In the current highly competitive global economy we live in, there is always a drive to get the competitive edge. One way is to develop a maintenance strategy that will improve safety, meet production goals, increase uptime, increase plant efficiency and thus increase plant profitability.
There are four basic maintenance strategies:
This month, let’s take a look at the pros and cons of breakdown maintenance also known as run to failure, reactive or hysterical.
For many years (and still today in many plants) the philosophy has been to simply run the machine until it failed, deal with it via repair or replacement. Little thought was given to improving equipment reliability. The maintenance department was considered a huge cost sink, budgeted for and nearly impossible to budget accurately.
The following picture shows a bearing failure in centrifugal pump.
As you can see, there is much more damage than to the bearing alone. Also, the indirect cost of these failures are most often much higher than the direct costs.
So when or why would one choose breakdown maintenance as a strategy?
