Long term disuse of
diesel generator set can lead to shutdown, mainly due to complex chemical and physical changes between internal components of the unit and engine oil, cooling water, diesel, etc., resulting in decreased equipment performance and poor cooling effect.
Specific reasons and impacts
1. Decreased filtering capacity of the filter: The filter of the diesel generator set will experience a decrease in filtering capacity due to oil stains and impurities depositing on the filter screen wall. In severe cases, the oil circuit may be blocked, and the unit may go into shock due to insufficient oil supply.
2. Poor water circulation in the cooling system: If the water pump, water tank, and water pipeline are not cleaned for a long time, it will cause blockage and corrosion, resulting in a decrease in cooling effect, which may cause the unit to overheat and shut down.
3. Decreased equipment performance: Long term lack of maintenance can lead to wear and aging of internal components, affecting the generator's power generation capacity and stability, and making it prone to malfunctions and shutdowns.
4. Energy waste: Unbalanced, worn, or blocked internal components can lead to low heat transfer efficiency, inability to fully utilize energy, and result in resource waste.
5. Safety hazards: Internal oil leakage, leakage, or damage to components of the equipment may cause serious safety hazards such as fire or explosion.
6. Shortened equipment lifespan: Long term lack of maintenance can accelerate equipment wear and aging, shortening its service life.
7. Economic losses: Equipment damage and downtime can cause delays in production or project progress, increasing maintenance and replacement costs.
Maintenance suggestions
1. Regularly replace the filter: The commonly used unit needs to replace the three filters every 500 hours, while the backup unit needs to replace the three filters every two years.
2. Cleaning the cooling system: Regularly clean the water pump, water tank, and water pipeline to ensure smooth water circulation.
3. Check the battery: Keep the battery fully charged to prevent electrolyte evaporation and battery drop.
4. Change engine oil: When not in use for a long time, all used lubricating oil should be drained and new engine oil should be added.
5. Add antifreeze: Antifreeze should be added to the radiator to prevent the engine from rusting or freezing.
By implementing the above maintenance measures, the service life of diesel generator sets can be effectively extended, ensuring their normal operation when needed.
