Want this as a site license? Scope 1. This guide is intended to aid the equipment manufacturer, installer, and turbine operator in coordinating their efforts to obtain and maintain clean lubrication and control systems. These systems may be on land or marine turbine generators and propulsion and mechanical drive equipment.

A number in parentheses indicates the year of last reapproval. Achieving this requires use of proper purification methods toensure that the oil is free of detrimental contaminants. In addition, it requires an ongoing monitoringprogram to ensure that the oil quality is within specifications and that corrective action is taken tominimize contaminant generation and ingression.
The benefits of purification of an operatinglubrication system can be significantly reduced if the lubricating systems are not initially cleaned toa level that will prevent component damage on initial start up after manufacturing or rebuilding.
Care and thorough cleaning are required to minimize and remove contaminants during fabrication,rebuilding, or installation, or combination thereof. Because contaminants will remain from theseprocesses, it is necessary to flush and purify the system to remove them prior to startup.
Ongoingpurification is required to maintain pure oil during operation. In new systems, the emphasis is on theremoval of contaminants introduced during manufacture, storage, field fabrication, and installation. Inoperational systems, the emphasis is on the removal of contaminants that are generated or carried induring operation, and by malfunctions that occur during operation or contaminants that are introducedduring overhaul, or both. This guide is intended to aid the equipmentmanufacturer, installer, and turbine operator in coordinatingtheir efforts to obtain and maintain clean lubrication andcontrol systems.
These systems may be on land or marineturbine generators and propulsion and mechanical drive equip-ment. For systems using nonpetroleum based fluids, thisguide may not be appropriate. For nonpetroleum products,consult the equipment and fluid manufacturers. Some equipment specified herein, however,may not be appropriate for all systems. Moreover, in situationswhere specific guidelines and procedures are provided by theequipment manufacturer, such procedures should take prece-dence over the recommendations of this guide.
It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.
Referenced Documents2. Current edition approved May 1, Published July Originally approvedin Last previous edition approved in as D — DOI: The solid can be a fiber, a finepowder, or porous particles. Contaminants such as water andparticulate are generally more dense than the oil and migrate tothe outside of the centrifuge because of centrifugal force.
Cleaning can include removal of contaminant byshoveling, sweeping, squeegee, vacuuming, wiping, displacingwith clean, dry compressed air and can be done with the aid ofcleaning solutions.
Cleaning solutionsmay be classified as chemical cleaners, solvent cleaners, or oilsoluble cleaners. A coalescer generally consists of a coalescingcartridge s and a hydrophobic barrier that hinders water frompassing out with the oil. It may also contain a filter locatedupstream or downstream, or both, of the coalescing car-tridge s. Oxidation reaction will be accelerated by thepresence of oxidation accelerators such as metallic contami-nants and water.
Significance and Use4. No phase of these proce-dures should be undertaken without a thorough understandingof the possible effects of improper system preparation. Theinstallation, cleaning, and flushing of the equipment should notbe entrusted to persons lacking in experience. Review of thisguide can provide guidelines for discussion with prospectivecontractors. Contamination Control Overview5. The main focus of this guide is on theminimization, monitoring, and control of contaminants: waterand both soluble and insoluble stationary and suspended contaminants.
A more detailed discussion of these types ofcontaminants is given in Appendix X1. This includes proper construction and maintenancepractices, appropriate purification equipment, and regularmonitoring of contaminants. The contamination control pro-gram must be capable of identifying and measuring contami-nants and controlling them at, or preferably below, componenttolerances.
In particular, the sensitivity of bearings, gears,seals, and proportional and servo valves should be reviewed. As described in X2. These and recommendations of the fluid manu-facturer must be considered when employing contaminationcontrol systems.
In addition, there are insoluble contaminants oxidation precursors that are below machine tolerances, butas their volume amasses they create a potential for sludge andvarnish creation as a normal consequence of oxidation reac-tions.
Contamination monitor-ing is discussed in Appendix X2 and contamination controlmethods in Appendix X3. Inclusion of filtration in steam andgas turbine lubrication systems is discussed in Practices Dand D respectively. Heating is discussed inAppendix X4. Properlydesigned systems can normally control water and insolublecontaminants in operational systems. If, however, it is neces-sary to remove soluble contaminants other than water, an oilchange and also possibly a flush may be required.
