1. Do not add water during operation
You should know that it is not recommended to add water during operation of the diesel generator after starting the engine, because it does not There is no cooling water inside. The temperature of the water jacket outside the cylinder head and injector of the diesel engine is particularly high. If cooling water is added at this time, the cylinder head and water jacket will heat up quickly. Easily crack or deform due to sudden cooling. 2. Precautions when adding water during shutdown (1) Heating water in winter. During the cold winter, it is difficult to start the generator. If cold water is added before starting, it is easy to freeze in the lower chamber of the water tank and in the water inlet pipe during the water filling process or when the water is added but fails to start. be started attime, preventing water from circulating, it can even cause the water tank to burst. Adding hot water can, on the one hand, increase the engine temperature (2) Add clean, soft water. After filling the water tank with antifreeze, if you find that the liquid level in the water tank has dropped, simply add fresh, clean water (distilled water is best) assuming that there is no leak, because the boiling point of commonly used ethylene glycol antifreeze is high, what evaporates is the water contained in antifreeze, it is not necessary to replenish the antifreeze but only fresh water. It’s worth mentioning: never add unsoftened hard water. (3) Fresh water selection. Fresh water generally includes rain water, snow water, river water, etc. This water contains few minerals and is suitable for engine use. The added water must be clean. Impurities coHeld in water will block the water channels and cause increased wear on the water pump impeller and other components. If hard water is used, it must be softened first. Softening methods typically include heating and adding lye (usually caustic soda).
