Compare any groups of data that are trending toward unacceptable levels and make justifications based on these trends. 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.
In such cases, a second sample would ensure the data received is representative of the oil conditions and not simply a human error in sampling or analysis. Other tests that are based on the originating equipment include analytical ferrography, ferrous density, demulsibility and base number testing. Whilst spectrometric oil analysis is obviously very useful, there are two limitations: The size of particle that is picked up by the spectrometer is limited to a maximum of 8 to 10 microns (micrometres). From which internal component is the wear likely originating. The FTIR instrument recognizes each of these characteristics by monitoring the shift in infrared absorbance at specific or a range of wavenumbers.

Wear particle analysis determines the mechanical condition of machine components that are lubricated Oil Analysis: Sample Survey Results Improvement Done by MHA Soliman - Oil Analysis 28 29.
Compare any groups of data that are trending toward unacceptable levels and make justifications based on these trends. 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.
In such cases, a second sample would ensure the data received is representative of the oil conditions and not simply a human error in sampling or analysis. Other tests that are based on the originating equipment include analytical ferrography, ferrous density, demulsibility and base number testing. Whilst spectrometric oil analysis is obviously very useful, there are two limitations: The size of particle that is picked up by the spectrometer is limited to a maximum of 8 to 10 microns (micrometres). From which internal component is the wear likely originating. The FTIR instrument recognizes each of these characteristics by monitoring the shift in infrared absorbance at specific or a range of wavenumbers. High levels of AN usually indicate nitration, oxidation and contamination. and inquire about their expertise with these types of equipment. This spectrum is …

A plastic waste mixture (PWM) and waste lube oil (WLO) were mixed with mixing ratios of 33, 50, and 67 (w/w) % on a PWM weight basis, and thermogravimetric (TG) … FTIR is a quick and sophisticated method for determining several oil parameters including contamination from fuel, water, glycol and soot; oil degradation products … This CIMAC Recommendation describes the oil analysis process and gives information about each analysed parameter. There are three main categories of oil analysis… (Ref. Predictive maintenance is a strategy which increases the reliability of machines, allowing their true status to be identified as well as that of the lubricant which is in use. There is another rule which is commonly applied: when the ascending value of the AN and descending value of the BN cross. It answers questions such as: By detecting the presence of destructive contaminants and narrowing down their probable sources (internal or external), oil analysis can help answer questions such as: This form of oil analysis is about determining the presence and identification of particles produced as a result of mechanical wear, corrosion or other machine surface degradation.

//]]> If more testing is needed to answer advanced questions, these would be considered “exception” tests. The lubricant information can provide a baseline for several parameters, such as the expected viscosity grade, active additives and acid/base number levels. eval(mod_pagespeed_TnrAu1TW1S); Si continua navegando por este sitio web, acepta el uso de nuestras cookies. //]]> The “additional tests” section shows two final tests: acid number (AN) and particle size distribution (aka, particle count).
These are all required items that you should keep in your internal kit.
{{ data.caption }} When analyzing the acid number, you should have both a reference value and the ability to trend from past analysis. [CDATA[
A plot of absorbance, transmittance, or concentration versus wave-number is generated during the analysis of an oil sample, called the infrared spectrum. In the example above, the rise in silicon and aluminum could indicate dust/dirt contamination as the root cause. …

With all the variables to consider, it would be virtually impossible to identify a single lab as being the best. While most industrial lubricants classify viscosity in terms of ISO standardized viscosity grades (ISO 3448), this does not imply that all lubricants with an ISO VG 320, for example, are exactly 320 centistokes (cSt). Predictive maintenance is a strategy which increases the reliability of machines, allowing their true status to be identified as well as that of the lubricant which is in use. Table 2 shows oil analysis parameters and the technologies used to measure them Table 1 is a comparison of oil analysis parameters for engines and rotating machines. Having a baseline of new lubricant reference data is critical in assessing which additives are expected and at what levels. Standard alarm limits will be set by the oil analysis laboratory. The two most common types of atomic emission spectroscopy are rotating disc electrode (RDE) and inductively coupled plasma (ICP). This type of oil analysis focuses on identifying the oil’s current physical and chemical state as well as on defining its remaining useful life (RUL). Acid number and base number tests are similar but are used to interpret different lubricant and contaminant-related questions. Remember, there is always an explanation for each exceeded limit, and the root cause should be investigated. ... Three parameters …
Knowing which piece of equipment the oil was sampled from affects the ability to identify potential sources of the measured parameters, especially wear particles.

Friction, lubrication oil, wear, and wear particles are interactive and cannot be separated. Reviewing UOA Data Used oil analyses (UOAs) are tools. In addition to the raw data shown throughout the oil analysis report, graphs can help illustrate notable trends in the data. Generally, the lab performing the analysis will offer this kit with their service. This test reports results in parts per million (ppm), although data is often shown in percentages. It can find water in all three forms: dissolved, emulsified and free. Check other analyzed data such as FTIR oxidation levels, flash point, demulsibility, analytical ferrography, etc. Possible reasons for a moisture reading being too high or too low would include water ingression from open hatches or breathers, internal condensation during temperature swings or seal leaks. var wpv_pagination_local={"front_ajaxurl":"https:\/\/lubrication-management.com\/wp-admin\/admin-ajax.php","ajax_pagination_url":"https:\/\/lubrication-management.com\/wpv-ajax-pagination\/","calendar_image":"https:\/\/lubrication-management.com\/wp-content\/plugins\/wp-views\/embedded\/res\/img\/calendar.gif","calendar_text":"Select date","datepicker_min_date":null,"datepicker_max_date":null}; más información Aceptar. Monitoring the oil’s viscosity is critical because any changes can lead to a host of other problems, such as oxidation, glycol ingression or thermal stressors. Parallel Automatic Lubrication Systems. Too high or too low viscosity readings may be due to the presence of an incorrect lubricant, mechanical shearing of the oil and/or the viscosity index improver, oil oxidation, antifreeze contamination, or an influence from fuel, refrigerant or solvent contamination.

With elemental data related to contaminants and wear metals, alarms are set for upward trends in the data. Elemental analysis works on the principles of atomic emission spectroscopy (AES), which is sometimes called wear metal analysis. Every year, industrial plants pay millions of dollars for commercial laboratories to perform analysis on used and new oil samples.
