Possible reasons and solutions for poor air cooler performance:
1. Low cooling water pressure --- increase the water pressure.
2. The cooling water pipe is clogged with foreign objects - clean and clean it.
3. The cooling water temperature is high: this is the most common problem in summer. You may consider using deep well water.
4. The air cooling chamber has a poor seal --- leak.
In addition, you can observe the temperature difference between inlet and outlet water and analyze the cooling effect of the chiller. If the efficiency has reached the standard, it is not a design problem.
How to maintain the cooling system
? Diesel generator water tank is an important component of water-cooled engine as an important component of heat dissipation circuitmics of the water-cooled engine. , it can absorb heat from the cylinder block, to prevent diesel engine from overheating. However, during use, users should pay attention that the water tank of the generator set cannot be without cooling water or add cooling water after starting.
If cooling water is added after the diesel generator set is started, important components such as hot cylinder liner and cylinder head will explode or deform due to sudden combustion and cold. Similarly, if boiling water at 100°C is suddenly added to a cold body, the cylinder head will crack and the body will break.
Yatong reminds everyone that the correct operation method of the diesel generator water tank is: before starting the diesel generator, cooling water should be added first and hot water of around 60°C should beadded to diesel. engine to preheat it before starting.
How to maintain the cooling system
1. It is recommended to use antifreeze.
2. If the radiator is leaking, it needs to be repaired. If the water pump or fan oscillates or makes abnormal noises, it should be repaired in time. If the engine is overheating, you should quickly check for water shortage. If there is a lack of water, stop the engine. After cooling, add sufficient cooling water. If the thermostat does not work properly and makes the engine operating temperature too high or too low, it should be repaired or replaced in time.
3. Improper tension (tightness) of the fan belt will affect the normal operation of the generator and water pump. When the fan belt is too loose, the belt will partially slip into the spleen groove, causing the fan to overheat.motor and will reduce the rate of energy production; when too tight, the belt, generator bearings, and water pump bearings will speed up; to carry.
4. After a certain period of engine use, scale will be deposited in the water tank and radiator, which will affect heat dissipation. Therefore, it must be cleaned regularly. To add enough cleaning fluid to the cooling system and let it soak for a while, start the engine and run it at low and medium speed for a while, then release the cleaning fluid while it is hot , then rinse. with clean water.
The cooling system includes the front fan, radiator, water tank, water pump, water lines, water jacket in the engine and a very important thermostat. When the engine temperature is not high, the cooling waterent only. flows. Low circulation, i.e. water does not pass through the thermostat and radiator. When the water temperature reaches a certain level, the deformed metal in the thermostat opens due to the high temperature. passes through high circulation and passes through the radiator. Ensures normal operation of the cooling system.
