Under what circumstances does a diesel generator explode?

Diesel generators will not explode, but cylinder explosions will occur. Here are the causes of cylinder explosions and how to avoid them:

1. Use a pressure reducer to stop the engine, so that the engine explodes. the high temperature cylinder head suddenly encounters intense cold air which may cause cracks.

2. After shutdown, the cooling water was not discharged. The water in the machine turns into ice and increases in volume, causing the cylinder block and cylinder head to burst.

3. The generator runs for a long time and the temperature inside the generator is high. Drain high temperature water immediately after parking. High temperature parts are likely to crack when suddenly encountering cold air.

4. When the generator set is running, there is a lack of cooling water or the boiler temperaturere of the water tank is too high and cooling water is suddenly added. Overcooling and shortening of the cylinder block and cylinder head can also lead to cracking.

5. Add cooling water after start-up. After starting the diesel engine, the temperature inside the diesel generator increases immediately. If cooling water is added at this time, the cylinder block and cylinder head will cool quickly, causing cold shrinkage cracks.

Methods for diesel generators to prevent cracking of various cylinder blocks and cylinder heads:

1. When the generator is overheated and severely short of water, the diesel engine must idle. low speed for 10 to 15 minutes. Then gradually add cooling water

2. Before starting the diesel engine, warm water should be added to the water tank. In harsh winter,hot water should be refilled 2-3 times until the water tank is filled with hot water. The water flowing out of the drain tap is around 30 to 50°C. Better start.

3. When the diesel engine runs for a long time, you should wait about half an hour after stopping, and then drain the cooling water when the engine temperature drops to 40~50℃. After draining the water, it is best to use a fine wire to pierce the drain valve switch to prevent sediment from blocking the drain valve.
