Using Machine Criticality
to Determine Inspection
Frequency
Once it has been concluded that a
machine is critical enough to warrant
the cost of monitoring its condition,
the next step is to establish how of ten
it should be inspected. A number of
factors should be considered. Check out
this article on the ML site to see how
inspection frequency can be determined
by measuring how close the machine is
operating to alarm limits.
The Truth About
Additive Depletion
In oil analysis, additive depletion is often
used to estimate the remaining useful life
of the oil. Laboratories can employ various
methods to track the depletion of addi-
tives. Access this 4-minute video to find
out what the two main types of additive
depletion are and why it is important for
additives to deplete in order to save the oil,
the machine or both.
How Color Can Indicate
Grease Quality
The color of grease can provide some
indication of its overall quality. As grease
degrades and becomes contaminated, it
usually will begin to darken. A shift in color
could also be a sign that the grease has
mixed with a different type of grease. Read
this article on the ML site to understand
while the color of grease may have the
potential to provide quality information, it
is only intended as a branding to indicate
the type of grease.
Identifying Water
Contamination in Oil
Water is known to be very damaging to
oil and machines. It is often referred to as
the second most destructive contaminant.
Access this 1-minute, 51-second video to
discover the different states of water in
oil so you can recognize its presence and
determine where it is coming from and how
to remove it.
Causes of Hydraulic
Pump Failures
The hydraulic pump
is generally the most
expensive component
on a hydraulic system.
It has the highest
reliability risk, the
highest contaminant
sensitivity risk and the
ability to cause chain-reaction failures. In
other words, when the pump starts to fail,
it starts to kick out debris into a debris field
downstream of the pump. Learn which
factors can cause a hydraulic pump failure
by reading this article on the ML site.
