Is the most expensive maintenance type in terms of total costs in the long term.
Reactive is the most costly.
Reactive maintenance is the most costly maintenance strategy, and you can expect to spend up to 10x more than on a pro-active strategy.
Which maintenance strategy does oil analysis fall into?
Oil Analysis is proactive, but can also be considered predictive too.
Oil analysis is not usually considered reactive as the idea is to catch failures before they happen. However, ferrographic analysis post-failure can be done to identify why a failure occured.
Oil analysis is not preventative as although it is designed to reduce or prevent unplanned downtime, preventative maintenance in this context means changing parts and components early, e.g. changing your oil twice as much to prevent failures. In contrast oil analysis can actually help you keep your oil in use for longer as it is condition based.
Oil analysis is both predictive in terms of its ability to identify wear rate changes so it can predict a failure, but it is also proactive as it can highlight problems that may cause wear in the future such as contamination, and encourage the maintenance operator to address these proactively
Preventative maintenance can also be called...
Preventative is changing before a failure will statistically occur
Preventative is scheduled at particular times in a machines life such as an annual service or when the machine has performed a certain number of hours, miles or kilometers. It is based on statistical analysis of a population of machines to determine when they are likely to fail, and repair or replacement is scheduled prior to this.
Options that would produce a correct answer flag: time-based,calendar,time based,scheduled,repair before failure, replace before failure
Oil analysis can detect causes of wear before wear occurs. What is the most likely cause it will detect?
Oil analysis is proactive since it can detect the causes of wear such as contamination.
Contaminants such as dirt, water, fuel, soot and coolant can all be detected by oil analysis before wear occurs, making it a very powerful tool to use with your machinery.
Answers that would have given a correct response include: dirt,water,H2O,contaminants,contaminant,contamination,Si,Silicon,Silicon & Aluminium,soot,fuel,coolant,anti-freeze,antifreeze,glycol
What does NDT stand for?
Non-destructive Testing
Non-destructive testing is as opposed to testing to destructive testing such as in failure analysis or component load testing where the test may involve damaging the component to test endurance, strength etc.
Answers that would produce a correct answer include:Non-destructive Testing, non destructive testing, nondestructive testing
