Connecting Reliability with Maintenance
The
increase numbers of physical assets in the recent years have made the maintenance
system of these assets quite difficult. An unreliable maintenance will cost the
company quite a big deal. The cost will include both the direct and indirect
costs associated with all reliability issues. Therefore to avoid these extra
costs, the maintenance systems of these assets have to be reliable.
Maintenance Reliability is the process to make sure that assets continue to
give the service what their users want them to do in the present operating
context. This RCM requires the machinery stakeholder to monitor, asses,
predict, and understand the working of the machine. Reliability Centered Maintenance provides a framework where the function and possible
failures of a machine can be analysed. Maintenance system is then established
not only to reduce maintenance cost, but increase the reliability of the assets
in its lifetime.
Reliability
Centered Maintenance is usually used to create a cost effective maintenance strategy to find out the causes of the machine failure. But there can be other
less tangible benefits which RCM may provide.
· Identifying hidden failure in the
machinery
·
Discovering significant and previously
unknown failure.
·
Producing training to system engineers
and machine operator.
·
Providing a detailed review and
improvement where necessary, for plant documentation.
The
use of this RCM will increase the efficiency of the machine thus giving more
output in the cost effective way.

Can You Believe That Machines Talk?
If there is any era that will always be
cherished by the world, it is the industrial revolution era. The era of
industrial revolution was one of the most innovative periods in the history of mankind;
it marked the introduction of robotics and machines in order to improve
production; developments that changed the course of human history.
Since those inspiring days machine and
heavy equipment have continued to dictate the daily lives of man. More and more
goods are being produced at a faster rate than ever before, individuals and
organisations have therefore developed more confidence in the ability of
machines and equipment to get the job done, faster, with more efficiency and
less supervision.
Most organisations now have a distinct
budget for purchase and maintenance of machines/equipments which can often run
into millions. Company executives, technicians and stakeholders are therefore
more aware of the need to have a comprehensive method of ensuring that
equipments perform to the highest expectation at the minimum cost, which is
where monitoring instruments as a concept came in to being.
Monitoring has become a crucial element
that has been built into machines in order to enhance the efficiency of the machine,
as well as the performance of the humans that work with them. The standard
maintenance procedure was the method that was initially used to monitor machines
performance and ensure that they produce at optimum capacity; however this
solution was at the mercy of human error and omissions in terms of both
assessment and actually doing the routine maintenance schedule.
The major difference from the standard
maintenance procedure and the new world monitoring is that while the old method
only aims to correct or repair faults, and prevent break down by randomly
changing equipment parts, condition monitoring aims to thoroughly check every equipment part and component for
performance; as well as provide analytical information on the gradual
degradation and overall performance of the machine. In fact, it simply listens
to everything the machine is saying and provides solutions in real time.
This type of maintenance process is carried
out through a variety of techniques, which include oil analysis, vibration
analysis, thermal imaging and ultrasonic measurement. Most of these methods
offer a diagnostic, speedy and accurate information flow that will ensure that
equipment are maintained and monitored with a reliable level of precision.
Here is a little more on different
condition monitoring techniques:
Oil analysis, as the name suggests,
involves carrying out detailed analysis of the contaminant and condition of the
oil in the machine. It is one of the most commonly used methods that helps
determine the exact component of a machine that is degrading.
Vibration analysis provides information on
the parts of the machine that needs to be properly fixed or secured. This
method pinpoints parts of the machine that are out of place or misaligned.
Thermal imaging is designed to pick up heat
signals that will notify extremely hot components. Ultrasound measurement is
used to measure pipe thickness and other equipment that has only one accessible
point.
