4 types reactive- response to equipment malfunction preventive- periodic checks predictive- periodic measurements and trending of equipment process prevention- equipment design is based on minimal maintenance requirements
An important part of the process in managing inventories is to maintain items through periodic replenishments preventive maintenance and capital improvements.
The preventive maintenance of steam turbine mainly entails frequent servicing of the parts. This will ensure a smooth performance of the steam turbine.
The answer is time and money. Preventive maintenance reduces downtime and cost associates with hardware failures and software obsolescence. Preventive maintenance helps provide high level of availability of system function and obtains great return on investments of hardwares and softwares.
Preventive Maintenance is the meaning of PM.
Changing the oil in your car
documenting the details and frequency of each maintenance task.
explanation
A preventive maintenance plan tends to evolve from a history or pattern of malfunction within an organization.
Caring for a computer is called maintenance or preventive maintenance.
There is no comparison, but there is a connection.First of all, there is no such thing as Total Preventive Maintenance. There is a well consolidated Plant Maintenance discipline called Preventive Maintenance.There are other names for this discipline, for instance: SCHEDULED MAINTENANCE -- PERIODIC MAINTENANCE -- PLANNED MAINTENANCE -- ROUTINE MAINTENANCE.Even if there are slight differences in their meaning, they can be considered as alternative names for Preventive Maintenance.There are also many definitions of Preventive Maintenance. Most probably the best and simplest definition is:"Periodic and systematic inspections and detections of plant/machinery, targeting at identifying deterioration - panned restoration of detected deterioration"On the other hand, Total Productive Maintenance (TPM) is not only a Plant Maintenance discipline, it's now recognised also as a Plant Management philosophy.Invented and developed by S. Nakajima well over 20 years ago, TPM targets at achieving the highest Equipment Effectiveness(value added to production by equipment) with the highest Efficiency (optimal equipment conditions throughout its life-cycle at the lowest total cost).To the purpose, TPM deploys a number of operational Disciplines and Techniques, including:Preventive MaintenanceAutonomous MaintenanceMaintainability ImprovementMaintenance PreventionP-M AnalysisPoka-Yokeand many others.Modern TPM may be also beneficially associated and used in conjunction with other technical Maintenance disciplines such as RCM (Reliability Centred maintenance), IPF (Instruments Protective Function), RBI (Risk Based Inspections), etc.TPM however is considered a very modern Lean discipline and part of the Lean philosophy because of its strong approach to maximising output value while cutting drastically all equipment-related losses and all equipment-related waste.In conclusion, TPM is a Plant Management discipline and philosophy. Preventive Maintenance is one possible Plant Maintenance discipline. Total Preventive Maintenance does not exist.Carlo Scodanibbio - Industrial Consultant
