Would You be Afraid of a Diesel Generator Getting Wet from the Rain

Summer weather is hot, there are many thunderstorms, and diesel generators are often used outdoors, so it is a common phenomenon for diesel generator sets to be drenched by rain.

After the diesel generator was rained out, many users are most worried about the question of whether the diesel generator after being rained out affects power generation. Today Dingbo Power answer this question for you. This is divided into two cases, one case is the diesel generator set did not enter the water, this is relatively simple, only need to use water to rinse off the diesel generator set appearance of dust and impurities. Another situation is the diesel generator set into the water, this situation is slightly more complex, there are the following ways to deal with:

1. Rinse the exterior of the diesel engine with water to remove soil and debris, and then use a metal cleaner or laundry detergent to remove oil from the surface.

2. Support one end of the diesel engine so that the oil pan drain area is at the lowest position. Unscrew the oil drain plug, pull out the oil dipstick, and allow the water in the oil pan to flow out on its own. When the oil is about to be drained, slightly let the oil and water drain together before screwing on the drain plug.

3. Remove the air filter of the generator set, remove the upper shell of the filter, remove the filter element and other components, remove the water from the filter, and clean all parts with metal cleaning agent or diesel. If the filter is made of plastic foam, wash it with detergent or soapy water (gasoline is not allowed), then rinse it with clean water, dry it in the air, and then soak it with appropriate amount of engine oil (squeeze it with your hands after soaking). When installing a new filter, oil immersion should also be performed. The filter element is made of paper and needs to be replaced with a new one. After cleaning and drying all parts of the filter, install them according to regulations.

4. Remove the intake and exhaust pipes and mufflers to drain any internal water. Open the pressure reducing valve, rotate the diesel engine, and check if there is water discharged from the intake and exhaust ports. If there is water discharged, continue to rotate the crankshaft until all water in the cylinder is discharged. Install the intake and exhaust pipes and muffler, add a little engine oil to the intake port, rotate the crankshaft several times, and then install the air filter. If the diesel engine has been flooded for a long time and the flywheel is difficult to rotate, it indicates that the cylinder liner and piston ring have rusted. They should be removed and cleaned before assembly. If the rust is severe, it should be replaced in a timely manner.

5. Remove the fuel tank and drain all the oil and water inside. Check if there is water in the diesel filter and oil pipe, and if there is water, drain it thoroughly. Clean the fuel tank and diesel filter, then reinstall them, connect the oil circuit, and add clean diesel to the fuel tank.

6. Drain the sewage from the water tank and waterway, clean the waterway, and add clean river water or boiled well water until the water float rises. Turn on the throttle switch and start the diesel engine. After starting the diesel engine, it is necessary to observe the rise of the oil indicator and listen for any abnormal noise from the diesel engine. After checking whether all parts are normal, the diesel engine is run in. The running in sequence is to start at idle speed, then at medium speed, and then at high speed, with a running time of 5 minutes each. After running in, stop the machine and drain the oil. Add new engine oil, start the diesel engine, and run it at medium speed for 5 minutes to start normal use.
