Pipeline vibration reduction grillwork based on metal rubber and working method of pipeline vibration reduction grillwork

Abstract

The invention relates to the technical field of pipeline vibration reduction, in particular to a pipeline vibration reduction grillwork based on metal rubber and a working method thereof.The pipeline vibration reduction grillwork comprises a square grillwork body, a plurality of octagonal through holes arranged in order in an array mode are formed in the square grillwork body, and elastic sheets are arranged on rectangular planes of the faces, spaced in pairs, of the octagonal through holes; the elastic sheets are in a protruding shape, one ends of the elastic sheets are connected with the square grillwork, the other ends of the elastic sheets are free ends capable of freely stretching out and drawing back when the elastic sheets are pressed by vibration, and metal rubber making contact with the lower surfaces of the elastic sheets is installed on the rectangular plane where the elastic sheets are located in the octagonal through holes. The pipeline vibration reduction grillwork based on the metal rubber can effectively reduce flow-induced vibration of pipelines, avoid fretting contact abrasion between the pipelines and prolong the service life of a pipeline system.

Description

technical field [0001] The invention relates to the technical field of pipeline vibration reduction, in particular to a metal rubber-based pipeline vibration reduction grid and a working method thereof. Background technique [0002] Piping system is one of the important engineering structures widely used in modern industrial devices. Among them, hoses are widely used in short-distance transmission, transmission at elbows, transmission of various media, etc. due to their high transmission efficiency, simple structure and strong flexibility. , and often in practical engineering applications, there will be dozens or even dozens of hoses to form a pipeline system for transmitting media. [0003] The industrial environment often has harsh conditions such as high temperature, high pressure and noise, which will affect the pipeline transmission system. The flow-induced vibrations cause contact wear between the hoses, and in severe cases, the hoses will wear through, resulting in m...

AI Technical Summary

Problems solved by technology

[0003]The industrial environment often has harsh conditions such as high temperature, high pressure, and noise, which will have an impact on the pipeline transmission system, and the pipeline system composed of several hoses has the greatest impact What is most important is that due to the flow impact of the transmission medium, the overall and local flow-induced vibration of the hose will cause contact wear between the hoses, and in severe cases, the hose will be worn through and the medium will leak

At present, the existing grids are often simply used to separate the pipes and avoid confusion, but have no effect on reducing the vibration of the pipelines and avoiding wear and tear. Sliding abrasion and fretting contact wear occur, which accelerates the wear of the pipeline and reduces the life of the pipeline
