Using RCM Turbo
We have now looked at the
how to lay out the PM, the next thing to concentrate on is the �when�
should this PM be done? Most PM�s get initiated in a ritualistic manner.
Some form of active god has caused a problem, and we are now going to put
a PM in place to insure it never happens again. This now becomes tribal
lore and when asked 10 years later, �Why do we inspect that elevator
once a week though we never find anything wrong?� The response is always
the same, �Because.�
should only want to do the work that you need to do when you need to do
it. The most effective way to do this is by using RCM tools such as
FAILURE MODES AND EFFECTS ANALYSIS. The only problem with this is that it
can take you years and lots of time to complete just one PM. We found a
new tool that can streamline this process down to minutes. It can be
accomplished by anyone even an apprentice. This software is called RCM
Turbo and it takes you through the FMEA Process in a logical order quickly
and efficiently. It starts with doing a critical analysis of the process
unit (see Fig. 1).
Once you have
accomplished this and have looked at all the possible primary failures, it
allows you to go down to the maintainable equipment level (see Fig. 2).
By following a series of questions it will tell you
what type of PM should be carried out. This would include FTM or �fixed
time maintenance� CBM or �conditioned-based monitoring� or RTF
�run to failure� (see Fig. 3).
The last thing that RCM Turbo
allows you to do is a reliability risk assessment. It will actually chart
what you need in time and cost for 100% reliability but if 98% reliability
is good enough it will tell you what the new time frame will be. This
allows you to set your PM�s to the correct frequency and risk to be the
most effective for your facility quickly and easily (see Fig. 4).
The other aspect of this tool is it allows you to build a library of
associated equipment, so that you do not have to repeat the FMEA Process
on each one. We have found that by having the correct task sheets and the
right frequencies, PM�s become more efficient and people become more
attuned to the whole concept of Preventive Maintenance. When your PM�s
are run through RCM Turbo you will find you are now focusing on things
that you never thought of and that you have much more time to do
corrective maintenance work. Our studies have shown that most companies
tend to over PM when they do PM and to not PM the correct equipment. We
know that there is not a perfect PM but it is a working document that RCM
Turbo can quickly and efficiently help write.
