Problems solved by technology

[0002] At present, the fluid turbulence caused by the complex structure of the circulating water system will cause bubbles to form at the suction port of the circulating water system, and together with the seawater sucked by the circulating water system, enter the circulating water pipeline of the circulating water system in the form of two-phase flow. When the vibration frequency of the pipeline caused by the fluid excitation in the water pipeline is close to or consistent with the natural frequency of the circulating water pipeline or the vibration frequency of the pipeline excited by the external power machinery of the circulating water pipeline, it will cause the circulating water pipeline of the circulating water system to resonate and reduce Quietness of circulating water system
[0003] The traditional way to avoid resonance in the circulating water pipeline of the circulating water system is to use a pipeline vibration isolator, but the pipeline vibration isolator is suitable for isolating medium and high frequency vibrations, and the pipe vibration caused by the fluid excitation

Abstract

The embodiment of the invention provides a system and method for reducing the influence of fluid excitation vibration in a circulating water pipeline. The system comprises a gas source, a gas guidingpipe and a flow control valve. The flow control valve is arranged on the gas guiding pipe. One end of the gas guiding pipe communicates with the circulating water pipeline through the side wall of thecirculating water pipeline, and the other end of the gas guiding pipe is connected with the gas source. The gas source is used for supplying gas into the circulating water pipeline. According to thesystem and method for reducing the influence of the fluid excitation vibration in the circulating water pipeline provided by the embodiment of the invention, the gas is introduced into the circulatingwater pipeline to enable the peak frequency of the fluid pulsating pressure of a two-phase flow in the circulating water pipeline with the introduced gas to be out of a preset range, preventing resonance of the circulating water pipeline caused by the fluid pulsating pressure; therefore, the quietness of the circulating water pipeline is improved, and the stability of the entire circulating watersystem and the environmental quietness are ensured.
