Technical Field

The utility model relates to an industry pipeline safety monitoring technique, especially a pipeline bracket for LDPE, EVA device, specifically speaking are a damping support that is used for high pressure, superhigh pressure pipeline with vibration monitoring function.

Background

LDPE & EVA (low density polyethylene & ethylene-vinyl acetate copolymer) is generally produced by high pressure method, the pressure of medium in the pipe at the rear end of the compressor in the device can reach 50-400MPa (so the pipe used is generally called high pressure or super high pressure pipe), and the pulsation generated by the compressor and other power equipment can cause the vibration of the high pressure pipe. For this reason, a high-pressure vibration damping bracket is generally used as a bracket for supporting a high-pressure or ultrahigh-pressure pipeline.

For high-pressure and ultrahigh-pressure pipelines, how to control the vibration of the pipelines is extremely important for the stable and safe operation of the pipelines, otherwise, the control effect can cause great harm to the long-term operation of the pipelines, including: the vibration accelerates the fatigue damage of the pipeline material, causes the looseness of the flange interface between the pipeline and the connecting pipe orifice of equipment such as a compressor and the like, damages a pipeline valve, damages equipment such as a measuring gauge pipe and an instrument on the pipeline, and even causes serious accidents such as high-pressure and ultrahigh-pressure medium leakage and the like. Therefore, in the operation and maintenance of high-pressure and ultrahigh-pressure pipelines of such devices, the health monitoring and management of the vibration of the pipelines is always a frequent and important task.

Because of the high pressure and ultra high pressure properties of the pipeline in the production device, it is necessary to become a high-level hazard source, and the peripheral HSE management level also belongs to a high-level rank. Most of the existing pipeline monitoring and detecting instruments or devices are focused on portable or manual real-time detection, and the measuring method and the evaluating method are not suitable for the working condition requirements of high-pressure and ultrahigh-pressure pipelines, so that a vibration monitoring device suitable for the high-pressure and ultrahigh-pressure pipelines is urgently needed for monitoring the vibration condition of the pipelines and the vibration damping effect of a high-pressure vibration damping support; the high-pressure and ultrahigh-pressure pipelines are not provided with vibration monitoring devices, and the special working conditions of the high-pressure and ultrahigh-pressure pipelines ensure that external vibration sensors and the like cannot root and fix on the body for a long time by methods such as punching. Therefore, the high-pressure vibration reduction support with the vibration monitoring function for the high-pressure pipeline and the ultrahigh-pressure pipeline is developed by combining the requirements.
