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.

Planned maintainance
a)Preventive maintenance
b)Corrective maintenance
c) Predective maintenance
Unplanned maintainance

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.

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

Three types of preventive maintenance
Running maintenance
Scheduled maintenance
Shutdown maintenance

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

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

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.
![Page 12: Maintenance work](https://reader034.vdocument.in/reader034/viewer/2022042817/55a6b3e81a28ab012c8b457e/html5/thumbnails/12.jpg)
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.

Types of corrective maintenance
Breakdown maintenance
Shutdown maintenance
![Page 14: Maintenance work](https://reader034.vdocument.in/reader034/viewer/2022042817/55a6b3e81a28ab012c8b457e/html5/thumbnails/14.jpg)
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.

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.

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

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.
