(1) in the picture is an expansion joint, and the muffler is connected to the expansion joint. This part is used to discharge the high temperature and high pressure exhaust gas generated by the diesel engine into the atmosphere;< /p>
(2) in the picture is the air-cooled radiator of the diesel engine. If I read it correctly, this diesel generator should be the forced air cooled type. This type of diesel engine has a closed cooling water circulation system. When the diesel engine is running, the heat generated by the cylinder liner and other components as well as the lubricating oil system is cooled by the cooling water which absorbs the cooling water. the heat is cooled by the forced air cooling radiator. The cooled cooling water is then cooled by the cooling water to cool the machine, and so on. In normal operation, the temperatureThe temperature of the cooling water is stable between 75 and 85 degrees. If it exceeds 90 degrees, an alarm sounds. If it exceeds 95 degrees, it will stop, otherwise the diesel engine will be damaged.
How to solve high temperature fault of diesel generator. Briefly describe how to resolve the high temperature fault of the diesel generator.
Radiator. Air-cooled diesel generators typically use fans to draw outside air into the unit for cooling purposes to maintain the normal operating temperature of the generator. In front of the fan, a radiator and possibly a condenser are usually installed. These components are used to further cool the air entering the unit through the fan to ensure the normal operation and stable output of the generator.
1. Once the diesel generator starts working, when the temperature of the cooled liquidAfter reaching the thermostat opening temperature (80~90℃), touch the upper and lower water tanks of the radiator with your hands to check the temperature difference. It can be judged if the thermostat is open. A significant temperature difference indicates that the thermostat is not open.
2. Tip: To further check the thermostat, you can heat the thermostat in hot water and observe whether its opening temperature and maximum opening meet specifications. Although the diesel generator coolant temperature has reached the opening temperature of the thermostat, due to the paraffin leak in the thermostat, the valve opens too late, does not open sufficiently or cannot be open at all. The coolant cannot circulate widely. , and the diesel generator In this case, the work will overheat.
3. Cars equipped with expansion tanks will haveliquid level markings on expansion tanks. When refilling coolant normally, make sure the fluid level is between the highest and lowest fluid level marks. It should be noted that when the cooling system is drained and refilled with coolant, there will be air inside the system. Once the thermostat is opened, the air in the memory will be completely exhausted and the coolant level will drop. It is therefore essential to check the liquid level again after opening the thermostat.
