Analysis of water-cooled generator sets.

Analysis of water-cooled generator sets.

Watercooled generator sets use water as the cooling medium to dissipate the generated heat.

Working principle

Because the working principle of generator set is to use water as a cooling medium to absorb the generated heat. So it consists of water pump, water tank, radiator and other components. Then coolant circulates through components such as the engine and alternator. Finally the radiator disperses the heat. So the heat dissipation performance is good. Finally, it can run for a long time.


Because the unit consists of engine, alternator, control system and water cooling system. So the engine is a four-stroke diesel engine. Therefore, the alternator is the core component of the generator set.


High cooling efficiency: Because water-cooled generator set has high heat capacity and thermal conductivity. Therefore, the cooling effect of the generator set is stable and reliable.

Low noise: Because, the water cooling system can absorb most of the engine noise.

Long service life: Because water cooling systems can extend the service life of your equipment.

Suitable for high load and continuous operation. Because of its high cooling efficiency, it is more suitable for high load and continuous operation.


In order to ensure the stable and reliable operation of generator sets. So regular maintenance is necessary.

A. Check coolant level and quality regularly. Clean the cooling system. Change coolant regularly.

b. Check the radiator fins. Then make sure there are no blockages or damage.

C. Clean or replace the air filter regularly.

d. Check the oil level and quality regularly, and replace the oil as required.

e. Check the belt drive tightness and adjust if necessary.

Therefore, maintenance is crucial to the proper operation of the generator set. Finally, it is best to hire professionals for maintenance.
