What Is the Function of Breather and Radiator in Diesel Generator?
Breather
Due to the continuous operation of any diesel engine the lubrication oil gets high temperature due to which there will be oil vaporization and this vapor can not be allowed to remain inside the crank case which may get high pressure and therefore the breather or pipe is provided to send it out to atmosphere to keep safe engine operation.
Radiator
A generating set is usually a internal combustion engine mechanically driving an AC alternator or DC dynamo. The most common type of genset would be a diesel engine or AC alternator used as a AC power generator, could be a primary power source or secondary source i.e a back up AC power source for important building like hospital etc.
Thus most of these diesel engines are water cooled and would need a radiator to cool the engine via the engine coolant being pumped through the radiator, much like many cars. The radiator usually will have a fan blowing air through the radiator vanes to improve cooling effect.
Maintenance of Diesel Generator Radiator
1. Usually, corrosion is the main cause for radiator failure. In the process of using, the air in the water will accelerate the corrosion process. Therefore, doing a regular maintenance for the pipe joint is quite necessary to avoid leaking. Meanwhile, do not forget to regularly add water to drain air from the top of the radiator.
Attention: Radiators should not be partially injected with water, which will speed up corrosion. For non-working generating sets, water should be completely removed or fully filled. If possible, please use distilled water or natural soft water and add appropriate amount of antirust agent.
2. Coolant of the working radiator is usually very hot and with pressure, you are not allowed to tidy the radiator or dismantle the pipes before cooling; do not work on the radiator or open the protection cover while the fan is till rotating.
3. Outside cleaning: In a dusty or polluted environment, the gap of the radiator may be jammed by fragments or insects, which will affect the efficiency of the radiator. Regular cleaning of these light deposits can be done with low pressure hot water and detergent. Spray steam or water from the front of the radiator to the fan. It is from the opposite direction, the dirt will be blow into the center. When using this method, diesel engine and AC generator should be covered with cloth. For stubborn sediments, removal can not be done by up-mentioned method. Please disassemble the radiator and soak it in the hot alkaline water for about 20 minutes, then wash it with hot water.
