High-pressure pipeline and vibration attenuation device thereof

Abstract

The invention provides a high-pressure pipeline and a vibration attenuation device thereof. The vibration attenuation device comprises a concave flange, a convex flange, a bolt, a nut and a spring; wherein the concave flange and the convex flange are fixed through the bolt and the nut, the spring is arranged between the convex flange and the concave flange, and the bolt passes through the spring. The high-pressure pipeline is provided with the vibration attenuation device, according to the vibration attenuation device, the pipeline is allowed to vibrate to produce a shift so as to release the vibration of the pipeline, after the vibration, the pipeline can be enabled to freely restore into an initial state by the spring inside the vibration attenuation device, and meanwhile the vibration is isolated. By the adoption of the vibration attenuation device, the problem of vibration of the high-pressure pipeline can be improved, the operation quality of equipment is improved, and the vibration attenuation device has extremely high application value.

Description

technical field [0001] The invention relates to vibration reduction technology, in particular to a vibration reduction device for high-pressure pipelines. Background technique [0002] The current high-pressure hydraulic pipelines, especially the hydraulic pipelines of large-scale hydraulic machines, such as extrusion machines, forging presses, etc., have high pressure and sudden changes in pressure will cause more mechanical vibrations. If the vibration caused cannot be eliminated, it will be transmitted from the vibration source to other parts of the equipment, resulting in large vibration and noise during the operation of the equipment. Long-term periodic vibration will cause great harm to the operation of the equipment. If possible Loosening of nuts or screws of fasteners, damage of seals at pipes or flanges, etc., will affect the normal operation of the equipment, and even cause fire and personal injury. Contents of the invention [0003] In view of the above-mention...
