Performance test system and test method for explosion suppression and explosion resistance mining device

Abstract

The invention discloses a performance test system and test method for an explosion suppression and explosion resistance mining device. The performance test system is characterized by comprising a test steel pipe (6) capable of being pumped to negative pressure, and a detection and ignition unit and a test and gas supply unit (13) are arranged on the pipe wall of the test steel pipe (6); an explosion suppression and explosion resistance device is fixed at the middle part of the test steel pipe (6); a sensor group (5) used for triggering the explosion suppression and explosion resistance device is mounted in a pipeline between the detection and ignition unit and the explosion suppression and explosion resistance device, and a plurality of flame sensors (14) are mounted on the pipe wall between the test and gas supply unit (13) and the explosion suppression and explosion resistance device; a controller which is connected with the detection and ignition unit, the test and gas supply unit (13), the sensor group (5) and the flame sensors (14) and controls the components to work is arranged. The performance test system can simulate the real negative-pressure environment in an extraction pipeline, so that the test concentration is arbitrarily set, and the performance test system is strong in universality.

Description

technical field [0001] The invention discloses a performance test system and a test method of a mine anti-explosion and anti-explosion device, which belong to the technical field of mine safety equipment testing. Background technique [0002] Explosion suppression and explosion prevention devices are common safety equipment in mines. Once a fire occurs in the extraction pipeline, the explosion suppression and explosion prevention device can respond quickly to prevent the flame from spreading in the extraction pipeline to avoid further damage. for serious safety accidents. In view of the important role of explosion suppression and explosion arresting devices, in the event of a fire, whether the actual performance of explosion suppression and explosion arresting devices can achieve the expected effect is a key issue of concern to people, so it is necessary to use reliable testing equipment Explosion, explosion-proof device performance test. [0003] In the existing test devi...

AI Technical Summary

Problems solved by technology

[0003] In the existing test devices, there are generally the following defects: (1) the existing test devices cannot simulate the negative pressure environment in the drainage pipeline, so the most accurate test results cannot be obtained; (2) in the test device The methane concentration cannot be set arbitrarily, and the adaptability is poor; (3) Only one or a type of product can be tested, and the versatility is poor
