In the process of using diesel generator set, some scale will be produced in the radiator of diesel engine. If the scale is too much , the sundries will block radiator, and it is easy to ignite incorrectly, which will lead to overheating of generator and decrease of thermal conductivity. 

There will be a certain loss of coolant in the cooling system of diesel generator set, so it is necessary to add water to the cooling system in time. Some users do not add coolant or distilled water, but directly add hard water. As a result, calcium and magnesium ions in hard water can easily form scale with inorganic salt components in ordinary coolant. 

The silica gel scale mainly comes from silicate in the model-free coolant. Metal scale mainly to iron scale and solder scale. The former is mainly composed of inorganic salts in ordinary inorganic coolant, and the protective film formed by reaction with iron metal on the cylinder block is formed by consumption and shedding, while the latter is a strong oxidizing inorganic salt corrosion inhibitor. Aggravation solder "blooming" and the formation of fluffy sediment. Therefore, if the cooling system needs water, not directly add tap water, but need coolant or distilled water.
