When storing diesel generator for a short period of time (such as 1 to 3 months), the following precautions should be taken to ensure their performance and extend their service life:
1、 Diesel generator fuel treatment
Drain the fuel: Before storage, all the fuel in the tank should be drained to prevent deterioration or blockage of the fuel circuit due to prolonged standing.
Cleaning the fuel tank: If conditions permit, the fuel tank can be cleaned to remove residual oil and impurities, preparing for the next use.
2、 Cleaning and drying of diesel generators
Comprehensive cleaning: Use compressed air and a brush to clean the exterior and interior of the diesel generator (such as the radiator, intake duct, etc.), removing dust, oil, and debris.
Keep dry: After cleaning, place a desiccant inside the unit to absorb any residual moisture and prevent rusting.
Sealed air inlet: Use oil paper or specialized sealing materials to seal the air inlet of the diesel generator to prevent dust and moisture from entering.
3、 Maintenance of lubrication system for diesel generator
Drain the engine oil: Clean the oil filter and engine oil passage to prevent oil deterioration or sedimentation.
Cylinder lubrication: Inject an appropriate amount of oil into each cylinder from the exhaust manifold, and then rotate the crankshaft dozens of times to evenly distribute the oil inside the cylinder, protecting the cylinder walls and piston rings.
Lubricate the valve: Remove the valve cover and lubricate the valve structure with dehydrated engine oil to prevent rusting or sticking of the valve.
4、 Maintenance of diesel generator electrical system
Disconnect the battery: Disconnect the positive and negative terminals of the battery from the starter motor to prevent battery self discharge and loss of power.
Regular charging: During storage, the battery should be charged with an external charger at regular intervals (such as monthly) to maintain sufficient power.
5、 Storage environment and conditions for diesel generators
Indoor storage: Store the diesel generator in a dry, ventilated, non corrosive gas and steam indoor environment, avoiding direct sunlight and rain.
Keep away from flammable materials: The storage location should be kept away from flammable and explosive materials to ensure safety.
Fixed unit: If conditions permit, the diesel generator can be fixed on the ground or shelves to prevent movement and collision.
6、 Regular inspection and maintenance of diesel generators
Rotate the crankshaft: During storage, the crankshaft should be rotated 1-2 times at regular intervals (such as every month), and after each rotation, the piston should be at the compression top dead center to maintain the smoothness of the lubrication system.
Check the diesel generator: Before and during storage, the appearance, electrical system, and lubrication system of the diesel generator set should be regularly inspected for normal operation. Any abnormalities should be promptly addressed.
By implementing the above measures, diesel generators can be protected from damage during short-term storage, ensuring that they can quickly start and operate normally when needed.
