2. helps in maintaining and increasing the
operational efficiency of plant facilities.
Maintenance is the procedure of finding the
faults in any equipment/Machine and also
removal of fault.
It may be before the breakdown or after the
breakdown
general aim of plant maintenance is to create
a productive working environment that is also
safe for workers.

4. . Retention aspects of safety and comfort
Maintaining the function and performance of
buildings
Maintaining the image and appearance of
buildings
Preservation of the asset building

5. Planned maintainance
a)Preventive maintenance
b)Corrective maintenance
c)Predective maintenance
Unplanned maintainance

6.  It is a set of activities that are performed on plant
equipment, machinery, and systems before the
occurrence of a failure in order to prevent or
eliminate any degradation in their operating
conditions
 the maintenance carried out at predetermined
intervals or according to prescribed criteria
 intended to reduce the probability of failure or the
degradation of the functioning and the effects
limited.

7. Advantage of preventive
maintainance
Provides for extended life of the building and
grounds.
Maintains compliance with current codes and
standards
Achieves reductions in energy consumption.
Enhances the performance of assets by
increasing uptime

8. Three types of preventive
maintenance
Running maintenance
Scheduled maintenance
Shutdown maintenance

9. Running maintenance
Running maintenance which includes those
maintenance activities that are carried out
while the machine or equipment is running
Example – lubrication, adjustment of nuts and
screws, tightening of loose nut and bolts

10. Scheduled Maintenance
is any variety of scheduled maintenance to an
object or item of equipment.
is a scheduled service visit carried out by a
competent and suitable agent, to ensure that
an item of equipment is operating correctly

11. Shutdown maintenance
Which is a set of preventive maintenance
activities that are carried out when the
production line is in total stoppage situation.
These are performed generally after three or
six months.
These involves the inspection of plant items
which are known or suspected to occur.

12.  In this type, actions such as repair, replacement, or
restore will be carried out after the occurrence of a
failure in order to eliminate the source of this failure
or reduce the frequency of its occurrence.
 It also include the different types of actions like
typical adjustment of redesign equipment.

13. Types of corrective maintenance
Breakdown maintenance
Shutdown maintenance

14. Breakdown maintenance
It is an emergency based policy in which the
plant or equipment is operated until it fails
and then it is brought back into running
condition by repair.
The maintenance staff locate any mechanical,
electrical or any other fault to correct it
immediately.

15. It is feasible for the small factories where
a)There are few types of equipment.
b)Machine and equipments are simple and does
not require any specialist.
c)Where sudden failure does not cause any
serious financial loss.

16. Difference of preventive and
corective maintenance
Preventive Corrective
Done before problem Done after problem
Done frequently Done randomly
Will minimize the need of
corrective
Will maximize the preventive
action

17. it involves the prediction of the failure before
it occurs, identifying the root cause for those
failures symptoms and eliminating those
causes before they result in extensive damage
of the equipment
performed continuously or at intervals
according to the requirements to diagnose
and monitor a condition or system.

18. Maintenance action which is carried out
without any fore thoughts or prior planning is
called unplanned maintenance.
Emergency maintenance is one of the
example of unplanned maintenance.
