Predictive maintenance attempts to detect the onset of a degradation mechanism with the goal of correcting that degradation prior to significant deterioration in the component or equipment.Hence it is neccesary to study the reports of the machine and come up with an analisisy relevent to the life span of diffrent components
Basic hand tools and ,meter
Used Digital Tester and used Osciloscope if necessary.
The best tools for predictive maintenance are the people who have been working on the machines for many years
RCFA
FMEA
Walk By Inspections daily, weekly and monthly reports
Pareto Anlaysis
The best tools for predictive maintenance are the people who have been working on the machines for many years. A good maintenance manager will use these operators/technicians to update the computerised maintenance management system. Without information your CMMS means nothing.
Best Tool is "To maintain a good and detailed history Book"
1: Check the history / logbook of The equipment/Instrument, it will give you an idea about the frequency of problem and longest/shortest time span of problem free operation.
2: For every Failure, check the trends of all relevant process parameters for the past hour/span of time. You will find some predictiive clues, so in future you may set critical alarms on those vlaues of parameters.
3: For the control valves, even if they are controlling the parameters perfectly, always check the real opening vs given input, it will give you health of its calibration. so you can act before it leads to failure.
4: Review and adjust Periodic Maintenance accordingly.
used management tools PDCA or 5S pareto analyse
Thermal image of your equipment to identify any hotspots.
Vibration analyzer or using monitors built into the machinery you can monitor the vibrations of a machine.
Oil Analysis is conducted to check the condition of the oil itself and see what other particles and liquids are present
