3.1 Predictive Maintenance

Predictive maintenance is based primarily on detecting a failure before it happens , to allow time to correct it without injury to the service, or stopping production , and so on. These controls can be carried out periodically or continuously , depending on the equipment , the production system , etc. .

This is done using diagnostic instruments , apparatus and nondestructive screening, which checks the standing of system components without stopping .

The tools used are often used continuously and in many cases are monitored from a central computer . An example would be temperature indicators of the equipment or the standing of hard disk utilization .

Predictive maintenance of a system to:

Reduces downtime.
Lets follow the evolution of a defect in time.
Enhance management of maintenance personnel .
Checking the condition of machinery , both on a regular basis as you accidentally lets make an archive of the mechanical behavior .
Know exactly the time limit for action that does not involve the development of a glitch .
Deciding on a line stop devices at critical moments.
Planning of internal forms of operation or purchase of new equipment
Allow performances history knowledge to be used for corrective maintenance.
