The generator set will generate a lot of heat during operation, and the temperature of the diesel engine will also increase. If the temperature of the diesel engine is too high, its working efficiency will be reduced, and even the parts will be burned. Therefore, the generator set needs a cooling system. To cool down and provide a suitable temperature for the normal operation of the diesel engine, coolant needs to be added to the cooling system to assist in cooling down, so what role does the coolant play?
The full name of the coolant for generator set is antifreeze coolant, which is the coolant with antifreeze effect. The coolant has the functions of anti-boiling, anti-freezing, anti-scaling and anti-corrosion. The following is a detailed introduction:
1. Anti-boiling and high temperature protection
When the high-load operating temperature of the generator set is too high, it is ensured that it will not boil prematurely. The national standard for the boiling point of the coolant should not be lower than 106 °C, usually above 108 °C. When the coolant is added to the cooling system and The boiling point will be higher after pressure is created.
With the same mass of water and ice, the volume of ice is larger than that of water. When the temperature is too low, the antifreeze can prevent the coolant from freezing and burst parts and the engine block, ensuring that the generator set is not damaged by freezing.
The cooling liquid is used in circulation. If scale is generated during use, it will block the circulation pipeline, reduce the heat dissipation performance, and even damage the generator set. Coolant scaling can be avoided.
Most of the parts of the generator set are metal products, which are in contact with various liquids and exposed to the air during operation. After a long time, it is easy to corrode and rust, which reduces the service life and performance of the generator set. Therefore, professional coolant Anti-corrosion additives will be added to prevent the cooling system from corroding and rusting.
If the coolant is used for too long, the effect will be greatly reduced, so the coolant must be replaced from time to time to prevent the failure of the coolant and cause the generator set to malfunction. Usually, the coolant is replaced every one to two years, and the cooling should be checked frequently during this period. Whether the system is functioning normally, and if there is a problem, it will be resolved in a timely manner.
