Because the specific heat capacity of water is large, it shows that the temperature of water needs more heat, and it also has the characteristics of low boiling point, so it has certain influence on the cooling of the machine and can reduce the temperature of the machine in a short time. As we all know, this kind of ship usually chooses a high-power engine because of its large size and long running time. Working like a human being for a long time will make you tired. If the engine is used for a long time, it will also produce high temperature and heat. If the engine temperature is high, the piston inside will expand, causing the cylinder to get stuck. The longer the time, the greater the possibility of explosion.
In the event of an explosion, ships and cargo are very dangerous, and may even cause casualties, which is very terrible. In order to solve this problem, engineers designed a system to cool the engine. There are internal and external systems. Because seawater and fresh water are different, they are resistant to seawater corrosion and impurities, so there is a risk of direct contact with engine parts. Therefore, the internal cooling system does not use seawater, but water and oil to keep the temperature in the engine within the normal range.
The external cooling system adopts seawater, and the rotating heat exchanger cools the hot water circulating inside. The valve at the bottom of the ship automatically sucks seawater and then sends it to the equipment in the ship to use seawater. Finally, it is sent to one side of the ship through the pipeline, which is the two sides of the ship that we often see. In addition, a small part of the sprayed water is domestic sewage from the ship. Is it strange to see my friend here?
