Research by turbine manufacturers, power companies and oil suppliers has shown the main causes of the problems to be an increased use of API Group II base oils in turbine oils, combined with an increase in steam turbine peaking operation. The highest profile problems were entrained air and foam, decreased demulsibility and formation of varnish. voir moins
Vibration Analysis: The Other Half of the Equation STLE (Society of Tribologists & Lubrication Engineers) The premise behind vibration analysis is that specific mechanical defects produce characteristic vibrations at different frequencies. Vibration analysis is an excellent complement to oil analysis in some applications. The need for integrated monitoring de...voir plus The premise behind vibration analysis is that specific mechanical defects produce characteristic vibrations at different frequencies. Vibration analysis is an excellent complement to oil analysis in some applications. The need for integrated monitoring depends on the applicability of the procedures and the importance of the equipment. voir moins

What is the Significance of Acid Number and Base Number in Used Engine Oil Analysis? Which is More Important? STLE (Society of Tribologists & Lubrication Engineers) Acid number represents the free acids that can corrode parts. Base number represents the amount of original acid-neutralizing additive remaining and, hence, the expected life of the oil. While both are important, more TLT readers came down in favor of bas...voir plus Acid number represents the free acids that can corrode parts. Base number represents the amount of original acid-neutralizing additive remaining and, hence, the expected life of the oil. While both are important, more TLT readers came down in favor of base number or total base number as the more critical metric. voir moins
