| Sure
it's easy to see the difference between used and new vacuum pump oil, but
we decided to take it a step further. After all, the old saying that 'seeing
is believing' has usually proven to be true. Below is a look at our simple
test comparing the old vacuum pump oil removed from the vacuum pump we've
been working on. It's compared to new vacuum pump oil. |
| Vacuum
Pump oil - take a closer look!: |
| The
photo on the right shows old vacuum pump oil (left side in the photo) removed
right after our micron vacuum test. For comparison, a sample of new pump
oil is shown on the right. Of course the used oil is darker and we've
already seen what other contaminants (dirt and debris) that it contained,
so we decided to take this simple test one step further. |

| Is
that UV Dye? |
Using
a UV LED light
we quickly saw that the used vacuum pump oil contained other contaminants
that we not visible to the naked eye. However, it's not really surprising...
being that almost every system out there has some dye in it. |
Seeing that a suspected 'good' vacuum pump had a lot of visible
contaminants in the old oil, we decided to double check for other contamination.
With low lighting we used a
UV LED light
to see if there was anything else in the oil. We can't say for sure that
the used oil is fluorescing because of UV dye, but it certainly is fluorescing!
We didn't do any scientific tests, but it's pretty simple to reason that
it's probably dye drawn in form a system. So how contaminated is your
vacuum pump oil? |
