Abstract

The invention discloses a system and a method for testing a local resistance loss coefficient of a flame arrester. The invention belongs to the technical field of flame spreading blocking in the petrochemical industry, and particularly relates to a monitoring and testing device for realizing changes of pressure, temperature and flow of experimental gas in pipelines at the front end and the rear end of a flame arrester and a calculation method of a local resistance loss coefficient comprehensively considering the pressure, the temperature and the flow in a flowing process of compressible gas ina test pipeline. The device comprises a mechanical structure unit and an electric control data acquisition unit, can correctly measure local resistance loss data caused by the flame arrester, and ishelpful for improving the reliability of the flame arrester in the using process and perfecting a corresponding theoretical system and technical specifications in flame arrester testing to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of blocking flame spread in the petrochemical industry, and in particular relates to a test system and method for the local resistance loss coefficient of a flame arrester. Background technique [0002] Flame arresters can be used to prevent flammable and explosive gas or liquid vapor flames from spreading in industrial equipment pipelines, and play an important role in petrochemical, natural gas and other enterprises. In order to ensure the flame-retardant and explosion-proof performance of the flame arrester and ensure safe production, it is particularly important to correctly measure the specification parameters of the flame arrester, especially the local resistance loss data caused by the flame arrester. However, there is still a large gap in the professional experimental equipment and testing system for flame arrester performance testing in China. The relatively complete theoretical system, technical sp...
