Explanation:

Understanding Types of Maintenance

In engineering and equipment management, maintenance is crucial for ensuring reliability and performance. The questions you've encountered focus on various maintenance strategies essential in keeping machinery operational and minimizing downtime.

  1. Preventive Maintenance: This type includes scheduled activities aimed at preventing breakdowns before they occur. For example, regular oil changes in machinery are part of preventive maintenance.
  2. Predictive Maintenance: This is based on monitoring the actual condition of the equipment to predict when maintenance should be performed. Condition monitoring is a key component of predictive maintenance.
  3. Corrective Maintenance: Also known as breakdown maintenance, this is performed after a failure occurs. An example would be repairing a machine after it has stopped functioning due to a fault.
  4. Scheduled Maintenance: Maintenance activities that are performed at predetermined intervals, such as monthly or annually, to keep the equipment in order.

Now, let's analyze the questions:

  1. The answer is A. Preventive maintenance, as it involves periodic inspections.
  2. The answer is D. Predictive, since condition monitoring supports it.
  3. The answer is A. Timely maintenance, which is not recognized as a formal type.
  4. The answer is D. Special maintenance, as this is typically less frequent than others.
  5. The answer is C. Breakdown maintenance, which is not scheduled.
  6. The answer is D. Installation of components, as it is not part of regular maintenance activities.
  7. The answer is B. Maintenance schedule needs to be decided based on maintenance requirements in the manual, describing routine preventive maintenance.
  8. The answer is B. Preventive, as it eliminates breakdown and outages.
  9. The answer is D. Preventive maintenance, which is most effective.
  10. The answer is B. Unscheduled maintenance, as casual maintenance is not planned.
  11. The answer is B. Timely maintenance, which refers to maintenance done when conditions require it.

In conclusion, understanding these types of maintenance helps ensure efficient operation and longevity of machinery by reducing unexpected breakdowns and improving the overall management of assets.
