Maintenance of Enclosed Cooling Device of Diesel Generator Set

Most of the modern diesel engine closed cooling devices of diesel generator set manufacturers use closed cooling, the radiator cover is sealed, and an expansion water tank is added. When the engine is working, the coolant vapor enters the expansion tank and flows back to the radiator after cooling, which can prevent a large amount of evaporative loss of the coolant and increase the boiling point temperature of the coolant. The cooling system should use high-quality coolant with anti-corrosion, anti-boiling, anti-freezing and anti-scaling, and must be sealed during use to receive results.

Dingbo Power Equipment believes that it is very important to keep the outside and inside of the diesel generator set cooling system clean. This is one of the important conditions for improving heat dissipation efficiency. When the outside of the radiator is stained with dirt, oil, or the heat sink is deformed due to collision, it will affect the passage of the wind, and the heat dissipation effect of the radiator will deteriorate, causing the coolant temperature to be too high. Therefore, it is found that the radiator of the diesel generator set should be cleaned or repaired in time.

In addition, when scale, mud sand or oil dirt accumulates in the cooling water tank of the diesel generator set, it will affect the heat transfer of the cooling liquid. Filling with inferior coolant or water will increase the scale of the cooling system, and the heat transfer capacity of the scale is only a few tenths of that of the metal, so the cooling effect will be poor. Therefore, the cooling system should be filled with high-quality coolant.

Dingbo Power Equipment reminds the user that the most important thing is to keep sufficient coolant in the diesel generator set. When the engine is cold, the coolant level should be between the highest and lowest marks of the expansion tank, if the liquid level is lower than the lowest mark of the expansion tank should be added in time.

Dingbo Power was founded in 2006 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
