Due to structural constraints, diesel generators can’t be completely waterproof. When the rainy season season comes, generators may be affected by natural disasters such as floods and rainstorms. When water enters the generator, you should take necessary measures to disconnect the external power supply and the battery connection line, prohibit running the engine, and check the water ingress of each part.
Water enters the generator FAQ
- Check the exhaust pipe to see if there is water discharged from the drainage component.
- Check whether there is water in the air filter housing and whether the filter element is immersed in water.
- Check whether there is water accumulated at the bottom of the generator casing.
- Check radiator, fan, and coupling for blockage.
- Whether there is leakage of organic oil, fuel or water from the outside.
- Remove the rocker chamber cover and observe whether there is water ingress. Check the insulation and ontamination of the generator windings.
- Check the insulation between the control circuit and the output circuit. Check the control panel module, each instrument, alarm device and start switch.
Note: Never let water enter the combustion chamber of the engine!
Treatment after water enters the generator:
When confirm there is no water in the combustion chamber and the insulation meets the requirements,can start the generator. Pay attention to the following issues when starting:
- Do all inspections before starting, including draining water in the fuel tank. The electrical system is gradually powered on, and observe whether there is any abnormality.
- Start the engine continuously shall not exceed 30 seconds. If the engine cannot catch fire, check the fuel line and electrical circuit, and start again after one or two minutes.
- Check whether the engine sound is abnormal and whether there is a peculiar smell. Check whether the display of the electrical instrument and the LCD screen are broken or unclear.
- Closely observe the oil pressure and water temperature. If the oil pressure or temperature does not meet the technical specifications, the engine should be shut down. After stopping, check the oil level.
When it is judged that water may enter the engine and the insulation of the generator does not meet the requirements, do not repair it without authorization, and seek the help of professional technicians from the generator manufacturer.
