MAINTENANCE

1. PREVENTIVE

   • Programmed procedure that prevents the occurrence of failures.
   • MAIN ACTIVITIES
     • Cleaning
     • Inspection and review
     • Adjustment or calibration
     • •Change of parts
     • Lubrication
   • It has
     • DISADVANTAGES
       • Requires experience of the maintenance staff as from the recommendations of the manufacturer to make the maintenance program to the equipment.
       • It does not allow the exact determination of wear or depreciation of equipment parts.
     • ADVANTAGES
       • Significant risk reduction due to failure or leakage.
       • Low cost
       • Reduces the probability of unforeseen stoppages.
   • CHARACTERISTICS
     • It is done periodically and routinely.
     • Tasks and budgets are planned.
     • Inspect equipment or items to detect faults in their early stages, and correct them before it is too late.
   • Highly recommended in production lines and in continuous processes
   • FREQUENCY
     • It is necessary to measure the operating time, since most of the components of the equipment are damaged by use.

2. CORRECTIVE

   • Set of technical tasks, aimed at correcting equipment failures that demonstrate the need for repair or replacement.
     • Is classified in:
       • CONTINGENT
         • Must be applied immediately
         • Corrects faults presented in equipment or machinery during the production process
         • Resources applied:
           • Human
           • Technical
           • Economic
       • PROGRAMMED
         • Your repair is not urgent, you can schedule the repair
         • You have some time to make the necessary repairs
         • It is programmed annually with the help of:
           • Manuals
           • Logs
           • Software
           • Technical specifications of spare parts
   • CHARACTERISTICS
     • Consists of intervening the equipment after the failure is present
     • Breakdowns are dealt with as they arise
   • It has
     • ADVANTAGES
       • Quick repair
       • Lower short-term costs
       • Minimum planning required
     • DISADVANTAGES
       • Unpredictable
       • Slow operations
       • Long-term costs may be higher
   • FMEA Failure Mode, Effects Analysis
     • Method used to prevent failures and to analyze the risks of a process to identify causes and effects in order to determine the actions that will be used to inhibit failures.
       • Steps:
         • 1. List all possible failure modes
         • 2. Set your priority index
         • 3. Find solutions for most important failure modes
   • PROCEDURE FOR PERFORMING
     • Consists of using formats or a maintenance software, such as:
       • • Corrective work order
       • • Report of off-duty equipment
       • • Request for corrective service
       • • Report of failures
