to learn more.
 

Why Does the Wobble Matter?

 
First things first, we think it is important to explain exactly what we mean when we use the term “wobble.” If you have every had an unbalanced ceiling fan, you probably already realize how bad a fan can start to wobble when it is not setup correctly or it is damaged. This same idea can be applied to fans in industrial cooling towers, however, with these particular types of fans, we aren’t so much worried about the wobbling so much as we are worried about the vibrations that cause the fan to wobble. Vibrations, even small ones, can cause fans in industrial cooling towers to perform poorly and, in some extreme cases, they can even cause damage to additional components within the tower. So, what should you do to help mitigate vibrations and ensure that your fan is working as well as possible? Read below to find out.
 

  • Balance: Like The Force, fans in industrial cooling towers are all about balance. These fans rotate at such high speeds that even a slight variation in the balancing of the fan blades can have tremendous effects on the fan assembly as a whole. If one fan blade is unbalanced, it will place stress on the other fan blades through vibrational forces which, over time, can compromise the entire system including the motor that drives the fan and the drive shaft that transforms mechanical energy into rotational force. If you’ve noticed that a fan in one of your cooling towers is underperforming, take the time to make sure that the blades are balanced. A small adjustment now could save a lot of time and energy in the future.  
  • Damage: In industrial cooling tower applications, fans are used to push large quantities of air through the top of the tower or, in some cases, are used to pull large amounts of air into the tower. If a fan blade becomes damaged, it can affect the way that the air flows over the entire fan assembly and, if not caught quickly, can lead to quite a bit of damage. Even a small knick in a single fan blade can be enough to disrupt the airflow to the point that it starts to cause vibrations to occur. As we stated earlier, vibrations are never a good thing when it comes to fan assemblies. To help reduce the chances that this will happen, we suggest that you inspect the blades of your cooling towers fans on a regular basis to ensure that they have not become damaged in some way.

 
We hope that this blog has been informative and that you have gained a little more knowledge about the importance of a stable fan in your industrial cooling tower.
