摘要:
A diagnostic system for a work machine includes a data storage device (210) in which sensor information (A) input from a sensor (101A) that senses an oil property of oil used for operation of the work machine and an abnormality degree determination value defined for each kind of the sensor information (A) are stored, and an arithmetic processing device (104) that executes first processing of discriminating the degree of abnormality level of the oil based on the sensor information (A) and the abnormality degree determination value, second processing of determining whether or not necessity to carry out oil analysis involving oil extraction exists based on the degree of abnormality level of the oil discriminated in the first processing, and third processing of outputting information indicating that the oil analysis is necessary to other terminal if it is determined that the oil analysis is necessary in the second processing.

For checking engine oil, especially containing rate of FAME, we provide a measuring device including a cylindrical and upright analysis vessel having a reading scale with which a surface boundary is measured. In the vessel, the engine oil is mixed with reagents including alcohol(s) and a demulsifier. And the decreased volume is checked as volume of the FAME contained in the engine oil.
摘要:
Die Erfindung betrifft ein Prüfverfahren und eine Prüfvorrichtung zum Ermitteln einer Ölseparationsneigung von Schmierfetten unter einer Druckbelastung. Bei dem Verfahren wird ein mit Schmierfett (27) gefülltes Probevolumen (2) über einen vorbestimmten Prüfzeitraum (32) mit einem vorbestimmten Prüfdruck beaufschlagt, das Schmierfett (27) des Probevolumens (2) mit einem Ölabsorptions- oder Ölausscheideorgan (11) in Kontakt gebracht und die Änderung des Probevolumens (2) aufgrund einer Absorption oder Ausscheidung von aus dem Schmierfett (27) separiertem Öl (29) durch das Ölabsorptions- oder Ölausscheideorgan (11) am Ende des Prüfzeitraums (32) ermittelt. Um die Ölseparationsneigung eines Schmierfettes genauer abschätzen zu können, wird bei dem erfindungsgemäßen Verfahren der zeitliche Verlauf der für die Ölseparation repräsentativen Änderung des Probevolumens (2) über den Prüfzeitraums (32) erfasst.
摘要:
The invention relates to a method for analyzing a lubricating oil. The method utilizes 2-dimensional gas chromatography (2D GC) to determine the amounts of paraffins and isoparaffins in the oil. The compositional information thus obtained is used to calculate a paraffin index correlated with formulated oil MRV.
摘要:
An apparatus (10) for analyzing lubricant oils and functional fluids includes an optical emission spectrometer (OES) (26) having a substantially continuously valued wavelength versus intensity output (140). The OES (26) analyzes light captured from a spark emission stand (58) through which the fluid sample is flowed. An expert system (160-172) operates according to a set of Rules, and generates diagnostic text (174) for an operator based on the information about the fluid sample provided by the OES (26) and other measurement devices. The apparatus (10) is reduced in size, weight and cost.
摘要:
The invention relates to a method for analyzing a lubricating oil for low temperature properties. The method utilizes 2-dimensional gas chromatography (2D GC) to determine the amounts of paraffins and isoparaffins in the oil. In particular, the method analyzes for a particular isoparaffin fraction which is correlated to low temperature performance. The compositional information thus obtained is correlated with formulated oil Mini Rotary Viscometer (MRV) properties.
