1. Description
In the paper, the writer just want to provide very first basic knowledge about
Maintenance Strategies and one kind of Vibration Monitoring application from IFM for
every people, it definitely is not academic one. For further reference, please contact to:

1.1. Why we need the Maintenance?
 Minimize errors
o Balancing the machine components.
o Improving maintenance operation.
o Cleaning oil, lubricating mechanical parts.
 Prevent effects to production operation
o Avoiding unwanted reparation.
o Stopping chain defects to other parts.
o Saving maintenance cost.
1.2. Maintenance Approaches
Breakdown Maintenance
- Only repair when machine broken
down.
- Popular in undeveloped areas.
- Maybe short-term
reducing cost.
 HP: +84 983 886 943 || +84 906 701 599
- High cost for
replacing broken
parts (Normally
above ten-times in
compare to
maintenance cost).
- High downtime.
- Need large spare
parts quantity.
- Generate a lot of
safety problems

- Customer must purchase for
reparation when machine broken
down.
 HP: +84 983 886 943 || +84 906 701 599
during operation
and reparation.
Preventive Maintenance
- Maintain, repair before machine
broken down.
- Schedule maintenance plan based on
experiences.
- The most popular approach at the
current, this approach will be good
with the assumption that the machines
and parts will be broken as descripted
in the original datasheet.
- Need to answer two questions below:
(1) WHEN is the machine broken
down?
(2) WHY the machine will be
broken?
- Depending on
experiences, it takes
years to have a good
maintenance plans.
There’re several
problems at the
beginning of Plan
Process:
 Over-maintained.
 Over-lubricated.
 Over-stock
Spare parts.
Predictive Maintenance
- Not unpredicted
downtime.
- Not unpredicted
errors.
- Not associated
damages.
- Depending on
individual
experiences.

~ 4 ~
- Maintain, repair based on experienced
about machine condition.
- Predict when machine broken down.
- Maintain, repair at the most suitable
time.
- Only maintain, repair when machine
“require”.
- Assess risk intelligently.
- Monitor machine status online.
- Predict error modes.
- Every maintenance
plans will be pre-scheduled.
Proactive Maintenance
- “Repair one time, repair right place”
or “Precious Maintenance”.
- Inherited and developed from
Predictive Maintenance.
- Predict error modes by using
intelligent analysis tools.
- Change the machine design,
procurement, and maintenance to
reduce errors and increase
reliabilities.
- Precise balance…
- Proactive and
precise maintenance.
- Not unpredicted
errors.
- Not need to stop
machine to inspect
operating condition.
- Minimize
maintenance cost.

2. Proactive Maintenance’s Technologies
- Existent technology:
+ Vibration Analysis
+ Oil Analysis
+ Wear Particle Analysis
+ Thermography
+ Ultrasound
+ Steam trap
Proactive Maintenance Technology
3. Vibration Analysis
3.1. General Knowledge
- Vibration signal changed during operation
condition changed.
- Causes of Vibration
Rotation Force.
+ These forces will be transmitted from Bearing to Machine Housing.

There are four popular errors that Vibration
Technology can detect:
 Imbalance
 Misalignment
 Looseness
 Faulty Bearing
~ 6 ~
3.2. Four Popular Problems
Errors Causes Images
Imbalance
- The heavy points on
the shaft make the
machine imbalance
during rotating
process, the vibrated
shaft causes bearing
broken down.
Misalignment - Misalignment causes
machine vibrated
strongly and damage
bearing.
Looseness - Machine
components are not
connected tightly
during installation
- During operation,
components

Amplitude
(2) Vibration
Frequency
- Production errors.
- Operating in bad-lubricated
conditions.
- Small objects get
into bearing.
- The system monitor and analyze online machine operating conditions, which divide
into three warning levels:
+ Normal – OK: (Green LED) Machine in Normal Status
+ Pre-alarm: (Yellow LED) Machine begins to have problems; however, it still

3.3. IFM Vibration Monitoring System – Efector Octavis
System Specification
Alarm Signals of Efecto Octavis System
can be operated.
+ Main alarm: (Red LED) Machine need to be maintained.

Especially, Efecto Octavis system still has ability to realize the current warning level
+ Manage parallel up to 7 VE modules, or 24 VSE modules.
+ Real-time data, stored on VSE module up to at least 03 weeks depending on

of the machine based on intelligent analysis ability.
- Data storage ability:
logging time frame.
+ Direct warning to PLC.
+ System monitoring via PC, can be accessed via Internet.
