The invention discloses a low-noise ship sea cooling water system, and belongs to the technical field of ship vibration and noise reduction, the low-noise ship sea cooling water system comprises a drainage mechanism, a cooling water pump, a heat exchanger, a drainage port and a conveying pipeline, the drainage mechanism is a tubular drainage structure extending out of the outer wall of a ship body and comprises a drainage port, and the drainage port is perpendicular to the ship body and faces the bow of the ship body; the heat exchanger comprises a first heat exchange mechanism and a second heat exchange mechanism, and the cooling water pump is arranged between the first heat exchange mechanism and the second heat exchange mechanism; the water outlet is formed in the ship body; the drainage mechanism, the cooling water pump, the heat exchanger and the water outlet are all arranged on the conveying pipeline. The invention provides a low-noise ship sea cooling water system which can remarkably improve the uniformity and stability of field flow in a pipe, so that noise elimination and flow stabilization can be achieved at the two ends of an inlet and an outlet of a cooling water pump, and then flow noise and noise transmission generated by the cooling water pump are restrained. And the noise level of the ship sea cooling water system is greatly reduced.
本发明公开了一种低噪声船舶通海冷却水系统,属于船舶减振降噪技术领域,包括引流机构、冷却水泵、热交换器、排水口和输送管道,引流机构为伸出船体外壁的管状引流结构,包括引流口,引流口垂直船体并朝向船体的船艏;热交换器包括第一热交换机构和第二热交换机构,冷却水泵设置在第一热交换机构和第二热交换机构之间;排水口设置在船体上;引流机构、冷却水泵、热交换器和排水口均设置在所述输送管道上。本发明提供了一种低噪声船舶通海冷却水系统,其能够显著改善管内场流的均匀性和稳定性,使得冷却水泵的入口和出口两端均能够得到消声和稳流,进而抑制了冷却水泵所产生的流噪声以及噪声传递,大幅降低船舶通海冷却水系统的噪声水平。
