What are condition monitoring techniques?
Condition monitoring to help prevent machine failure Condition monitoring is the process of monitoring machinery – by vibration, temperature or other methods – to identify a significant change which could indicate a developing fault. It is a major component of predictive maintenance.
What are the various methods and devices for condition monitoring?
The following list includes the main condition monitoring techniques applied in the industrial and transportation sectors:
- Condition monitoring overview.
- Vibration analysis and diagnostics.
- Lubricant analysis.
- Acoustic emission.
- Infrared thermography.
- Ultrasound.
- Oil condition sensors.
What are the means of monitoring pump performance?
Another method of pump monitoring is to measure the temperature rise of the liquid through the pump. Pump efficiency can be calculated from the measured data of inlet temperature, the differential temperature and the head. If the efficiency changes over time, comparisons can be made on plots of efficiency versus head.
What is condition monitoring in aviation?
As such, ACMSs allows you to monitor and control the status of the onboard systems and equipment, as well as variations to the flight conditions and to the operation of the equipment. …
What is the purpose of condition monitoring?
Condition monitoring is an efficient, non-intrusive process with the potential to save thousands of pounds in secondary damage, lost production and unnecessary maintenance. Making it part of your routine maintenance is critical as it allows you to get to know the equipment better and allows for long-term productivity.
Why vibration is preferred as most common tool for condition monitoring?
Vibration screening is one of the most effective ways to detect and prevent equipment failure or downtime. It can screen most faults including imbalance, misalignment, looseness and late-stage bearing wear, providing precipitous warning of impending failure.
What is offline condition monitoring?
Offline Condition Monitoring is a term used for less critical or semi-critical assets where periodic scanning is required, and continuous scanning is not required. In Offline Condition Monitoring, regular scanning of assets is good enough to practice.
What is condition based monitoring maintenance?
Condition-based maintenance (CBM) is a maintenance strategy that monitors the actual condition of an asset to decide what maintenance needs to be done. CBM dictates that maintenance should only be performed when certain indicators show signs of decreasing performance or upcoming failure.
What is condition based service?
In newer BMW automobiles, a Condition Based Service (CBS) system is used. This system creates individualized service requirements based on data collected from the vehicle using sensors, driving conditions and time intervals. It details what items need to be replaced or serviced.
What are examples of predictive maintenance?
Some examples of using predictive maintenance and predictive maintenance sensors include vibration analysis, oil analysis, thermal imaging, and equipment observation.
What is predictive maintenance strategy?
Predictive maintenance is a proactive maintenance strategy that uses condition monitoring tools to detect various deterioration signs, anomalies, and equipment performance issues. The goal of predictive maintenance is to optimize the usage of your maintenance resources.
What is difference between preventive and predictive maintenance?
The key differences between preventive vs. predictive maintenance are: Preventive maintenance occurs on the same schedule every cycle — whether or not the upkeep is actually needed. With predictive maintenance, repairs happen during machine operation and address an actual problem.
How do you start predictive maintenance?
To recap, the steps to starting a predictive maintenance program at your facility are:
- Start small.
- Identify PdM ready assets.
- Identify resources required.
- Implement asset monitoring and begin data collection.
- Create algorithms to predict failures.
- Apply to pilot asset.
What are predictive maintenance tools?
There are six primary PdM tools available:
- Vibration analysis.
- Ultrasonic analysis.
- Infrared analysis.
- Oil analysis.
- Laser-shaft alignment.
- Motor circuit analysis.
What is RCM methodology?
Reliability centred maintenance (RCM) is a corporate-level maintenance strategy that is implemented to optimize the maintenance program of a company or facility. The final result of an RCM program is the implementation of a specific maintenance strategy on each of the assets of the facility.
What is an element of predictive maintenance?
Some of the main components that are necessary for implementing predictive maintenance are data collection and preprocessing, early fault detection, fault detection, time to failure prediction, maintenance scheduling and resource optimization.
What is predictive maintenance Why is it important?
Predictive Maintenance drives you to the future by catching shortcomings in any early-stage or the symptoms that may subsequently cause more defects. It helps industries with decision-making and real-time monitoring. It furthermore helps regulate the machine’s life, physical conditions, and work efficiency.
Why do we need predictive maintenance?
Predictive maintenance allows manufacturers to lower maintenance costs, extend equipment life, reduce downtime and improve production quality by addressing problems before they cause equipment failures. More high-quality data we can feed into the predictive model the better its accuracy.
What are the benefits of predictive maintenance?
Benefits of Predictive Maintenance include:
- Reduction or near elimination of unscheduled equipment downtime caused by equipment or system failure;
- Increased labor utilization;
- Increased production capacity;
- Reduced maintenance costs;
- Increased equipment lifespan.
What is routine maintenance?
Routine maintenance refers to any maintenance task that is done on a planned and ongoing basis to identify and prevent problems before they result in equipment failure. Some common routine maintenance includes regular inspections or service work.
What is time based maintenance?
Definition. Time-based maintenance (TBM) is maintenance performed on equipment based on a calendar schedule. This means that time is the maintenance trigger for this type of maintenance. This means that it can be used with both predictive maintenance and preventative maintenance.
What is planning and scheduling in maintenance?
In the maintenance world, planning and scheduling are two different functions that work together to create a maintenance program. Planning is the the process of planning, while scheduling is the process of reconfiguring workloads in a production/manufacturing process.
What is difference between scheduling and planning?
The difference between planning and scheduling is that planning addresses what will be done and how it will happen, while scheduling addresses who will do it and when.
What are the principles of scheduling?
Let’s take a deeper look at each of the six maintenance scheduling principles.
- Plan for the lowest required skill level.
- Prioritize daily and weekly schedules.
- Schedule based on the forecasted hours available for the highest skill level.
- Assign work for every work hour available.
What are the benefits of planning and scheduling?
Planning and scheduling streamlines communication, helps control costs and helps avoid scheduling conflicts.
