The weather is cold and the water must be drained when the temperature is below zero. Otherwise, the device will freeze.
Some issues should be considered when waterproofing the diesel generator set:
1 When the external ambient temperature is too low, the cooling water should be drained after 15 minute stop. when the water temperature dropped. This cannot be done immediately, otherwise the temperature difference between the fuselage and the external environment will be too large, causing some parts of the diesel generator set to deform, which will affect the performance of the diesel engine (such as deformation of cylinder head, etc.)
2. When the cooling water stops flowing, it is better to shake the diesel generator several more times. At this time, the remaining cooling water does not flow out. easy to flow will flow due to vibrations of the diesel engine, thus preventing water from blocking the cylinder head. Being frozen, the cooling water will flow into the oil shell 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.
