Abstract

The embodiment of the invention provides a system and a method for reducing the influence of fluid excitation vibration on a ship seawater system. By introducing long-chain polymers into a seawater pump discharge pipe and ensuring the peak frequency of the fluid fluctuating pressure in the seawater pump discharge pipe introduced with the long chain polymers to be outside a preset range, the systemand the method for reducing the influence of the fluid excitation vibration on the ship seawater system have the advantages of preventing the fluid fluctuating pressure from causing the resonance ofthe seawater pump discharge pipe, further weakening the influence of the fluid excitation vibration in the seawater pump discharge pipe on the seawater pump discharge pipe, improving the quietness ofthe seawater pump discharge pipe, and guaranteeing the stability of an entire ship seawater system and the quietness of the environment.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of safety control of marine seawater systems, and more specifically, to a system and method for reducing the impact of fluid excitation vibration in marine seawater systems. Background technique [0002] At present, the pipelines of the marine seawater system are complex and there are many disturbance sources. The fluid disturbance caused by the complex structure of the marine seawater system will cause air bubbles in the pipeline of the marine seawater system of the vessel, and together with the seawater in the pipeline of the marine seawater system of the vessel, it will form a two-phase flow. The form flows in the ship's seawater system. There are multiple seawater user equipment downstream of the seawater pump discharge pipe. When the pipeline vibration frequency caused by the fluid excitation in the seawater pump discharge pipe is close to or consistent with the structural natu...
