Differentdiesel generatorsmanufacturers and different power diesel generators use different oils. Normally, a new engine operates 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 filter (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 pparts to prevent water, air, acidic substances and harmful gases from coming into contact with 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. An oil film 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.
What type of diesel is generally used for diesel generators?
Shantou Ka generators need both, and the commonly used ones are 92 and 95 gasoline .
It seems inferiorto the old standard but more reasonable, as the compression ratio range of engines is increasingly wider, including multi-point EFI engines with less than 10:1 and mid-level direct injection. engines But there are also high-performance machines with significantly improved compression ratios. 97# is a bit redundant for mid-level engines, but not suitable for high-level engines, so there are two options, 95 and 98.
The basis for choosing diesel is temperature during use. Diesel vehicles mainly use the last five brands of diesel. When the temperature is above 4℃, choose 0# diesel when the temperature is between 4℃ and minus 5℃, choose -10# diesel when the temperature is between minus 5℃; and minus 14℃, choose -20# #Diesel;
When the temperature is between minus 14℃ and minus 29℃, choose -35# diesel if the diesel grade thatyou choose is higher than the one above. temperature, the engine's fuel system can build up wax and block the oil system. Affect normal engine operation.
Detailed information
Principle of diesel generator
In short, the diesel generator operates the generator. In the cylinder, the clean air filtered by the air filter is fully mixed with the high pressure atomized diesel fuel injected by the injector. Under the upward pressure of the piston, the volume decreases and the temperature increases rapidly, reaching the ignition point of. diesel fuel. The diesel ignites, the gas mixture burns violently, and the volumeRapid expansion pushes the piston down, which is called work.
Each cylinder does work in a certain order, and the thrust acting on the piston becomes the force that causes the crankshaft to rotate through the connecting rod, thus driving therotation of the crankshaft. By installing the brushless synchronous alternator coaxially to the crankshaft of the diesel generator, the rotation of the diesel generator can be used to drive the generator rotor. Using the principle of "electromagnetic induction", the generator will produce induced electromotive force. a closed load circuit can produce current.
