Plant maintenance

2. PLANT MAINTENANCE
 Plant maintenance is an
important service function of a
production system.
 Maintenance means care,
upkeep.
 It helps in increasing the
operational efficiency of Plant
facilities.
 Maintenance is the
procedure of finding the faults in
any equipment/machine and also
removal of faults.
 It may be before the
breakdown or after the
breakdown.

3. PLANT MAINTENANCE
 Plant maintenance is defined
as a set of activities that are necessary to
keep machinery, parts and types of
equipment in good operating conditions
to avoid production stoppage and loss.
 Plant maintenance usually to
the methods, strategies and practices
used to keep an industrial factory
running efficiently.
 The general aim of Plant
maintenance is to create a productive
working environment that is also safe for
workers.

7. Preventive Maintenance
 It is based upon the principle that ‘preventive is
better than cure’ .
 It is a set of activities that are performed on plant
equipment, machinery, and systems before the
occurrence of a failure in order to protect them and
to prevent or eliminate any degradation in their
operating conditions.
 It has three types
1. Running maintenance
2. Scheduled maintenance
3. Shut down maintenance

8. Corrective Maintenance
 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.
 It has 2 types
1. Breakdown maintenance
2. Shutdown maintenance

9. Thermal Plant Maintenance

10. ADVANTAGES OF PLANT
MAINTENANCE
 Greater safety to workers.
 Reduction in production down time.
 Less spare parts.
 Prolongs the life of the machine.
 Maintenance quality and continuity of
production.

11. DISADVANTAGES OF PLANT
MAINTENANCE :
 High control on records and analysis, planning and scheduling.
 Monitoring of parameters like temperature, lubricature, noise,
corrosion, leaks etc are High. The equipments to do that also
are costly.
 Optimum PM is required,
hence correct judgment
is needed. Too much or
too little is not good.
