Planned Preventive Maintenance

Introduction to Planned Preventive Maintenance (PPM)

What is PPM?

Planned preventative maintenance is a form of scheduled or planned maintenance that is carried out on a piece of equipment or machinery on a regular basis.

Planned preventative maintenance is used to reduce machine downtime, keep the performance of the machine level high and prevent issues from occurring. PPMs are incorporated into machine service plans to prevent high levels of reactive maintenance, instead, a good PPM program can turn reactive work into a predictive and proactive strategy.

OR

Planned Preventative Maintenance (PPM) is a proactive maintenance strategy where equipment, systems, and assets are serviced at scheduled intervals to prevent unexpected failures.

The goal is to keep everything in optimal working condition, minimize downtime, and extend the lifespan of critical assets. This method is widely used across industries to ensure efficiency and reliability.

Planned Preventive Maintenance

Planned Preventive Maintenance (PPM) is a proactive approach to maintenance that involves regularly scheduled inspections, tests, and repairs to equipment, facilities, and systems in order to prevent breakdowns and minimize the risk of equipment failure.

The goal of PPM is to extend the lifespan of equipment and facilities, improve their performance and reliability, and reduce the risk of downtime and unplanned repairs.

TYPES OF PPM

Planned Preventive Maintenance (PPM) is categorized into different types based on scheduling, execution, and purpose. Below are the main types:

1. Time-Based Maintenance (TBM) : Maintenance performed at scheduled intervals (daily, weekly, monthly, or annually) regardless of equipment condition.

• ✔ Example: Changing air filters in computers every three months.

✔ Use Case: Suitable for components with predictable wear and tear.

2. Condition-Based Maintenance (CBM) : Maintenance is performed when equipment shows signs of wear or potential failure.

✔ Example: Cleaning dust buildup from a computer’s cooling fan when temperatures start rising.

✔ Use Case: Used for critical systems where early warning signs indicate maintenance needs.

Planned Preventive Maintenance

3. Predictive Maintenance (PdM) : Uses data and monitoring tools (e.g., sensors, AI, machine learning) to predict failures before they happen.

✔ Example: Monitoring server temperature and scheduling fan replacements before overheating occurs.

✔ Use Case: Applied in high-tech environments where system downtime must be minimized.

4. Risk-Based Maintenance (RBM) : Prioritizes maintenance based on risk assessment, focusing on high-risk equipment first.

✔ Example: Regularly inspecting UPS systems in hospitals to prevent sudden power failures.

✔ Use Case: Useful in healthcare, aviation, and industrial sectors where failures can have severe consequences.

Planned Preventive Maintenance

5. Corrective Preventive Maintenance: A combination of preventive and corrective maintenance, addressing minor issues before they escalate.

• ✔ Example: Replacing a hard drive that shows bad sectors before it completely fails.

✔ Use Case: Ideal for IT systems and industrial machinery 6. Prescriptive Maintenance (RxM) : Uses advanced analytics and AI to suggest the best maintenance actions.

✔ Example: An AI-powered system analyzing historical data and recommending when to replace server components.

✔ Use Case: Applied in smart hospitals, IoT-driven industries, and cloud computing environments.

NOTE: By implementing the right type of PPM, organizations can enhance efficiency, reduce costs, and extend equipment lifespan

PPM procedures to protect the computer from environmental damage

To protect a computer from environmental damage using Planned Preventive Maintenance (PPM) procedures, follow these steps:

1. Protection from Dust

✔ Regular Cleaning: Use compressed air or a soft brush to remove dust from vents, fans, and internal components.

✔ Air Filters: Install dust filters on air vents and clean them periodically.

✔ Proper Placement: Keep the computer in an elevated position, away from dusty floors or carpets.

✔ Enclosed Cabinets: Use dust-proof enclosures in high-dust environments.

2. Protection from Extreme Temperatures

✔ Proper Ventilation: Ensure adequate airflow around the computer to prevent overheating.

✔ Cooling Systems: Use cooling fans, heat sinks, or liquid cooling systems for better heat dissipation.

✔ Temperature Control: Keep the room temperature between 10°C and 30°C for optimal performance.

✔ Avoid Direct Sunlight: Place the computer away from direct sunlight or heat source

3. Protection from Moisture

✔ Dehumidifiers: Use a dehumidifier to control moisture levels in humid environments.

✔ Silica Gel Packs: Place silica gel packets inside the computer case to absorb excess moisture.
