Diagnostic Maintenance

Machinery, equipment, buildings and other service facilities are subject to deterioration due to their use and exposure to environmental conditions. This deterioration, if undetected, culminates in rendering these facilities unserviceable and makes them standstill. Industries therefore have no other choice but to attend to them time to time, to repair, recondition and restore them so as to elongate their useful life to the maximum extent possible. In this context, the maintenance assumes importance as an engineering function and is made responsible for provision of the condition of these machines, equipment, buildings and services that will permit uninterrupted implementation of plans requiring their use. To achieve this various strategies/philosophies and policies have been developed particularly in recent past. These philosophies, their approaches and relevant techniques are explained in this block. This unit particularly deals with fault diagnosis, diagnostic maintenance, FMEA and FMECA.
