Device and method for testing fire protection ability of pipeline

Abstract

The invention provides a device for testing the fire protection ability of a pipeline. The device comprises a combustor, a sensor and a data collection system, wherein the combustor is used for combusting the pipeline, and an ignition region is formed by a flame region of the combustor; the sensor is used for sensing at least one physical parameter of the pipeline and/or the other pipeline in an/or out of the ignition region and outputting a sensing result; and the data collection system is stored with a material property storage coefficient of the pipeline and a pre-warning value determined according to the relation between the coefficient and the physical parameter and is used for calculating the physical parameter of the pipeline according to a sensing result, carrying out comparison onthe physical parameter of the pipeline and a pre-warning value and emitting a warning signal when the physical parameter of the pipeline exceeds the pre-warning value. The invention further providesa method for testing the fire protection ability of the pipeline corresponding to the device.

Description

technical field [0001] The invention mainly relates to a pipeline fire prevention capability test, in particular to a high-accuracy, high-safety pipeline fire prevention capability test device and method. Background technique [0002] The fire resistance rating refers to the ability of components to maintain their original functions when exposed to a heat field or other specific environment and withstand a flame temperature of 1000-1200 ° C for about 5 minutes or 15 minutes. [0003] In the field of aero engines, the external pipelines of the engine used to transmit flammable liquids such as fuel oil and lubricating oil are located in areas where the engine may catch fire. Therefore, ensuring the fire protection of the external pipeline of the engine is an important part of the engine safety design, and verifying the fire prevention capability of the external pipeline of the engine is an important indicator. The pipeline fire test method stipulated in the existing aviation ...

AI Technical Summary

Problems solved by technology

The pipeline fire test method stipulated in the existing aviation industry standard HB7044-94 "Fire Test of Hose and Hard Pipe Components" only specifies the burner equipment and test environment, and does not specify the test items and tests. The method is clearly stipulated, and the test result can only be judged by visually observing whether there is a crack or leakage / leakage during the test. If there is a crack or leakage / leakage, the test fails

Such a test verification method is highly subjective and lacks data support, and the test results must be observed after the pipeline ruptures or leaks / leakage occurs
