Dynamic vibration absorber for industrial pipeline

Abstract

The invention provides a dynamic vibration absorber for an industrial pipeline. The dynamic vibration absorber comprises two brackets and two mass blocks. The two brackets can be symmetrically clamped on the outer wall of the pipeline, and can be butted and fixed. The two mass blocks are respectively and detachably mounted on the two brackets. When the pipeline vibrates, the dynamic vibration absorber for the industrial pipeline is driven to vibrate, and an inertia force generated due to the vibration of the dynamic vibration absorber for the industrial pipeline reacts on the pipeline, so as to achieve the effect of effectively inhibiting the vibration of the pipeline. When the dynamic vibration absorber for the industrial pipeline is mounted, proper mass blocks are selected according to the vibration characteristics of the pipeline, and through the adjustment of the weights of the mass blocks, the optimal vibration absorption effect of the pipeline is achieved, and the vibration absorption purpose of the pipeline is achieved.

Description

technical field [0001] The invention belongs to the field of vibration reduction of industrial pipelines, in particular to a dynamic vibration absorber for industrial pipelines. Background technique [0002] The reciprocating compressor unit will cause vibration of the piping system of the unit under working conditions, and there are certain differences in the vibration characteristics of different piping. Abnormal vibration of the pipeline system will seriously threaten safe production, such as: loosening of pipeline connection parts, fatigue damage of pipeline structure and its accessories, and serious pipeline rupture and leakage; pipeline vibration can cause Vibration occurs, impairing the normal function of the meter. [0003] In recent years, there have been frequent abnormal downtime events caused by the vibration of the pipeline system. In 2012, the oil-filled seamless steel pipe of a certain unit broke under high-frequency and small-scale vibration, and was forced...

AI Technical Summary

Problems solved by technology

In 2012, the oil-filled seamless steel pipe of a certain unit broke under high-frequency and small-scale vibration, and was forced to shut down for maintenance; in the same year, the pipeline of a reciprocating compressor unit in a gas storage was severely indented due to large vibrations throughout the year; in 2013 , the tertiary outlet pipeline of a compressor in a gas storage store was broken due to the large vibration all the year round, and the elbow of the connecting branch pipe was broken, and the site was shut down unplanned for one month

The steel wire rope is the main vibration-absorbing element, and its structural characteristics determine the shortcoming of the vibration-absorbing frequency of the vibration absorber being relatively narrow.

When the vibration absorber faces the radial vibration of the pipeline, the additional mass ring will shake with the pipeline, hit the pipeline, and cause huge wear of the steel wire rope

When the vibration absorber is not working, the additional mass ring will also exert greater pressure on the wire rope, which will accelerate the fatigue of the wire rope and have a greater impact on the vibration absorption effect
