Preventive maintenance
Introduction
In maintenance operations,[1] preventive maintenance[2] is intended for the conservation of equipment or facilities by carrying out inspection and cleaning that guarantee their proper functioning and reliability. Preventive maintenance is performed on equipment that is in working condition, as opposed to corrective maintenance that repairs or brings into working condition equipment that has stopped working or is damaged.
The main objective of maintenance is to avoid or mitigate the consequences of equipment failures, preventing incidents before they occur. Preventive maintenance tasks may include actions such as replacing worn parts, changing oils and lubricants, etc. Preventive maintenance must prevent equipment failures before they occur.
Some of the common methods to determine which preventive maintenance processes should be carried out are manufacturers' recommendations, current legislation, expert recommendations and actions carried out on similar assets.
Norms and standards
ISO 14224 establishes guidelines for the collection and sharing of reliability and maintenance data on equipment used in the petroleum, petrochemical and natural gas industries. This framework allows structuring information on failures and preventive actions, improving planning and decision-making in maintenance programs.[3].
What is preventive maintenance for?
Preventive maintenance constitutes an action, or series of necessary actions, to extend the useful life of the equipment and facilities and prevent the suspension of work activities due to unforeseen events. Its purpose is to plan periods of work stoppage at specific times, to inspect and carry out maintenance actions on the equipment, thereby reducing corrective maintenance (emergencies).
And finally, in conclusion, this must be for the repair of machines and also so that they know how to damage machine tools and electrified machines very quickly.
