Can all contaminants be seen with naked eyes?

In part 2 of the know your oil series, we will discuss?Particle Contamination. Whenever we talk about contamination the first thing that comes to our mind is solid particles that we can see or feel. But what we do not understand is how big a particle can cause wear and tear to your machines. Can all contaminants be seen with naked eyes? Is it too late to wait until then?

To answer the above questions we must first understand the actual clearance size of the different types of lubrication film formed between?rolling?and?rotating?components which are essential for providing proper lubrication. Oil film thickness in machinery is measured in microns (μm), or one-millionth of a meter.

Below are the finest tolerance found in different types of components.

When tiny particles, which cannot be seen through human eyes, pass through the critical machine parts under load, they create small microtears which get transformed into cracks over some time due to continuous stress and strain conditions leading to the more fine generation and hence increase contamination.

The contaminants that are considered to be most damaged are from size 2 to 20 μm and avoiding these are key to keeping your?machinery breakdown free.

But it is also essential to understand when to call the?oil clean?and when dirty, as it is understood that changing oil frequently and maintenance every time is not feasible.

The below chart shows us what particle levels are admissible and what harms our system.?

But knowing this is not enough if we don’t know when to get?oil sampling and testing?done. The below chart provides an estimation for testing and the type of test to be conducted.
