Bent pipe vibration and noise reduction system and vibration and noise reduction control method

Abstract

The invention provides a bent pipe vibration and noise reduction system and a vibration and noise reduction control method, and relates to the technical field of ship pipeline vibration and noise reduction, the bent pipe vibration and noise reduction system comprises a vibration reduction assembly, the vibration reduction assembly comprises a plurality of impellers arranged at intervals, the impellers are installed on a sliding rod, and a distance adjusting device is used for adjusting the distance between every two adjacent impellers in the vibration reduction assembly; the vibration sensor is positioned in the bent pipe and is used for detecting a vibration intensity value; and the controller is used for controlling the distance adjusting device to adjust the distance between the two adjacent impellers according to the vibration intensity value. Liquid flowing through the bent pipe is buffered through the multiple impellers arranged at intervals, the buffering degree is adjusted by adjusting the distance between the adjacent impellers, the distance between the adjacent impellers is adjusted according to the vibration intensity value, the vibration reduction assembly rapidly achieves the state of conducting vibration reduction on the fluid, and the situation that the bent pipe generates large noise during working is prevented.

Description

technical field [0001] The invention relates to the technical field of vibration reduction and noise reduction for ship pipelines, in particular to a vibration reduction and noise reduction system for bent pipes and a control method for vibration reduction and noise reduction. Background technique [0002] In the pipeline of the ship power system, there is usually a flowing fluid. When passing through a curved pipeline structure such as an L-shaped or U-shaped pipeline, severe turbulent flow will be formed in and near the curved section of the pipeline, resulting in Rotation, arouse the vibration of the pipeline and generate strong flow-induced noise. [0003] At present, in the continuous upgrading of the ship system, other noises are effectively slowed down. The flow noise caused by the pipeline in the ship has gradually become an important noise source in the power cabin, which affects the body and mind of the ship staff and seriously affects the concealment of the ship. ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an elbow vibration and noise reduction system and a vibration and noise reduction control method, which are used to solve the severe turbulent flow of the ship elbow in the prior art due to the fluid flow, which causes the rotation in the bending section and arouses the pipeline turbulence. Vibrates and produces strong flow-induced noise, which not only affects the body and mind of the ship's staff, but also seriously affects the concealment of the ship. A bending pipe vibration and noise reduction system and a vibration and noise reduction control method are realized.
