Seven important points to consider to avoid excessive temperature of diesel generator sets in summer:
1. Maintain sufficient coolant quantity. When the engine is cold, the coolant level should be at its highest. and the lowest levels of the expansion tank. Between the marks, if the liquid level is lower than the lowest mark of the expansion tank, add it in time.
2. Avoid the diesel generator set working under heavy load for a long time. If the engine load is too high for a long time, the coolant temperature will be too high.
3. Pay attention to good ventilation in the computer room
4. Sufficient lubrication of the cooling fan pulley shaft can prevent its aging.
5. Coolant should use qualified tap watere, preferably distilled water, demineralized water or pure water.
6. Use the generator set's closed cooling system correctly. Most diesel engines now use a closed cooling system. The radiator covers are sealed and an expansion tank is added. When the engine is running, the coolant vapor enters the expansion tank and returns to the radiator after cooling, which can prevent a large amount of coolant evaporation loss and increase the boiling point temperature of the coolant. cooling liquid.
7. Keep the inside and outside of the cooling system clean. Cleaning the cooling system is one of the important conditions to improve heat dissipation efficiency. If the exterior of the radiator is stained with dirt or oil or the radiator fins are deformed due to collision, the wind passage will be affected and the heat dissipation effect of the radiator will worsen, resulting in the coolant temperature being too high. .
