(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;
(2) in the picture is the air-cooled radiator of the diesel engine. If I read it correctly, this diesel generator set should be a forced air cooling type. This kind 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. The cooling water that absorbs the heat is cooled by the forced air cooling radiator. The cooled cooling water is then cooled by the cooling water. To cool down the machine, and so on. Under normal operation, the temperature of the cooling water is stable between 75 and 85 degrees. If it exceeds 90 degrees, an alarm will sound. If it exceeds 95 degrees, it will shut down, otherwise the diesel engine will be damaged.
Hello, I work in refrigeration, I hope it can be helpful to you
The working principles of air cooling and water cooling are the same. Both have compressors to compress the refrigerant (usually Freon). ) is intercepted by the condenser cooling expansion valve, evaporates and absorbs heat in the evaporator, and then returns to the compressor to form a cycle. The difference between air cooling and water cooling mainly lies in the condenser. Water cooling uses cooling water (usually a cooling tower) to absorb the heat of high-pressure refrigerant. Air cooling is accomplished by using a fan to circulate the air
Water cooling is better than air cooling. The disadvantage is that it requires a cooling tower. Air cooling is suitable for places where it is inconvenient to connect to a cooling tower, but the ventilation is better.
