During operation, diesel generators often experience high temperatures. Prolonged exposure to high temperatures is extremely detrimental to the machinery. Typically, operators resort to injecting cold water to cool down the engine. But are there any other methods? Let me tell you—another effective option is to use coolant. So, what exactly are the effects and functions of coolant? 1. Antifreeze: In extremely low-temperature conditions, coolant ensures that the vehicle’s cooling system won’t freeze and get damaged. Generally, commonly used antifreeze solutions have freezing points ranging from -20°C to -45°C. The specific freezing point is usually chosen appropriately based on the actual needs of different regions to meet operational requirements. 2. Anti-boil: Under high-temperature conditions, coolant prevents the cooling system from boiling prematurely. Commonly used coolant...
During operation, diesel generators often experience high temperatures. Prolonged exposure to high temperatures is extremely harmful to the machinery. Typically, operators address this by injecting cold water to cool down the system. But are there any other methods? Let me tell you—another effective approach is to use coolant. So, what exactly are the effects and benefits of using coolant?
1. Antifreeze: In conditions of extremely low temperatures, antifreeze ensures that the vehicle’s cooling system is protected from freezing damage. Generally, the freezing point of commonly used antifreeze solutions ranges from -20°C to -45°C. The appropriate choice often depends on the specific needs of different regions to meet operational requirements.
2. Boil Prevention: Under high-temperature conditions, it ensures that the coolant does not boil prematurely. Typically, commonly used antifreeze solutions have boiling points ranging from 104°C to 108°C. Once the antifreeze is added to the cooling system and pressure is generated, the boiling point will further increase. 3. Corrosion Prevention: Specialized antifreeze solutions can reduce corrosion in the cooling system, thereby minimizing the risk of “leaks” caused by rust formation in the cooling system.
4. Rust prevention: High-quality antifreeze can prevent rust from forming in the cooling system. If the cooling system rusts, it can lead to accelerated wear and reduced efficiency in heat transfer.
5. Anti-scale: Since the coolant uses deionized water, it can prevent the formation of scale and sediment, thereby protecting the engine.
6. Problems that may arise from infrequent replacement of antifreeze: If antifreeze is left unchanged for an extended period, its corrosion-inhibiting, rust-preventing, and scale-inhibiting properties will gradually diminish, potentially leading to cooling system malfunctions or even rust formation. As a general rule, antifreeze should be replaced every 1.5 to 2 years.
