(1) Proper use of closed cooling system
Most engines use a closed cooling system, the radiator cover is 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 large amounts of coolant evaporation loss and increase the boiling point temperature of the coolant. coolant.
The cooling system should use high-quality anti-corrosion, anti-boiling, anti-freeze and anti-scaling coolant, and should be sealed during use to achieve this effect.
(2) Keep the exterior and interior of the cooling system clean
This is one of the important conditions to improve heat dissipation efficiency. When the exterior of the radiator is stained with dirt oroil 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. . Therefore, if the generator radiator is in this situation, it should be cleaned or repaired in time.
In addition, when scale, mud, sand or oil accumulates in the cooling water tank of the generator set, it will affect the heat transfer of the coolant . Adding poor quality coolant or water will cause scale to increase in the cooling system, and the heat transfer capacity of scale is only a few tenths of that of metal, thus worsening the cooling effect. Therefore, high quality coolant should be added to the cooling system.nt.
(3) Keep the amount of coolant sufficient.
When the engine is cold, the coolant level should be between the highest and lowest marks. bottom of the expansion tank if the coolant level is lower. that when the expansion water tank reaches the lowest mark, it should be added in time.
Note that the coolant in the expansion tank cannot be filled completely and there must be room for expansion.
(4) Keep the fan belt tension at a moderate level
If the fan belt is too loose, the water pump speed will be too low, resulting in which will affect the circulation of water. coolant and accelerate belt wear. But if the tape is too tight, it will cause wear on the water pump bearings. Additionally, the tape should not be stained with oil. Consequentlyent, the fan belt tension should be checked and adjusted regularly.
(5) Avoid heavy load operation of diesel generator set
When the engine load is heavy for too long, the coolant temperature will be too high.
(6) Pay attention to good ventilation of the engine room
In particular, the exhaust and smoke discharge of the water tank should be good. The floor must be clean and tidy, and. there should be no oil, dust, etc.
