The water tank is the heat dissipation device of the diesel generator set, which plays a big role in heat dissipation. Users are advised to pay special attention to the use of the water tank. The diesel generator water tank will produce scale during use. If there is too much scale in the water tank, the sundries will block the water tank, and it is easy to ignite incorrectly and reduce heat dissipation, which will lead to overheating of the generator set, thereby reducing the service life of the diesel generator set. Therefore, remove the scale in the water tank of the diesel generator set in time to ensure the normal operation of the diesel generator set. So, do you know that the scale in the water tank of the diesel generator set is the cause?
The cooling system of the diesel engine generator set will have a certain loss of coolant during use, and it is necessary to add water to the cooling system in time. The water used in the water tank is also different, try to use soft water. What is soft water? Soft water refers to water such as rain or snow and river water. These waters contain less minerals and are suitable for generators. And those well water and tap water contain high minerals.
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 salts in ordinary coolant. Silica scale mainly comes from silicates in inorganic coolants. Metal scale is mainly iron scale and solder scale. The former is mainly formed by the protective film formed by the reaction between the inorganic salt in the ordinary inorganic cooling liquid and the iron metal on the cylinder body due to consumption and falling off, while the latter is caused by the strong oxidizing inorganic salt corrosion inhibitor aggravating the “blooming” of the solder. The fluffy sediment formed.
It can be seen from this that the formation of scale in the water tank of the diesel generator set is mainly due to the improper use of the generator cooling system, and will have serious consequences for the normal operation of the generator set. In order to ensure the heat dissipation effect of the diesel engine cooling system, make the diesel engine work normally, and increase the service life of the diesel engine, the dirt in the water tank of the diesel engine should be cleared in time.
How to remove the scale in the water tank of the diesel generator set? The specific operation method given by the generator set manufacturer is: first, use 30 kg of water, 2.5 kg of caustic soda, and 0.6 kg of kerosene to prepare a cleaning solution and pour it into the water tank. Then start the diesel engine, run it at medium speed for about 10 minutes and then turn off the engine. After 10 to 12 hours, restart the diesel engine, run at medium speed for about 10 minutes, turn off the engine, and release the cleaning fluid. After adding clean cooling water, start the diesel engine and run at medium speed to clean it by itself. Repeat this 2 to 3 times to completely remove the scale. After washing the scale in this way, this is only a temporary solution, and it is best to add antifreeze and rust inhibitor to the cooling water to prevent the formation of scale.
In short, once you find that the scale has accumulated in the water tank of the diesel generator set, it should be cleaned and removed in time to avoid irreparable accidents to the operation of the diesel generator set.
