Diesel generator sets generate high temperature due to the combustion of diesel during operation. In order to ensure that the heated parts of the diesel generator set and the shell of the supercharger are not affected by the high temperature, and to ensure the lubrication of each working surface, the heated parts must be cooled.
Poor cooling of diesel generator sets and excessively high temperatures will cause some failures. Diesel engine parts should not be cooled too much, too low temperature will cause bad consequences. It can be seen that the role of the cooling system is to transfer part of the heat from each heated component to keep the component at a normal working temperature.
There are two types of cooling methods for diesel generators: water cooling and air cooling. The water cooling method uses water to cool the cylinder, and the air cooling method uses air to cool the cylinder. One of the water-cooled units is a closed self-circulating water-cooled unit. It is from the radiator water tank to the water pump to the water-cooled cavity of the diesel engine body, and then returns to the radiator water tank. Open circulation cooling unit.
In high-rise buildings, in general, an integrated unit with closed water circulation cooling should be selected, which occupies a small area and space.
