Abstract

The invention discloses a pipeline vibration test platform based on fault diagnosis and automatic processing, and a control method thereof. The pipeline vibration test platform comprises a pressure tank, a pipeline, a substrate and a signal analysis processing system. The pressure tank is arranged on the substrate and controls and adjusts the flow speed and pressure of a water flow in a pipeline. A plurality of supports sleeve the pipeline. The pipeline is arranged on the substrate through the supports. The substrate is provided with a track, and the support can move along the track. The signal analysis processing system comprises an acceleration sensor and a micro-processor. The acceleration sensor is connected with the micro-processor through a data collection card. The acceleration sensor is arranged on the pipeline. The micro-processor controls a motor to drive the supports to move along the track and controls the on-off degree of a valve. The analysis of pipeline abnormal vibration due to a plurality of factors is realized, the pipeline vibration is automatically adjusted, the method for reducing the pipeline abnormal vibration is explored, and various kinds of emergency processing means are assessed and optimized.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis and automatic processing, in particular to a pipeline vibration test platform and control method based on fault diagnosis and automatic processing. Background technique [0002] Pipeline is an indispensable element in fluid transmission, transmission and control engineering to transport fluid medium, transmit fluid power and fluid information, and is widely used in various industrial fields. In the actual pipeline system, due to periodic changes in the working state of the system or external interference, it will inevitably generate flow and pressure shocks or pulsations in the pipeline, which will excite the mechanical vibration and noise of the fluid pipeline, and cause the connection parts of the pipeline to occur. Loose or broken, it may cause leakage, pollute the environment, damage components, or cause major equipment damage and casualties. [0003] There are many factors for pipeli...
