Maintenance & its types

2. What is maintenance
 The process of preserving a condition or
situation or the state of being
preserved .
 ‫یا‬ ‫رکھنے‬ ‫برقرار‬ ‫کو‬ ‫حال‬ ‫صورت‬ ‫یا‬ ‫حالت‬ ‫ایک‬
‫عمل‬ ‫کا‬ ‫حالت‬ ‫کی‬ ‫ہونے‬ ‫محفوظ‬

3.  Maintaining, repairing, and replacing if
necessary devices, equipment,
machinery, building infrastructure, and
supporting utilities in industrial,
business, governmental, and residential
installations

4. Types of Maintenance

5. Breakdown maintenance
 It means that people waits until
equipment fails and repair it. Such a
thing could be used when the equipment
failure does not significantly affect the
operation or production or generate any
significant loss other than repair cost.

6. Preventive Maintenance
 IT IS A DAILY MAINTENANCE
(CLEANING, INSPECTION, OILING
AND RE-TIGHTENING), DESIGN TO
RETAIN THE HEALTHY CONDITION
OF EQUIPMENT AND PREVENT
FAILURE THROUGH THE
PREVENTION OF DETE.

7. Predictive Maintenance
 This is a method in which the service life of
important part is predicted based on
inspection or diagnosis, in order to use the
parts to the limit of their service life.
Compared to periodic maintenance,
predictive maintenance is condition based
maintenance. It manages trend values, by
measuring and analyzing data about
deterioration and employs a surveillance
system, designed to monitor conditions
through an on-line system.

8. Corrective
 It improves equipment and its
components so that preventive
maintenance can be carried out reliably.
Equipment with design weakness must
be redesigned to improve reliability or
improving maintainability.

9.  Periodic maintenance:
Maintenance carried our according to
predetermined schedule. It may be
quarterly, halfyearly etc.

10. Other Considerations
 When designing the Maintenance Plan should be
taken into account two important considerations
affecting some equipment in particular. Firstly, some
equipment are subjected to legal rules that regulate
their maintenance, forcing them to perform certain
activities with an established frequency.
Secondly, some of the maintenance activities can not
be performed with the regular maintenance
equipment (either their own or hired) because it
requires knowledge and / or specific resources that
are only up to the manufacturer, distributor or a
specialist team.

11.  Some equipment are subjected to rules or regulations by the
Administration. Above all, there are equipment that are
hazardous to people or the environment. The Administration
requires the completion of a series of tasks, tests and
inspections, and some of them must be performed by
companies duly authorized to carry them out. These tasks must
necessarily be incorporated into the Maintenance Plan of the
equipment, whatever model you decide to apply.
 Some of the equipment subjected to this type of maintenance
are:
 Equipment and devices under pressure
 Installation of High and Medium Voltage
 Cooling Towers
 Certain lifts: service or people
 Vehicles
 Fire Prevention Facilities
 Storage tanks of certain chemicals

12. Benefits of Maintenance
 Prolonged life of company equipment
 Less unplanned downtime caused by
equipment failure
 Less unnecessary maintenance and
inspections
 Fewer errors in day-to-day operations
 Improved reliability of equipment
 Fewer expensive repairs caused by
unexpected equipment failure that must be
fixed quickly
 Reduced risk of injury

13. Maintenance work planning

14. 5 things to consider as a
Supervisor
 People
 Place
 Time
 Tools Equipments etc.
 Information

15. People
 When we talk about people we talk
about people. Do I need a welder,
mechanic, electrician, fabricator etc.
 No. of persons.

16. Place
 Nature of place.
 Must have information about that place

17. Time
 When we carried out maintenance (day,
month etc.)
 How much time it will take.
 During shutdown or regular production
activities

18. Tools & Equipments
 Inventory
 Do I need lifter, crane etc.

19. Information
 Information about the system

20. 10 biggest causes
of machinery
breakdowns

21.  Not reading the operator's manual

22.  Improper
maintenance

23.  Poor electrical connections

24.  Overrunning machine's capability

25.  Not replacing worn parts when
needed

26.  Tightener misalignment

27.  Improper storage

28.  Improper weather-related use

29.  Ignoring warning signals

30.  Asking untrained personnel to
operate equipment

31. How Can Preventive Maintenance
Software Help?
 Many companies choose preventive maintenance
software to coordinate all their preventive
maintenance tasks because it simplifies what is
otherwise a complex process. Preventive
maintenance software stores a company’s
maintenance data on a computer (or in the cloud) to
easily keep track of all inspections, repairs and
replacements. With all data conveniently stored in
one place, preventive maintenance software can be
used to effectively manage work orders, purchase
orders, inventory and maintenance records.
Preventive maintenance software even prioritizes
maintenance tasks and gathers information a
technician needs to perform maintenance work
