What can be a result of a dirty lube oil strainer?

A dirty lube oil strainer can lead to low bearing oil pressure because it restricts the flow of oil through the system. When the strainer is clogged or dirty, it impedes the normal circulation of lubricant, which in turn prevents adequate oil from reaching the bearings. This restriction can lead to insufficient lubrication, resulting in reduced pressure at the bearings and potentially causing friction and wear. Proper maintenance of the lube oil strainer is essential for ensuring consistent oil flow and maintaining adequate oil pressure to protect the machinery.

In contrast, high bearing oil pressure, increased lubrication efficiency, and improved oil flow would not occur with a dirty strainer. Instead, those situations require the strainer to be clean and functioning properly to allow optimal oil circulation.
