The so-called "boiling" of a gasoline generator means that the water in the water tank of the gasoline engine, the main engine of the gasoline generator, has boiled. At this time, a large amount of water vapor will emerge from the water tank cover, which is easy to see, which is a warning signal to the machine owner.
If this situation occurs and you do not stop the car immediately, the following consequences will occur:
1. The cooling water in the water tank continues to evaporate, resulting in a "dry pot";
2. There is no circulation of cooling water in the cylinder liner;
3. Heat from the cylinder wall is no longer carried away by the water, and the temperature continues to rise;
4. Lubricating oil deteriorates due to high temperature and loses its lubricating and cooling effects. The friction around the piston andof the cylinder wall increases rapidly, causing "cylinder pull", or even "cylinder pull". holding the cylinder", which in turn damages the crankshaft bearing and causes bending of the connecting rod.
What is wrong with water at the bottom of a ship's generator inlet ?
The radiator or expansion tank of the diesel generator has serious water and steam leaks. This is usually caused by the proximity of the cylinder. at the water jacket hole is damaged, causing the combustion chamber to communicate with 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 water vapor to overflow from the overflow pipe of the water filling cover and thebreather 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 tightening torque of the cylinder head bolts is insufficient, or the bolts used have been elongated and deformed and have failed to compress the cylinder seal.
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.

cy shirt leaklindre, damage to the cooler, etc.
1. The cylinder liner is leaking. The cylinder liner seal ring is not good and leaking.
2. The cooler is damaged. The oil cooler is damaged and some of the cooling water leaks into the lubrication system.
3. The water pump is getting old. The hydraulic seal and mechanical seal of the cooling water pump are aged or damaged, and cooling water enters the lubrication system.
