We continue to delve into the benefits of oil mist lubrication in improving the reliability of mechanical seals.
Here Heinz Bloch explains that the root cause of mechanical seal failure is sometimes misdiagnosed. When a failure is verified in a centrifugal pump and it is inspected and the mechanical seal is found to be damaged, it is determined that the root cause has been the mechanical seal; when sometimes, the true root cause has been poor lubrication in bearings, which manifested itself with a break in the mechanical seal, as this element is a kind of fuse.
It is enough to observe the recommendation of API 751 that deals with Safe Operation in Alkylation Plants; where it is recommended to use oil mist lubrication to reduce the risks of having mechanical seal failures, which cause dangerous emissions to the environment.
We can then conclude with these last two posts, that the application of oil mist lubrication will achieve a benefit in terms of reducing failures originally attributed to mechanical seals.
