High-temperature pipeline vibration reduction device with guide bracket and vibration reduction method

Abstract

The invention belongs to the technical field of high-temperature pipeline vibration treatment, and particularly relates to a high-temperature pipeline vibration reduction device with a guide bracket and a vibration reduction method. The high-temperature pipeline vibration reduction device with the guide bracket comprises an upper pipe clamp, locking bolts, a lower pipe clamp, a guide base and a polytetrafluoroethylene pad, wherein the upper pipe clamp and the lower pipe clamp are both of semicircular structures; protruding bolt holes are formed in the two sides of the upper pipe clamp and the two sides of the lower pipe clamp respectively; the upper pipe clamp and the lower pipe clamp are connected through the locking bolts, and then the interior of the connected upper pipe clamp and lower pipe clamp is matched with a high-temperature process pipeline in shape; a guide rail matched with the guide base is welded to the bottom of the lower pipe clamp and embedded into the guide base; and the polytetrafluoroethylene pad is laid in the guide base. According to the high-temperature pipeline vibration reduction device with the guide bracket and the vibration reduction method provided by the invention, the high-temperature pipeline vibration reduction device has high feasibility and universality, can replace a damper to conduct vibration reduction on a high-temperature pipeline, and is short in implementation period and high in economic benefit.

Description

technical field [0001] The invention belongs to the technical field of high-temperature pipeline vibration control, and in particular relates to a high-temperature pipeline vibration damping device with a guide bracket and a vibration damping method. Background technique [0002] For the pipelines of the power station process system, due to the influence of many factors such as design defects, changes in working conditions, and unreasonable layout of supports and hangers, the pipelines will have high vibration problems. Among them, the vibration problem of high-temperature pipelines is the most sensitive. If relevant measures are not taken in time Vibration dampening measures can cause: [0003] (1) Long-term vibration of high-temperature pipelines produces fatigue fractures, which affects the safe and stable operation of nuclear power plant units; [0004] (2) If the high-temperature pipeline is damaged and cracked due to fatigue, the high-temperature medium will leak and ...
