How to Clean Radiator of Diesel Generator Set

Dec. 26, 2020


The radiator plays an important role in ensuring the normal operation of the diesel generator set. If it is not used properly, it will damage the diesel engine and generator set. If it is more serious, it may lead to the scrapping of the diesel engine. 


Regular maintenance can ensure radiator work normally. Today Starlight Power mainly talks about the clean methods of radiator, hope this article is helpful to you.


How to clean radiator in diesel generator set?


After a long term use of radiator, the most important is to clean it. Radiator cleaning is divided into external cleaning and internal cleaning. This is a very important link, which will directly affect the use effect of the radiator, and then affect the use of the whole generator set.

 

The gap of the radiator of generator set working in the open air may be blocked by debris, insects and other debris. We can often use low-pressure hot water (appropriate addition of cleaning agent) for spray washing, pay attention to the steam or water from the front of the radiator to the fan spray. When spraying, cover the diesel engine and alternator with cloth. If the deposit is difficult to remove, remove the radiator and soak it in hot alkaline water for about 20 minutes, then rinse it with hot water.

The radiator of diesel generator set will produce scale when it is used for a long time. In order to ensure the heat dissipation effect of cooling system of diesel generator set, we need to clean the water tank of diesel generator set regularly. The radiator of Starlight Power usually use Wei Chuang brand, here Starlight Power tell you how to clean it.


Firstly, pour 30kg water, 2.5kg caustic soda and 0.6kg kerosene into the water tank.


Secondly, start the diesel generator set. Turn off the diesel generator set after running at medium speed for about 10 minutes. After 10-12 hours, start the diesel generator set again, and stop the engine after running at medium speed for about 10 minutes.


Finally, control the cleaning liquid in the water tank, add clean cooling water, start the diesel generator set, operate at medium speed to make the diesel generator set clean by itself, and repeat 2-3 times to remove the scale in the water tank of the diesel generator set.

 

In order to ensure the service life of the diesel generator set and reduce the failure rate, we should regularly maintain the diesel generator set. And we should also pay attentions below:

 

During the operation of the generator set, the coolant in the cooling radiator is usually very hot and has pressure. Therefore, it is strictly forbidden to clean the radiator or remove the pipe when it is not cooled, let alone operate the radiator or open the fan protective cover when the fan is rotating.

 

Corrosion is the main cause of radiator failure. It is suggested that the pipe joints should be checked frequently to avoid leakage, and the water tank should be filled regularly to drain the air in the system. The cooling water tank should not be in the condition of partial water injection and discharge, because it often accelerates the corrosion process. For the generator set that doesn't work, the water tank should be emptied or filled completely. If conditions permit, it is best to use distilled water or natural soft water, and add an appropriate amount of antirust agent.

 

What is the function of radiator in diesel generator set?

 

1.The air inlet baffle and louver should be able to adjust the gas flow during operation (for example, the louver assembly with narrow blades has greater resistance than that with wide blades).

 

2.When the generator operates in cold climate, the air intake valve of diesel engine should be closed. When the diesel generator starts, all the inlet and outlet on-off valves should be opened; when the air temperature is higher than 16℃, all the circulation control valves should be closed.

 

3.Except that the cooling air is allowed to be recycled in the machine room in the cold climate, the rest of the ventilation air should be directly discharged to the outside, and it is strictly prohibited to heat other rooms (except the generator room).

 

4.Radiator is necessary to use elastic pipe joint to absorb displacement and vibration of diesel generator set. Regularly check the technical status of front wheel alignment and steering device. Regular inspection and adjustment of front wheel alignment, front wheel bearing clearance and steering device is an important measure to reduce tire wear and deformation damage of walking parts. Check according to the required value of each type of tractor and adjust it if necessary. Pay more attention to the fixed clearance of the front wheel knuckle and the tie rod nut, especially the front wheel.

 

5.The daily maintenance of diesel generator is very important. Keep all parts clean, and check the fastening of hub bolts, nuts, split pins and other parts frequently to ensure the fastening is reliable. Add grease to the swing shaft sleeve, front wheel shaft and steering knuckle every shift; regularly check the oil level of belt pulley, guide wheel and supporting wheel, add lubricating oil if necessary, and regularly clean and change the oil as required. Only in this way can the service life of generator set be improved.

 

6.In order to reduce the noise of the fan and the bad influence of the external wind, the baffle should be added near the ventilation inlet and outlet.
