Procedural Steps in Preventive Maintenance

In fact, there is no readymade or on the shelf preventive maintenance programme for any organisation. It is tailored to fit the requirements of the plant. Probably this is due to the plants differ in size, age, location, manpower, resource, layout and machinery. However, the preventive maintenance is carried out in the following steps, which will appear more or less same in any industry.

Procedural Steps in Preventive Maintenance

• The PM is done on the machines those on which we require more available time of operation. Hence, such machines are first identified. Most common practice is that the identification of such machines is done by both production department and PEM.
• To carry out PM, the parameters will be identified by PEM. Based on these parameters, a checklist is prepared for each and every machine.
• The next step of PM is to determine the interval of the checking or inspection of the machine condition. This interval is fixed on the basis of past records of the frequency of failures.
• The parameters of the check list the machine is inspected and overhauled or made minor repairs or dismantled partially or totally based on the machine condition.

Though the basic concept is derived from Preventive Maintenance only, due to their difference in the structure or dominant factors of the system the PM has taken some improvised shapes/advancement like the scheduled maintenance, shutdown maintenance, planned maintenance, productive maintenance, maintenance prevention, etc..
