The maintenance cycle of the radiator of the diesel generator set is once every 200 hours of operation.
Exterior cleaning: spray with hot water (adding detergent) from the front of the radiator toward the fan (if you spray from the opposite direction, it will only push the dirt closer to the center), use this method When cleaning, use tape to block the diesel generator. If the above methods cannot remove stubborn sediments, the radiator should be removed and immersed in hot alkaline water for about 20 minutes, and then cleaned with hot water.
Internal descaling: 1. Drain the water from the radiator, then disassemble and seal the connection between the radiator and the pipe; 2. Pour 4% acid at 45 degrees into the radiator solution, drain the acid solution after 15 minutes, and check the radiator; 3. If there is still scale in the cleavage, wash it again with 8% acid solution; 4. After descaling, neutralize it twice with 3% alkali solution, and then Then rinse with clean water for more than three times; 5. After all work is completed, check whether the radiator is leaking. If it is leaking, apply for outsourcing repair. 6. If it is not leaking, reinstall it. After the radiator is installed, it should be refilled with clean water and added Rust inhibitor.

Okay.
1. A closed generator refers to a generator that is sealed inside and usually equipped with a cooling system on the outside to reduce the temperature through air or liquid circulation to prevent failure caused by overheating.
2. An open radiator refers to a radiator without a cover. It uses natural air cooling or forced air cooling to dissipate heat through the air to the heat exchange tubes on the surface of the heat exchanger to reduce the operating temperature. .
