Working principle:
When the diesel generator is working, it will generate a lot of heat. Cooling water is needed to cool the diesel engine. The cooling water takes away the heat of the diesel engine. At the same time, the high-temperature cooling water from the diesel engine also needs a cooling water medium to cool it. There are two commonly used methods: one is that the fan driven by the diesel engine cools the high-temperature cooling water in the water tank, commonly known as air cooling: the other is to cool the cooling water inside the diesel engine through the water in the pool or cooling tower, commonly known as water cooling.
Air cooling and water cooling have their own advantages. We can make choices according to their use environment. Generally, the unit needs to be moved frequently. Air cooling should be selected. If the unit is fixed for a long time, water cooling should be selected. Water cooling is selected, because the fan and cooling water tower are removed, which can reduce the noise of the unit by about 10 decibels. At the same time, the power consumed by the fan is about 5% of the rated power of the unit. Generally, in hot weather areas, the water temperature of the diesel engine often exceeds the rated range, thus causing the diesel engine to run at high temperature, while the cooling water tower can be considered to control the water temperature and air cooling is limited.
The cooling principle is as follows:
The hot water generated when the diesel engine is working flows from the water outlet pipe of the diesel engine to the heat exchanger. The cold water in the cooling pipe of the heat exchanger cools the circulating hot water of the diesel engine. The circulating hot water of the diesel engine is cooled and returned to the diesel engine. The diesel engine is cooled. The cold water in the cooling pipe of the heat exchanger rises in water temperature after cooling the circulating hot water of the diesel engine, is pumped to the cooling tower for cooling, and is sent to the cooling pipe of the heat exchanger after cooling. The water temperature of the diesel engine can be adjusted by adjusting the opening of the water valve, and the filter screen filters the cold from the cooling tower before entering the heat exchange tube. The water cooling project can ensure that the diesel engine works at the best water temperature of 85-90 degrees Celsius.
