Objective 07: Monitoring Equipment Flashcards
Condition Monitoring
Measuring relevant indicators of equipment condition that can be useful in predicting deterioration and the likelihood of failure.
What is the purpose of Condition Monitoring?
To make decisions about the type of maintenance required.
What are the different Condition Monitoring Technique categories?
- Vibration Monitoring
- Oil Analysis
- Thermography
- Ultrasonic Inspection
- General Monitoring, including equipment and process performance, output, pressures, and temperatures.
Which Condition Monitoring Technique does not require specialized training?
General Monitoring
How is General Monitoring done?
- Manually by Paper log sheets
- Computerized monitoring program using portable hand-held collectors or by monitoring control systems with permanently mounted sensors
What should always be noted on log sheets?
- Date and time of entry
- Name of person
- Unit of measurement
- Alert values, where relevant
What sequence should parameters on a log sheet follow for recording purposes?
The order that the readings are taken (this may differ between operators)
What sequence should parameters on a log sheet follow for viewing purposes?
Logically according to systems and types of reading.
How can both priorities in sequencing parameters on a log sheet be accommodated?
Sequence for viewing purposes but have an extra column with the input sequence for reference.
Should calculated values for parameters be added to the log sheet?
If it is simple.
What should operators filling out log sheets be trained in?
- How to take readings
- What readings are used for
- What to do if an alert value is exceeded
What is the best practice with Alert Value readings?
Document them separately from the log sheet by someone familiar with the equipment and its operation.
What is the best way to monitor changes in equipment condition?
Display indicator values on a trend chart.
How do some CMMS’s aid Condition Monitoring?
They include a condition monitoring feature that can automatically trigger maintenance tasks, e.g. by having 3 different alert bands that indicate progression of importance from alert to alarm to danger.
