Water Discharge and Leakage Issues of Diesel Generator Sets

Nov. 21, 2023

Due to the low external environment temperature of the diesel generator set, when the water temperature drops after 15 minutes of shutdown, the cooling water should be discharged, but not immediately. Otherwise, due to the large temperature difference between the body and the external environment, some components of the diesel generator set engine will deform, which will affect the performance of the diesel generator set engine (such as cylinder head deformation).

When draining water, it is not advisable to turn on the drain switch to ensure that everything is in order. It is also important to observe the specific condition of the water flow to see if it is smooth and if there are any signs of water flow decreasing or slowing down. If these situations occur, it indicates that the cooling water contains impurities that hinder the normal flow of water. At this time, it is advisable to remove the drain switch and allow the cooling water to flow directly out of the body.


If the water flow is still not smooth, then hard and slender steel objects such as iron wires should be used to clear the diesel generator set until the water flow is smooth. After the cooling water stops flowing out, shake the diesel generator set for a few more turns. At this time, the remaining and difficult to flow cooling water will flow out completely due to the vibration of the diesel engine, which can prevent the water blockage on the cylinder head from freezing and falling, and the cooling water will flow into the oil shell in the future.


At the same time, it should also be noted that if the drain switch is not removed, after the drain is completed, the drain switch should be in the open state to prevent unnecessary damage to the corresponding components of the diesel engine of the diesel generator set caused by the temporary inability of the remaining cooling water to flow out due to various reasons.
