method and device for assessing the condition of a liquid in a liquid lubrication system for a work system operable in at least two different modes of operation

摘要

A method and apparatus for assessing the condition of a liquid in a liquid lubrication system for a working system operable in at least two different modes of operation, said method comprising measuring monitored liquid condition data (401), determining a mode of operation. operation (310) of said work system and, based on said current mode of operation (310), select a corresponding mathematical model, model corresponding simulated liquid condition data (320) based on said mathematical model, evaluate the comparing the monitored liquid condition data (401) with said simulated liquid condition data (320), thereby providing a significantly normal distributed data set (402) for said condition evaluation of the liquid, and device for applying said method.
