What is condition monitoring system?
Condition monitoring (CM) is a maintenance approach that predicts machine health and safety through the combination of machine sensor data that measures vibration and other parameters (in real-time) with state-of-the-art machine monitoring software.
What are the types of condition monitoring?
Vibration analysis condition monitoring techniques include shock pulse analysis (e.g. for rotating equipment), fast fourier analysis, broadband vibration analysis (e.g. to detect bearing wear), ultrasonic analysis (e.g. to detect leaks), power spectral density, time waveform analysis (e.g. for machines with X-Y probes) …
Which are the basic steps in condition monitoring?
STEP 1: Set-up of equipment register. STEP 2: Assessment of machinery status and their criticality for the facility operation. STEP 3: Identification of appropriate machine condition monitoring technique for each of the available assets. STEP 4: Selection of available technologies on the market.
What are the main components of a condition monitoring system?
Component Condition Monitoring
- Compressors.
- Steam Turbines.
- Thrust Bearings.
- Preventive Maintenance.
- Predictive Maintenance.
- Rotating Equipment.
- Shutdown.
Why is condition monitoring used?
The use of condition monitoring allows maintenance to be scheduled, or other actions to be taken to prevent consequential damages and avoid its consequences. Condition monitoring has a unique benefit in that conditions that would shorten normal lifespan can be addressed before they develop into a major failure.
Why is condition monitoring important?
Condition monitoring allows for faster repairs and, by analyzing variables, helps ensure better reliability and maintenance. For example, knowing if a machine is malfunctioning, the system may be restored with fewer visits and lower costs.
What are the key features of condition monitoring?
Listed in here we have the most relevant ones:
- Vibration analysis.
- Temperature monitoring.
- Current measurement and analysis.
- Speed Measurement.
- Thermography.
- Ultrasound.
- Lubricant analysis.
- Acoustic analysis.
What are the benefits of condition monitoring?
Advantages of Condition Based Monitoring
- Increased uptime/reduced downtime.
- Reduction in/elimination of unplanned failures.
- Decreased maintenance costs.
- Increased asset life.
- Reduction in collateral asset damages.
- Greater ease in prioritization and planning of work orders.
What are the disadvantages of condition monitoring?
Disadvantages
- Condition monitoring test equipment is expensive to install, and databases cost money to analyze.
- Cost to train staff–you need a knowledgeable professional to analyze the data and perform the work.
- Fatigue or uniform wear failures are not easily detected with CBM measurements.
