The core solution for
diesel generator sets soaked in water is to immediately stop running, drain and inspect for damage, and replace damaged parts if necessary.
Firstly, stopping the operation immediately is the primary step. Once water is found in the diesel generator, it should be immediately stopped and all power and loads should be disconnected to prevent further damage to the engine and electrical system.
Next, drainage treatment is a crucial step. The water inside the generator set needs to be drained, and manual or automatic drainage systems can be used. If the drainage is not thorough, the engine needs to be disassembled and the water manually drained. The specific operations include:
Lift up one end of the diesel generator so that the oil pan drain is in a lower position, unscrew the drain plug, pull out the dipstick, and allow the water in the oil pan to flow out on its own.
Remove the air filter, remove the accumulated water inside, and clean all parts with cleaning agent or diesel.
Remove the intake and exhaust pipes as well as the muffler, remove any internal water, and rotate the diesel engine until all water in the cylinder is completely drained.
Remove the fuel tank, drain all the oil and water from it, clean the fuel tank and diesel filter, then reinstall them and connect the oil circuit.
Checking for damage is also an important step. Open the oil pan and valve cover, and check the condition of the oil and coolant. If the engine oil turns milky white or the coolant contains engine oil, it indicates that water has entered the engine interior. Check for damage to key components such as the intake system and electrical system.
Finally, replace the damaged parts and perform maintenance. If engine components such as cylinder block, cylinder head, crankshaft, etc. are found to be corroded or damaged, they need to be replaced accordingly. At the same time, maintain the engine, including changing the oil, oil filter, air filter, etc., to prevent further damage to the engine caused by water.
By following the above steps, the problem of diesel generator sets flooding can be effectively addressed to ensure its normal operation is restored.
