There are many reasons why water gets into diesel generators. Here are some summary points of generator maintenance experience:
1 Due to poor maintenance and protection of the unit, water enters the engine block from the engine block. smoke pipe on rainy days or other reasons;
2. The engine room was flooded and the entire unit was submerged in water;
3. The cylinder seal was damaged, and the water in the cylinder water channel entered the oil channel and then flowed into the oil bottom.
4. The water blocking ring of the wet cylinder liner is damaged. In the radiator of the water tank is high and there is pressure, water seeps into the oil circuit along the outer wall of the cylinder liner.
5. The oil cooler is damaged. The oil cooler circulateswater or coolant, or if the oil cooler ruptures, the internal water will flow into the oil circuit and the oil will enter the water tank and mix. .
6. The water pump hydraulic seal is damaged, causing water to enter the oil passage.
7. There are cracks in the engine block or cylinder head. The cylinder block is cracked due to sudden cooling or freezing, and water is seeping through the cracks.

After the engine is flooded, you need to First determine the specific type situation depending on the situation. Take initial corrective action to avoid secondary damage to the vehicle, uncover the key to the problem, and minimize damage to the vehicle.
After understanding the specific situation, if you find that water has entered theengine, you must remove the spark plug and artificially prevent the fuel and ignition system from starting, so that the water in the engine can be successfully drained.
Once the inspection is complete, use compressed air to treat the electrical connections inside the motor to prevent water from corroding them.
The parts to pay attention to are: the fuse box, the sensor socket and the body water accumulation area.
After cleaning, test drive the vehicle to ensure normal engine operation during use.
