The Sampling
Process
Trend Analysis
A single sampling analysis is useful in providing information
when critical failure conditions exist. However, trend analysis
is a better tool for estimating the useful life or overall
condition of your engine or equipment. Trend analysis samples
are taken and analyzed at regularly scheduled intervals.
Comparing the most recent analysis to previous reports on a
given machine shows the development of trends. Monitoring these
trends enables early detection of internal abnormalities. Tested
values falling within acceptable limits may show a pattern of
subtle variance, which could signal a developing problem.
Machines of the same type will
accumulate contaminants and wear at different rates. Performing
trend analysis on each machine is the most effective method of
giving you an internal look at your equipment and enabling you
to deal with developing problems before they become catastrophic
situations.
Sampling Frequency
The frequency of sample analysis from your equipment depends on
the machine type, machine application and condition, operating
environment and other variables. For example, many machines that
operate in harsh environments, such as heavy equipment in mining
or construction, require short oil sampling intervals - every
100 to 300 operating hours. However, certain power transmission
systems, such as gearboxes and hydraulic systems used inside
manufacturing and production facilities, require no more than
quarterly sampling intervals. The following table lists generic
sampling frequencies for common equipment types, and is provided
as a guideline only. Additional information is available from
Oil Analyzers Inc., your lubricant supplier, and the equipment
manufacturer.
Collecting a clean and
representative oil sample is critical to the oil analysis
process. Put simply, an oil analysis is only as good as the
sample taken. The accuracy and reliability of the data produced
by an analysis hinges on receiving a representative sample from
the equipment to be tested. To assure that the sample extracted
is representative of the system, always follow proper sampling
procedures.
