How to drain water from diesel generator water tank

How to drain the water tank of the diesel generator. Generator manufacturers believe that because the external ambient temperature is too low, the cooling water should be discharged after 15 minutes of shutdown when the water temperature has dropped, not immediately, otherwise the temperature difference between the fuselage and the external environment will be too important. , causing the diesel generator to fail. Some parts of the unit are deformed, which in turn affects the performance of the diesel engine (such as cylinder head deformation, etc.). When the cooling water stops flowing, it is best to shake the diesel generator several times. At that time, the remaining cooling water that does not flow easily will flow out due to the vibration of the diesel engine. can prevent the water on the cylinder head from freezing. If it falls, cooling water will flow into the engine oil pan. The operator must also notter 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 cooling water The remaining water cannot temporarily flow for various reasons and freezes. the corresponding parts of the diesel engine. Generator manufacturers remind users not to activate the water release switch and everything will be fine when releasing the water. They also need to pay attention to the specific water flow conditions to see if the water flow is steady and whether it is getting smaller. or faster and slower. If these conditions occur, it means that the cooling water contains impurities that hinder the normal flow of water. At this point, it is best to remove the water drain switch and let the cooling water flow directly from the body. If the water flow is still not regular, uUse hard, thin steel objects such as wire to dredge it until the water flow is steady.

The diesel generator's radiator or expansion tank is leaking violently with water and steam. This phenomenon is usually caused by damage to the cylinder seal near the cylinder water jacket hole, causing communication with the combustion chamber. the water channel. When the piston moves upward for compression or combustion, the high pressure gas in the cylinder rushes into the water channel from the damaged area of ​​the cylinder seal, causing a large amount of steam to overflow from the overflow pipe to the water fill cover and the breather valve. In severe cases, water will be sucked in with the intake stroke cylinder, causing the engine to shut down. Of course, the coolant will decrease accordingly.

Cause of failure :

① The cylinder head is uneven, the cylinder head bolts have insufficient torque, or the bolts used have been elongated and deformed and have failed to compress the cylinder gasket.

② There are blisters, cavitation and other defects in the water channel adjacent to the cylinder block or cylinder head and combustion chamber, causing transparency.

③ When the temperature is too high, cold water is suddenly added to cause cracks in the water passages of the cylinder block or cylinder head, causing high pressure gas to leak in water passages.
