Abstract

The invention relates to the technical field of ship cooling systems, and discloses a self-flowing cooling system and a control method thereof. The device comprises a self-flowing generator which is mounted at a bottom housing of a ship body in a lifting manner, and a water inlet channel which is arranged in the self-flowing generator, wherein the lower end part of the self-flowing generator externally extends out of the bottom housing of the ship body; the front side of the lower end part of the self-flowing generator is an incident flow surface; and a water inlet of the water inlet flowing channel is formed in the incident flow surface. According to the system, the height of the self-flowing generator extending out of the bottom housing of the ship body is adjustable; the system can control and adjust the extending height of the self-flowing generator in real time according to the actual requirement of the flow rate of cooling seawater; the active adjustment matching supply of the self-flowing cooling seawater is realized; the problems of vibration of an adjusting device and large system noise in a passive throttling mode are solved; and the dragging resistance of the self-flowing generator to the ship body can be effectively reduced in the state that the self-flowing generator does not extend out completely.

Description

technical field [0001] The invention relates to the technical field of ship cooling systems, in particular to an artesian cooling system and a control method thereof. Background technique [0002] The cooling system is an important part of the ship's power system, and it is an important link that must be paid attention to to further improve the ship's performance. In order to alleviate the problem of scaling and corrosion, the current advanced ships adopt the central cooling water system. Its working principle is to use the sea water pump to transport seawater into the central cooling system to cool the low-temperature fresh water. The cooled low-temperature fresh water is then used to cool the main diesel engine of the ship. High-temperature fresh water in cylinder liners, cylinder heads, various coolers and cylinder liners of power generation diesel engines and other parts that need to be cooled. [0003] The existing central cooling system of ships requires the use of se...
