During the operation of a diesel generator, the influence of its own diesel combustion will cause a sharp increase in the temperature of the diesel engine. High temperature environments will not only affect the improvement of diesel generator working efficiency, but also may suffer. or even cause component failures. Based on this, we need to cool the heated parts, which involves adding coolant to the diesel engine cooling system. What role does coolant play in diesel generator set operation?
First, the antifreeze effect. To ensure that the diesel engine cooling system will not be damaged by freezing when the temperature is too low, generally speaking, the commonly used coolant antifreeze temperature is between minus 20 degrees and 45 degrees, this which can be reasonably selectedselected according to the real needs of the different regions.
Second, the anti-boiling effect. It is guaranteed that premature boiling will not occur under high temperature conditions. The boiling point of commonly used coolant is 104 to 108 degrees. When coolant is added to the cooling system and pressure is generated, its boiling point will be higher.
Third, antiseptic effect. Special coolant can reduce the corrosion of the cooling system, thereby avoiding water leakage problems caused by corrosion of the cooling system.
Fourth, anti-rust effect. High-quality coolant can prevent the cooling system from rusting. Once the cooling system is rusted, it will cause accelerated wear and reduce heat transfer efficiency.
HereFifthly, anti-limescale effect. Since the coolant uses deionized water, it can avoid scale and precipitation and achieve the purpose of engine protection.
Hello, of course you need to add antifreeze. It literally means antifreeze liquid. Its main function is to cool the engine. In winter, its boiling point is 102 degrees. ice. At -35 degrees, its synthesis is mainly ethylene glycol, which has the advantages of antifreeze, anticorrosion and antifouling, so your diesel engine needs to add antifreeze. Thank you
