Preventive maintenance is the regular and systematic inspection, testing, cleaning, and adjustment of equipment and systems to prevent or detect and correct faults before they cause breakdowns.
Preventive maintenance is typically performed on a scheduled basis, regardless of whether the equipment is showing any signs of wear or failure. This helps to ensure that problems are caught early and addressed before they cause major damage or downtime.
The goals of preventive maintenance are to:
-
-
Extend the lifespan of equipment and systems
-
Improve reliability and uptime
-
Reduce operating costs
-
Improve safety
-
Prevent unplanned downtime
-
Advantages: Preventive maintenance has many advantages, including:
-
-
It can help to prevent costly breakdowns and repairs.
-
It can improve the efficiency and performance of equipment.
-
It can help to extend the lifespan of equipment.
-
It can improve safety by identifying and correcting potential hazards.
-
It can help to reduce operating costs.
-
There are many different types of preventive maintenance, including:
-
-
Time-based maintenance: This type of maintenance is performed at regular intervals, regardless of the condition of the equipment.
-
Condition-based maintenance: This type of maintenance is performed based on the condition of the equipment, such as vibration levels or oil conditions.
-
Predictive maintenance: This type of maintenance uses data analysis to predict when maintenance is needed.
-
Implementation: The implementation of preventive maintenance can be complex and challenging. It requires a clear understanding of the equipment and systems involved, as well as the resources and budget available. It is also important to have a well-trained and experienced maintenance team in place.
Here are some examples of preventive maintenance:
-
Inspecting electrical wiring
-
Cleaning and adjusting air filters
-
