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

Approach Advantages Disadvantages

Breakdown Maintenance

- Only repair when machine broken

down.

- Popular in undeveloped areas.

- Maybe short-term

reducing cost.

- 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.

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.

- 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

+ When the sharp rotating, there are two forces appeared: Friction Force and

Rotation Force.

+ These forces will be transmitted from Bearing to Machine Housing.

3.2. Four Popular Problems

There are four popular errors that Vibration

Technology can detect:

Imbalance

Misalignment

Looseness

Faulty Bearing

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

3.3. IFM Vibration Monitoring System – Efector Octavis

System Specification

Alarm Signals of Efecto Octavis System

- 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

can be operated.

+ Main alarm: (Red LED) Machine need to be maintained.

Bearing Fault

(1) Vibration

Amplitude

(2) Vibration

Frequency

- Production errors.

- Operating in bad-

lubricated

conditions.

- Small objects get

into bearing.

Especially, Efecto Octavis system still has ability to realize the current warning level

of the machine based on intelligent analysis ability.

- Data storage ability:

+ 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

logging time frame.

+ Direct warning to PLC.

+ System monitoring via PC, can be accessed via Internet.
