WHEN THE VENTILATION FAN BLOCKS YOUR PRODUCTION

WHEN THE VENTILATION FAN BLOCKS YOUR PRODUCTION

Often no one considers that what is located around a cutting and a deburring machine is the problem

The problem gets worse when it is a safety component.

I will try and explain.

When you stand in front of a deburring machine you immediately see the robot, you see the productivity of the machine and its integration with the workers and the production cycle of the company….

It seems that the productivity depends only on the machine and its efficiency.

But it’s not so!

There is a big problem behind the corner.

The machine cannot work if it is not combined with a ventilation system.

And if the ventilation system crashes?
Nobody thinks about the fact that you have to do regular maintenance.

So it happens that the ventilation fan suddenly crashes and you can not work. You can not even produce a piece.
The ventilation system on machines processing aluminium is strictly connected with the machine.
If the ventilation system does not work, the machine stops. If the ventilation system is turned off, there is a high risk of explosion.
It is like an astronaut  going into space.  Until the space suit works as it should…you see only the astronaut, the man who makes the bold enterprise…. When the suit does not work anymore, then you realize that the suit has a fundamental importance.

The ventilation system is your space suit… you have to take care of it!

And it is precisely for this reason that today I have a present for you!

I wanted to ask for your opinion of the first ventilation system expert.

Here he explains to you what you need to look after if you do not want to run out of your space suit….

His name is Diego Perfettibile, but now let us listen to him.

Hi, as Piercarlo has already explained to you, I’m the author of the Ventilazione Sicura blog (www.ventilazionesicura.it).

For more than 11 years I have been busy in industrial ventilation, I project and produce fans that must be installed inside machines you have in your plant.

I know, maybe you’re not even aware of how many machines you have around.

After all it’s NOT your fault.

To avoid trouble with the neighbours, tha fans usually are hidden inside of the anti-noise cabinets.
Often,  who installs the system,  doesn’t give you the right indication and recommendation on the use of the fans.
But this can become a huge problem for you.
If you are not informed about how many fans are in your plant, and especially if you don’t know their  maintenance requirements, you risk sooner or later that a bearing pins itself and iron pieces fly at high speed all around the plant.
Therefore – in addition to the risk of finding  part of the production blocked – you may have to deal with injuries happened to some of your workers.
I’m sure that you do NOT want to find yourself for any reason in this sitution, right?

Here, therefore,  are 2 simple tricks to avoid the risk of unplanned downtime, ensuring  the safety of your  workers.

These are two – simple and easy – maintenance activities, which always allow you to keep your ventilation fans in excellent health.
With a little grease everything works smoother.
Each fan has a bearing that allows the impeller to rotate. The smaller machines have only the  motor bearings, which are usually  lubricated for their entire machine  life. (That means you do not have to add any lubricant, but to replace them when their machine life is finished.)
While the bigger fans, on the other hand, also have bearings supporting the fan shaft.
The manufacturer (if he is serious) should have written – on a plate placed on the machine – how much, how often and which type of  grease is required.

If you are thinking:
“Now I’ll go and grease the bearings and for the next two years they will be ok”
I’m really sorry to disappoint you, but it does not work in that way.
Indeed, you NEVER have to exaggerate with the grease in the bearings.
First because  the amount you put in will be immediately rejected, so you will only waste time and money.
Moreover, an excess of lubricant can overheat  and pin the bearing.
Avoid unleashing an earthquake in your plant.
Fans – like any rotating machine – are machines that generate vibrations.
When they have just been produced, completely new, if you measure with some sensors the vibrations on the bearings, you will have some values different than zero.

Furthermore, over  time the values will increase, until you reach levels that erode the impeller.

For it is for this reason that it is necessary that you check regularly how much your fans vibrate.
Thanks to these preventive measures you can find the right moment to proceed with the balancing and bring the values back to the correct vibrations.

It is the same thing that you have to do with you car tyres.
In fact if you notice that on the rims there are little weights, which reduce almost to zero the vibrations that otherwise would shake your car too much.

How can you measure the fan vibrations?

There are some special devices, one has also to know how to use them. If you have no worker able to perform this kind of control, you can call a supplier.
Many of my clients – as they had no time and trained workers to control the vibrations –  asked me to do this kind of activity. Every six months one of my engineers would go to my client to measure the vibrations and – as he on the spot –  do a check-up of all the machines.
As you now know these two simple tricks in order to keep your fans in perfect condition, all you have to do is to put them into practice. (Start tomorrow, I recommend it).

If you want to find out how to make a real maintenance plan for your fans, making sure that your production lines run continuously, well I’ve a present for you.

I have written a very practical guide for non-experts, in which you can find everything you need in order to defeat those irritating sudden occurrences of fan failure, and avoid  spending  a lot on  spare parts and repairs.

Well, goodbye for now and  I’ll pass the line to Piercarlo.

I had a meeting with Diego and personally studied  the importance of what I have just written
