The invention provides a buried pipeline implosion coupling interface parameter experiment testing device. The buried pipeline implosion coupling interface parameter experiment testing device comprises a liquid storage tank, a check valve, a metal liquid inlet pipe, a centrifugal pump, a flow meter, a fiber hose, a pipeline reducer union, an experiment pipeline and a pressure gauge which are connected in sequence. The device comprises a JM5930 dynamic signal testing system connected with a dynamic displacement sensor, a dynamic strain sensor, a dynamic pressure sensor and a dynamic acceleration sensor, and the sensors are arranged on an experimental pipeline; the device comprises a pipeline combination support and a protective cover which are placed on a fixed support, and the protective cover protects the pipeline combination support. An experiment pipeline is rigidly fixed on the pipeline combination bracket; the device comprises a TNT igniter connected with an experimental pipeline.According to the scheme, TNT is used as an explosion source, and the real explosion effect is completely simulated; pressure, displacement, stress and acceleration transmission of the fluid propertyand the flowing state in the pipe and a pipeline structure and soil body coupling interface are fully considered.
Description
technical field [0001] The invention relates to the technical field of buried pipeline safety testing, in particular to an experimental testing device for buried pipeline external explosion coupling interface parameters. Background technique [0002] With the rapid development of the petroleum and petrochemical industry, among various oil and gas transportation methods, the advantages of pipeline transportation are gradually revealed. Pipeline transportation has obvious economics. It is directly driven by oil pumps and compressors, and oil and gas flow around the clock. It is easy to realize automatic operation and requires fewer operators. And it occupies less land, and the construction is fast. In recent decades, the global oil and gas pipeline construction has entered a peak period. Under such circumstances, the safety production of long-distance buried oil and gas pipelines has been paid more and more attention. Due to accidental external explosion loads such as leakag...
