1- Preventive maintenance: Equipment is maintained before any fault occur or the equipment to be in working condition. It's to maintain a level of certain service on equipment, programming or configuration if required and done by maitenance department.

2- Periodic Maintenance: The basic maintenance of equipment by its user or operator. It consists of data collection, visual inspection, cleaning, lubrication, re tightening of screws for which only a brief training is required and.

3- Corrective maintenance: It is to correct the defect to be found in the equipment and are corrected by the maintenance department.

Indeed there are more than main three types as the following: 1- corrective maintenance. 2- preventive maintenance(scheduled). 3-perdective maintenance. 4-reliability centered maintenance RCM. 5- proactive maintenance.

  • Preventive Maintenance: It is to maintain a level of certain service on equipment,to remove intermediate fault. Its protect equipment from sudden breakdown.  
  • Predictive Maintenance: It pursues for report the status and operational capacity of the installations by knowing the values of certain variables, which represent such state and operational ability. To apply this maintenance, it is necessary to identify physical variables (temperature, vibration, power consumption, etc.). Which variation is indicative of problems that may be appearing on the equipment. This maintenance it is the most technical, since it requires advanced technical resources, and at times of strong mathematical, physical and / or technical knowledge.
  • Corrective maintenance: When any equipment is in break down, then only maintenance / repairing is required instantly. The set of tasks is defind to correct the defects  in the equipment

At the top level, I see maintenance being either preventive or corrective:

  • When we do preventive maintenance we are doing a task before a failure has occurred. That task can be aimed at preventing a failure, minimising the consequence of the failure or assessing the risk of the failure occurring.
  • When we are conducting corrective maintenance the failure has now occurred and we are basically reinstating equipment functionality. To be clear, corrective maintenance can be the result of a deliberate run-to-failure strategy.

Within within the category of preventive maintenance there are several types of maintenance:

  • Time Based Maintenance (TBM)
  • Failure Finding Maintenance (FFM)
  • Risk Based Maintenance (RBM)
  • Condition Based Maintenance (CBM)
  • Predictive Maintenance (PDM)

When it comes to corrective maintenance there are two types:

  • Emergency Maintenance
  • Deferred Maintenance

More detail on these different types of maintenance, when to use them, how to use them can be found in this article: 9 Types of Maintenance | ROAD to RELIABILITY™

There are 4 types of maintenance activities:

 

1. Corrective Maintenance: Maintenance is carried out following a detection of an anomaly and aimed at restoring normal operating conditions. This strategy may be cost - effective until catastrophic faults occur.

 

2. Preventive Maintenance: This is carried out at predetermined intervals or according to a prescribed criteria, aimed at reducing the failure risk or performance degradation of the equipment. Maintenance cycles are planned according to the need to take the device out of service.

 

3. Risk-based maintenance: This is carried out by integrating analysis, measurement and periodic test activities to the standard preventive maintenance. All equipment displaying abnormal values is refurbished or replaced.

 

4. Condition based Maintenance: Real actual equipment condition is continuously assessed by the on-line detection of significant working device parameters and their automatic comparison with average values and performance. Maintenance is carried out when certain indicators give the signaling that the equipment is deteriorating.

  • Corrective maintenance: The set of tasks is destined to correct the defects to be found in the different equipment and that are communicated to the maintenance department by users of the same equipment.
  • Preventive Maintenance: Its mission is to maintain a level of certain service on equipment, programming the interventions of their vulnerabilities in the most opportune time. It is used to be a systematic character, that is, the equipment is inspected even if it has not given any symptoms of having a problem.
  • Predictive Maintenance: It pursues constantly know and report the status and operational capacity of the installations by knowing the values of certain variables, which represent such state and operational ability. To apply this maintenance, it is necessary to identify physical variables (temperature, vibration, power consumption, etc.). Which variation is indicative of problems that may be appearing on the equipment. This maintenance it is the most technical, since it requires advanced technical resources, and at times of strong mathematical, physical and / or technical knowledge.
