lube oil analysis parameters

At this point it is necessary to top-off or change the oil. Acid number testing is performed on non-crankcase oils, while base number testing is for over-based crankcase oils. Standard alarm limits will be set by the oil analysis laboratory. What is Oil Analysis Oil analysis is the sampling and laboratory analysis of a lubricant's properties, suspended contaminants, and wear debris.

//Em que consiste a contagem de partículas? The i-pH value is the measurement of the acid components dissociated with the potential of corrosiveness with metals. Findings – Physical and chemical properties related to degradation of the lube oil are considered as lubricating oil performance parameters. SynLube™ Lube‑4‑Life ® " 100% Synthetic Super Lubricants, since 1969 " Spectroscopy Analysis INTRODUCTION. If the rate of BN depletion is too great and the oil … [Article] [CDATA[
Turbine lube-oil systems are designed to cool bearings, flush contaminants away from rotating parts, prevent leakage of gases, provide hydrostatic lift for shafts and actuating valves in the hydraulic circuit and protect lube …
  • To better understand your lab’s capabilities, open an honest dialogue with them and ask about their core competencies. Verify elemental wear data and compare to reference and trended data. Be upfront about the type of testing you would like performed. There is another rule which is commonly applied: when the ascending value of the AN and descending value of the BN cross.
    • Several methods are used to measure viscosity, which is reported in terms of kinematic or absolute viscosity. for Used Oil Analysis. Along with the trend data, graphs should show typical averages, warning (marginal) limits and alarm (critical) limits.

    The “physical tests” section of a report offers details on viscosity at both 40 degrees C and 100 degrees C, along with the viscosity index and percentage of water. This test reports results in parts per million (ppm), although data is often shown in percentages. The last section of the oil analysis report generally provides written results for each of the final few test samples along with recommendations for required actions.

    As the oil remains in service, this BN additive is depleted.
    The spectrometer … If so, why? Compare written results and recommendations with known information on the oil and machine, such as recent changes in environmental or operational conditions or recent oil changes/filtration. and inquire about their expertise with these types of equipment.
  • The geographic location of an oil analysis lab is tertiary to the quality of the data and the turnaround time for the results. These limits should be modified depending on the type of data collected, the type of lubricant and the machine’s known operating conditions.
