Description

Pipeline vibration damper
Technical Field
The disclosure relates to the technical field of natural gas pipeline transportation, in particular to a pipeline vibration damper.
Background
At present, a plurality of compressors are usually arranged along a natural gas conveying pipeline to pressurize natural gas in the pipeline and improve the conveying capacity of the natural gas pipeline. When the compressor works, the cylinder of the compressor intermittently inhales or exhausts gas, and the gas column of the pipeline is excited to vibrate, so that the pressure and the speed of the natural gas fluid are periodically changed, and airflow pulsation is formed. When the airflow pulsation meets a bent pipe, a reducing pipe, a valve or a blind plate, impact is generated on the pipeline, and the pipeline is vibrated. And strong pipeline vibration can lead the working condition of the air valve to be deteriorated, the instrument fails and the connecting part of the pipeline accessory to be loosened. Continuous pipe vibration can also cause fatigue failure of the entire pipe system, resulting in natural gas leakage, and in severe cases, can cause the pipe to break, causing pollution or explosion, resulting in serious accidents.
Therefore, it is necessary to damp the vibration of the pipe using the pipe damping device. The pipeline vibration damper in the related art generally includes a support frame, a pipeline bracket and an arc-shaped pressing plate, wherein the pipeline bracket is fixedly disposed on the support frame, the arc-shaped pressing plate is disposed on the pipeline bracket, a circular holding groove having a shape matched with that of the pipeline is formed between the pipeline bracket and the arc-shaped pressing plate, the pipeline is disposed in the holding groove, and the pipeline is clamped between the pipeline bracket and the arc-shaped pressing plate. The pipeline bracket and the arc-shaped pressure plate are locked and fixed through connecting bolts, and the connecting bolts are arranged along the vertical direction.
However, the above-described pipe bracket and the arc-shaped pressing plate clamp the pipe from the vertical direction. When the pipeline vibrates along the horizontal direction, horizontal acting force can be generated to act on the pipeline bracket and the arc-shaped pressing plate. Because the pipeline bracket is fixed and can't remove on the support frame, and the arc clamp plate activity sets up, consequently, under the effect of horizontal direction's effort, can produce relative movement between pipeline bracket and the arc clamp plate, form the shearing force. The shearing force acts on the connecting bolt, the connecting bolt is easy to damage, and therefore the clamping effect of the pipeline bracket and the arc-shaped pressing plate on the pipeline is failed, and the vibration reduction effect cannot be achieved.
