What is maintenance?
Maintenance, otherwise known as technical maintenance, refers to a set of processes and practices which aim to ensure the continuous and efficient operation of machinery, equipment, and other types of assets typically used in business.
Planned
Maintenance:
Planned maintenance refers
to any maintenance activity that is planned, documented, and scheduled. The aim
of planned maintenance is to reduce downtime by having
all necessary resources on hand, such as labour and parts, and a strategy to
use these resources.
Unplanned
/Unscheduled Maintenance:
Unplanned maintenance is
any maintenance task that occurs unexpectedly. It happens when there is no
formal strategy in place to address a repair, replacement, or inspection before
it’s needed. Unplanned maintenance is commonly the result of equipment failure
that was not anticipated.
TYPES OF PLANNED MAINTENANCES
Routine/ Preventive Maintenance
(BEFORE A
FAILURE HAS OCCURRED)
This type of maintenance is implemented on a fixed schedule and typically includes activities such as inspecting, cleaning, washing, replacing, and checking. It is typically performed in the downtime between shifts or on weekends to avoid affecting productivity goals. Routine maintenance has two objectives; to identify existing issues so they can be corrected ASAP(as soon as possible) and to prevent possible issues from becoming a reality through consistent care.
Corrective Maintenance
(AFTER A FAILURE
HAS OCCURRED)
If during your routine
maintenance inspection of a car you discover signs of severe wear-and-tear, you
need to perform corrective maintenance. When computer or gauge readings for a
machine show unusual, possibly hazardous anomalies, you need to perform
corrective maintenance. Corrective maintenance pertains to the repairs and
replacements necessary to get an asset back up and running at full power and
optimal condition.
Predictive Maintenance
This maintenance type
focuses on techniques used to determine the appropriate schedule for planned
and corrective maintenance. Its primary goal is to predict, through a variety
of testing methods, when a machine will start experiencing severe wear and tear
so corrective maintenance can be scheduled without affecting productivity goals
and before the machine breaks down.
Emergency/ Breakdown Maintenance
It is the maintenance
required when an asset or piece of equipment suffers an unexpected breakdown or
change in condition that results in an immediate threat to health and
safety.Emergencies almost always happen without warning, so emergency
maintenance cannot be scheduled, but every maintenance program should include
plans for dealing with emergencies when they do occur.
DIFFERENCE BETWEEN TYPES OF MAINTENANCE
Preventive
vs Predictive
Both preventive maintenance and predictive maintenance are designed to increase the reliability of assets and reduce the amount of reactivity to failures. The main difference between the two is that preventive maintenance is scheduled at regular intervals while predictive maintenance is scheduled as needed based on asset conditions.
Preventive
vs Breakdown
Preventive maintenance and breakdown maintenance both seek to maintain and repair equipment but they have very different ways of doing this. In some ways, breakdown maintenance is the opposite of preventive maintenance because maintenance work doesn’t occur until a downtime event happens as opposed to avoiding downtime events by performing maintenance before they happen.
