A diesel generator set is a combination of a diesel engine and a generator, which drives the generator to generate electricity through the diesel engine. However, both the diesel engine and the generator need maintenance and cold protection work in this snowy winter. So how to carry out maintenance?
1. Replace fuel
Nowadays, diesel on the market can be used for different temperatures depending on the brand. Therefore, before winter arrives, it is necessary to understand how low the local winter temperature was in previous years, and then choose diesel that is suitable for temperatures 3 to 5 ℃ lower than the minimum temperature. Generally, diesel suitable for winter has a low temperature ranging from minus 29 ℃ to above 8 ℃, and can be selected according to needs.
2. Use antifreeze
Antifreeze can effectively operate diesel generator sets in winter, and usually choose antifreeze with a freezing point 10 ℃ lower than the local minimum temperature. Antifreeze generally has a color that can be detected in a timely manner when there is a leak. Once discovered, the leak should be wiped dry and the leak should be inspected for timely repair. Another thing is to regularly replace the antifreeze to prevent it from becoming ineffective.
3. Change the engine oil
The engine oil at room temperature is different from the engine oil at colder temperatures. Engine oil at room temperature will experience increased viscosity and friction in cold winter, which will affect the engine's rotation and increase fuel consumption. Therefore, it is necessary to replace the winter specific engine oil. However, winter engine oil cannot be used at room temperature because the oil used in winter at room temperature may fail and cause equipment malfunction.
4. Replace the filter element
The air in winter is relatively thin, dry, and cold, and ground dust is dispersed in the air due to mechanical vibration. Therefore, the air filter element of diesel generator sets is very important and needs to be replaced more frequently. Otherwise, the dust in the air not only affects the purity and combustion of the oil, but also may enter the cylinder and wear equipment.
5. Preheating work
Just like a car, when the external air is cold, starting the diesel generator set requires running it at low speed for 3 to 5 minutes to raise the overall temperature before inspection. Only when everything is normal can it be used normally. Otherwise, after the cold air enters the cylinder, the compressed gas is difficult to reach the natural temperature of diesel; At the same time, sudden acceleration operations should be reduced during operation, otherwise it will affect the service life of the valve components.
