1.Add cooling water after starting. After the diesel engine is started, the temperature inside the machine rises immediately. If the cooling water is added at this time, the cylinder block and the cylinder head are cooled rapidly, and the air is cracked due to shrinkage.
2.After the shutdown, no cooling water is placed. The water in the machine freezes into ice, and the volume increases, causing the cylinder block and the cylinder head to burst.
3.When the diesel engine is running, the cooling water is insufficient or the temperature of the water tank opener is too high, and the cooling water is suddenly added. Subcooling shrinkage of the cylinder block and cylinder head can also cause cracking.
4.The diesel engine runs for a long time, and the temperature inside the machine is high. How to prevent the generator set from being frozen and immediately discharge the high temperature water after stopping the power generation. It can cause hot parts to crack in cold air.
5.Use the pressure reducer to stop, so that the high temperature cylinder head suddenly encounters cold air and causes cracking.
