Water cooling system is widely used, but do you know its composition and working process?
July 08, 2022
Water cooling system, as the name implies, is to use water as a medium to cool the heated parts of the diesel generator set, and then transfer the heat to the air, a cooling method, the advantage of this cooling method is that the cooling is more uniform, cooling intensity is easy to adjust, can make the diesel generator set in the most suitable temperature range, at the same time, even in the cold winter or long years of cold areas, you can use the method of filling hot water or preheat the diesel generator with auxiliary electric heating, so it is easy to start, so it is widely used.

1, open cycle cooling system. Open circulation cooling system, that is, the inlet and outlet of the diesel engine is open, when using by the user to connect the water. According to the different arrangement of diesel engine models and oil coolers, the form of open circulating cooling system is also slightly different. The coolant flow direction is shown in the figure below.
Therefore, appropriate measures should be taken to adjust the appropriate inlet water temperature for the open circulating cooling system. Generally can be installed between the water source and the diesel generator a mixing bucket (pool), the diesel generator water inlet and outlet and the water from the water source to the mixing bucket, by controlling the amount of cold water into the mixing bucket, you can control the inlet water temperature of the diesel generator.
2, closed-cycle cooling system. The so-called closed-cycle cooling system, is the diesel generator cooling system itself into a complete closed loop, land-based diesel engine closed-cycle cooling system that is the high-temperature coolant from the diesel engine, through the water radiator by the fan strong blast to cool, cool the water to cool the diesel engine: closed-cycle cooling system, according to the model and the use of different oil cooler and different.
