1. Antifreeze, to ensure that the vehicle's cooling system does not freeze when the temperature is too low. Generally speaking, the temperature of commonly used antifreeze is between minus 20 degrees and 45 degrees. the actual needs of different regions to meet application requirements.
2. Anti-boil: It ensures that it will not boil prematurely under high temperature conditions. The boiling point of commonly used antifreeze is between 104 degrees and 108 degrees when the antifreeze joins the cooling system and generates. pressure, the boiling point will be higher. 3. Anti-corrosion: Special antifreeze can reduce the corrosion of the cooling system, thereby reducing the problem of "water leakage" caused by corrosion of the cooling system.
4. Rustproof. High-quality antifreeze can prevent the cooling system from rusting, which will lead to increased wear.and reduced heat transfer efficiency.
5. Anti-scaling: Since the coolant uses deionized water, it can prevent the formation of scale and precipitation, thereby protecting the engine.
6. Problems that may result from irregular antifreeze replacement: If antifreeze is not replaced for a long time, the anti-corrosion, anti-rust and anti-scaling functions will be reduced, which may cause cooling system failure or even corrosion. Generally speaking, antifreeze is replaced every 1.5 to 2 years.
Differentdiesel generatorsmanufacturers and different power diesel generators use different oils. Normally, a new engine runs for 50 hours for the first time and 50 hours after repair or overhaul.
The oil change cycle usually occurs at the same time as the oil filteroil (filter element). The general oil change interval is 250 hours or one month. With Category 2 engine oil, the oil can be changed after 400 hours of operation, but the oil filter (filter element) must be replaced.
Function of diesel generator oil
1. Sealing and leak prevention: Oil can form a sealing ring between the piston ring and the piston to reduce gas leakage and prevent external pollutants from entering. .
2. Anti-rust and anti-corrosion: The lubricating oil will be sucked into the surface of the parts to prevent water, air, acidic substances and harmful gases from contacting the parts.
3. Lubrication and wear reduction: Rapid relative sliding between piston and cylinder and between main shaft and bearing. To prevent excessive wear of the parts, a film of oil is necessary between the two sliding surfaces. A film of huIsland of sufficient thickness separates the surfaces of opposing sliding parts to reduce wear.
4. Cleaning: High quality engine oil can carry carbides, sludge and worn metal particles on engine parts back to the fuel tank and remove dirt generated on the working surfaces of the parts by the flow. lubricating oil.
