Understanding and Managing Oil Leaks " We all know leaks make a mess. Why do they keep happening? How do we know if a leak is something to be concerned about or if it is just commonplace for plant equipment? Well, given that rotating equipment and lubricated equip- ment are practically synonymous, oil leaks can be more common than we would like. us, understanding the risks associated with an oil leak is important. W hile preventing leaks all together is desirable, it's often not achievable. erefore, we must be ready to reduce the leaks to an allowable amount based on vari- ables of risk. For now, we'll focus on oil leaks, although much of what will be mentioned could also apply to grease leaks. Any time oil escapes the lubri- cation system (sump, piping, etc.) and enters the external surround- Bennett Fitch | Noria Corporation ENERGY CONSERVATION, HEALTH & ENVIRONMENT Factor: E3M ings, this is an external leak. We are often aware of this, as there is visual evidence of the oil dripping out onto other components and forming a puddle on the f loor. However, another type of leak occurs when unwanted oil seeps between internal chambers inside a lubrication system. is is called an internal leak. Not many consider internal leaks at all, much less the risks associated with them. is is largely because of the lack of evidence. Unless we are moni- toring pressure gauges or operational movements closely, these internal leaks may go unnoticed. But regardless of the type of leak, what is considered normal? Is there any amount of leakage that is allow- able? When should a leak be taken seriously and corrected? Is this a maintenance activity that is largely reactive or can steps to be taken to be more proactive? Leaks are something I often inspect for and help identify through Noria's Lubrication Program Devel- opment (LPD).
