During long-term operation, diesel generator sets may be affected by factors such as wear, carbon deposition, and oil pollution, leading to performance degradation or even failure. Regular maintenance can effectively prevent these problems and extend the lifespan of the generator set. Meihua Power editor has compiled articles on the maintenance of diesel generator sets for your reference:

1. Oil and filter replacement

Engine oil can be compared to the "blood" of the engine. Regularly changing the oil and filter can ensure good lubrication inside the engine and reduce wear. It is recommended to change the oil and filter every 250-500 hours of operation or every 6 months.

2. Fuel system maintenance

The cleanliness of the fuel system directly affects the operational efficiency of the generator set. Regularly clean the fuel filter and inspect the fuel lines to prevent impurities from entering the engine and to avoid blockages in the fuel injection system.

3. Maintenance of cooling system

The cooling system is the key to preventing engine overheating. Regularly check the coolant level, clean the dust and debris on the surface of the radiator, and ensure the normal operation of the cooling system.

4. Battery inspection and charging

The battery is a key component for starting a generator set. Regularly check the electrolyte level of the battery, clean the electrode joints, and ensure that the battery is fully charged to avoid startup failure caused by battery problems.

5. Cleaning and replacement of air filter

The function of an air filter is to filter out dust and impurities from the air entering the engine. Regularly cleaning or replacing the air filter can prevent poor engine intake and affect combustion efficiency.

6. Run testing and load testing

Regularly conduct no-load and load tests to check the output voltage, frequency, and load capacity of the generator set, ensuring that the equipment can supply power normally in emergency situations.
