Vibration detection device for power plant pipeline

Abstract

The invention discloses a vibration detection device for a power plant pipeline. The vibration detection device comprises a fixed shell and a plurality of vibration transmission devices. The fixed shell is connected with the vibration transmission devices, and the vibration transmission devices are in contact with a measured pipeline and is fixedly arranged on the measured pipeline. When the pipeline vibrates, after vibration sensors in the vibration transmission devices receive a vibration signal, the vibration sensors convert the received vibration signal into an electric signal and transmitthe electric signal to a host connected with the vibration detection device for the power plant pipeline, and the host performs subsequent analysis processing on the vibration signal so as to ensurenormal use of the power plant pipeline. The vibration detection device can adjust the size, achieves the vibration detection of different pipe diameters of the steam-water pipeline of the power plant,effectively solves the problem that the high-temperature wall surface of the steam-water pipeline cannot be directly detected, and effectively transmits the vibration through the vibration transmission device, so as to achieve the vibration detection of the steam-water pipeline of the power plant.

Description

technical field [0001] The invention relates to a vibration detection device, in particular to a power plant pipeline vibration detection device, which belongs to the field of pipeline equipment detection. Background technique [0002] Pipeline vibration is a common phenomenon in the operation of power plants, and high-frequency vibration will cause great harm to pipelines. Including: Vibration accelerates the fatigue damage of pipeline materials, causing damage and failure of pipeline welding joints, causing failure of support and hangers, rupture of drain pipes, cracking of connection sockets and even pipeline blasting, damage to pipeline valves, and damage to measuring tubes and instruments on pipelines and other equipment. Therefore, in the operation and maintenance of power plants, the adjustment and vibration control of pipe supports and hangers has always been a regular and important task. The most important basis for the adjustment of the pipeline support and hange...
