Bewildering Oil Analysis Results
Ian Broad, Filtration Sales, Wyko Industrial Supplies
1. Check the filter housing have elements in them and
that they are the correct rating.
2. Check the filter manufacturer/supplier has not been
changed and that inferior filters are being used without
your knowledge
3. Check that the housings are not on bypass for any
reason.
4. Check any top ups are being done thro filter trollys.
5 Check any off-line filtration is still being carried
out.
If any of the above are not as they should be and correct
and retest.
6. Test method, check that there has been no change in
the test method or sampling procedures, dirty bottles,
tubes sample position, storage, handling etc.
The samples are in the return line and if laser counts
are used it may be that entrained air is coming out as
there is no pressure to keep them in 'solution' check
this by comparing the laser count with a microscope patch
sample.
Finally if there has been any VA analysis determine if
there has been deterioration in any of those results and
compare with the location of the sample counts to see
if there is a correlation.
