Contaminants created during the combustion procedure or
caused by wear and tear (both normal and excessive) should be removed from the
oil therefore debris may damage slipping surfaces, obstruct normal motion and
cause precision components to seize.
Contaminants of the nature tend to trigger a series
reaction as the resulting put on generates more particles, therefore increasing
the rate of deterioration. Even though removing them from the essential oil will
reduce this danger, it is equally important to determine the supply of the
contamination in order to reduce the possibility of a major breakdown.
A number of methods may be used to analyse lubricating
oil for impurities. Such as the detection of asphaltene contamination,
spectrometry, microscopy, compound counting and analytical ferrography. In
addition to determining whether or not the necessary oil is still suitable for
use, these types of tests also provide valuable info regarding the condition of
the motor.
Such checks are usually performed ad hoc rather than as
a part of the actual vessel’s planned maintenance program. When evaluating the
results, all possible influencing aspects should be considered including recent
powerplant maintenance and changes to functional conditions and routines. The
outcomes should also be scrutinised very carefully for tends, comparing the
particular figures with previous reviews.
