How to drain the 50kw diesel generator?

Introduction How to drain the 50kw diesel generator? When draining the water of the diesel generator set, please pay attention to the following points: 1. When the external ambient temperature is too low, drain the cooling water after stopping for 15 minutes.

How to drain the 50kw diesel generator?

Particular attention should be paid to draining the water of the diesel generator set: 1. When the external ambient temperature is too low, draining the cooling water should be carried out after 15 minutes of stopping when the water temperature dropped, but not immediately. otherwise, there will be a gap between the fuselage and the exterior. The temperature difference in the environment is too large, causing some parts of the diesel generator set to be deformed, which in turn affects the performance of the diesel engine (such as cylinder head deformation). , etc.) 2. After the cooling water stops flowing, it is better to shake the diesel generator a few more times. At this time, the remaining cooling water that is difficult to flow will flow out due to the vibration of the diesel engine. This can prevent the water blockage on the cylinder head from freezing and the cooling water will flow into the oil shell.engine island in the future. The operator should also note that if the water drain switch is not removed, the water drain switch must be in the open state after water draining is completed to avoid the remaining cooling water cannot flow temporarily for various reasons and freezes. the corresponding parts of the diesel engine.

1 Do not add water during operation

You should know this in. diesel generators It is not recommended to add water during operation. After starting the engine, because there is no cooling water in the body, the engine parts heat up quickly, especially the water jacket outside the cylinder head et the injector of the diesel engine. the temperature is particularly high. If water is added at this time, the cooling water, cylinder head and water jacket are prone to cracking or deformation 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 in time, preventing water from circulating, it may 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 notice that the fluid level in the water tank iswater has gone down, just add clean, fresh water (distilled water is best) assuming there are no leaks, because the boiling point of antifreeze to commonly used ethylene glycol is high, what evaporates is the water in the antifreeze, there is no need 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 in the water will block the water channels and worsen the wear of 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).eu).
