Types of Maintenance

1. Preventive Maintenance (PM): Proactive maintenance is key to avoiding unexpected downtime. Regular inspections, lubrication, and component replacements are scheduled to prevent equipment failures before they occur. Think of it as giving your turbine a regular check-up to keep it healthy and running smoothly.
2. Predictive Maintenance (PdM): With advancements in technology, predictive maintenance has become increasingly prevalent. Utilizing sensors, data analytics, and predictive algorithms, engineers can anticipate equipment failures based on real-time data. By identifying potential issues early, corrective action can be taken to prevent costly breakdowns.
3. Corrective Maintenance: Sometimes, despite our best efforts, failures occur. Corrective maintenance involves addressing issues as they arise, whether through repairs, replacements, or overhauls. While reactive in nature, swift action can minimize downtime and mitigate further damage.

Key Components to Monitor

1. Rotor Blades: These are the heart of the turbine, responsible for extracting energy from the steam. Regular inspection ensures they remain free from erosion, corrosion, and fatigue, which can compromise efficiency and performance.
2. Bearings: Proper lubrication and alignment are crucial for bearing health. Excessive vibration or overheating can indicate misalignment or inadequate lubrication, warranting immediate attention to prevent catastrophic failure.
3. Steam Path Components: Components such as nozzles, diaphragms, and labyrinth seals are subjected to high temperatures and pressures. Monitoring for wear, erosion, and steam leakage is essential to maintain efficiency and prevent steam losses.
