Marine diesel generator serve as power supply devices on ships, and due to frequent exposure to the humid marine environment, they require moisture protection. Without proper protection, the corrosive effects of seawater and atmospheric moisture can severely damage the electrical components and mechanical parts of the marine diesel generator.
Primary defense starts with proper housing installation. Marine diesel generator should be housed in well-ventilated compartments with vapor barriers and dehumidification systems. Desiccant breathers installed on ventilation openings prevent moist air from entering the marine diesel generator casing while allowing necessary airflow. Regular inspection of these breathers ensures continuous protection.
Electrical components within marine diesel generator demand special attention. Moisture-resistant coatings on control panels, waterproof connectors, and silicone sealants on junction boxes form essential barriers. Many modern marine diesel generator incorporate heated windings that automatically activate when humidity reaches critical levels, preventing condensation buildup.
Operational practices significantly impact moisture control. Marine diesel generator should be run regularly even during port stays, as operation generates heat that drives out accumulated moisture. After shutdown, proper cooling procedures prevent condensation formation inside the marine diesel generator.
Maintenance routines must include thorough drying of all exposed surfaces and immediate repair of any paint damage to the marine diesel generator's exterior. Storage of spare parts in vacuum-sealed packages with desiccants preserves their integrity until needed.
By implementing these comprehensive measures, operators can ensure marine diesel generator maintain optimal performance throughout their service life in challenging maritime conditions.
