Obtaining Lubricating Oil Sampling
Obtaining a representative Lubricating Oil Sample is one of the most important parts of a scheduled Oil Analysis Program. If a sample does not represent the true condition of the lubricant and component at the time of sampling , the reliability of both the test result and its interpretation is affected.
Effective predictive and preventative maintenance programs rely on scheduled oil sampling and analysis programs to provide an accurate indication of equipment and lubricant condition. Monitoring, control and management of the operating condition of lubricating oils in equipment such as marine diesel engines, generators, turbines and gearboxes is an essential part of the day to day maintenance routines employed by Plant and Facilities Managers around the world.
When completing oil analysis forms and sample container labels, the following information should be noted:
UNIT ID NUMBER - A unique reference number for an entire functional unit. Examples include an aircraft registration number, company asset or inventory identification or a vehicle serial number.
COMPONENT - The type of system, such as engine or gearbox , from which the sample is taken. Other designations such as ‘left’, ‘number 3’, ‘rear’ or an actual description of the component’s use, such as ‘fan-drive’, are also needed for clear identification. This data may be obtained directly from an equipment or component service meter, or from general operating records.
TIME SINCE NEW OR LAST OVERHAUL - The operating hours or miles since the sampled compartment was first put into service, or since the last overhaul was performed. Since normal wear rates change over the lifetime of a component and break-in may resemble abnormal wear, this information is needed for interpretation.
TIME SINCE OIL CHANGE - The number of hours or miles of component use between the time the oil was changed and the time the sample was taken.
OIL TYPE - The manufacturer, product name, and SAE or ISO viscosity grade for the oil that was sampled. Since there is often more than one blend of the same viscosity product, the complete name is very important in determining which testing reference oil should be used.
OIL CONSUMPTION or MAKEUP OIL - The amount of oil added to maintain correct oil fill level. Complete oil changes should not be reported as makeup oil or identified as ‘new oil’
