At Pure Oil, we analyse the filter cartridge once it has been used, as it contains the contaminants that have been removed from the system (and will therefore not show up in an oil sample). Microscopic images are taken of the filter and the images highlight any abnormalities, contaminants and debris. You can see for yourself what is circulating in the oil – you may be surprised what is traveling through your machinery.
Common Contaminants include:
- Solid Contamination: This shows that the machine/system is generating a large amount of wear and an investigation into the cause should be instigated (could be Metal, Plastic, Paint). Rubbing, laminar, fatigue and sliding wear can be distinguished using a finer focus, giving a greatly magnified image to work with.
- Light Contamination: Can show a need for better breathers, can point to a source of ingress and can help eliminate further introduction of foreign bodies into the system.
- Water Contamination: is able to be trapped within the filters and gives a caved in look when it has absorbed it. By observing the filter itself, we were able to inform the customer of the previous (possibly still current) water ingress which allowed them to search for the cause.
- The recommendation would be to have the machine/system checked for any type of ingress (water, dirt, atmospheric particles), to have the oil filtered to ensure all contaminants are removed and to ensure the machine/system is properly maintained.
- By highlighting the fact that the contamination exists, it provides the opportunity to improve and the knowledge to head in the right direction.
