Preventing diesel generator cylinder explosion in winter and solutions

When the temperature is low in winter, the cylinder head of a diesel generator is very easy to explode. Therefore, the following methods hope to help everyone.

1. Add cold water after starting. After the diesel engine starts, the temperature inside the diesel generator rises. If cold water is added, the cylinder block and cylinder head will cool down rapidly, which will cause cracks due to cold shrinkage.

2. After shutting down, if the cooling water is not discharged, the inside of the machine will freeze into ice, increase in volume, and cause the cylinder block and cylinder head to swell and crack.

3. When the engine is operating, there is a shortage of cooling water or the water tank boiler temperature is too high. If cooling water is suddenly added, the cylinder block and cylinder head will be overcooled and shortened, which will also cause cracks.

4. The generator set has been operating for a long time, and the temperature inside the machine is high. If the high-temperature water is drained immediately after parking, the high-temperature parts will suddenly encounter cold air and crack.

5. Use decompression shutdown to cause the high-temperature cylinder head to suddenly encounter cold air and cause cracks.

Here are some ways to avoid cracking of various types of cylinder blocks and cylinder heads:

1. Before starting the diesel engine, warm water should be added to the water tank.

2. When the diesel engine operates for a long time, you should wait for about half an hour after shutting down. When the engine temperature drops to 40-50 degrees, add cold water.

3. When the diesel generator overheats and is seriously short of water, the diesel engine should be allowed to idle slowly for 10-15 minutes, and then gradually add cooling water.

I have introduced a lot to you, and I hope it can help you. In your daily life, pay attention to the detailed operation and maintenance, thereby extending the life of the diesel generator.
