Laboratory gas storage tank pressure vessel defect quantitative analysis device

Abstract

The invention belongs to the technical field of pressure vessel safety analysis and discloses a laboratory gas storage tank pressure vessel defect quantitative analysis device. A metal magnetic memorydetection unit is used for detecting defects, including cracks, pits, slag inclusion, air holes and undercuts, of a pressure vessel in service to realize defect quantization; an A / D conversion unit is used for displaying numerical values detected by the metal magnetic memory detection unit on a nixie tube; a main control module is used for performing fracture analysis of plane defects on the pressure vessel in service; a fuzzy comprehensive analysis unit is used for making comprehensive safety analysis; and a GPRS transmission unit is used for sending field data to a monitoring terminal in atiming or real-time wireless remote transmission mode. By adopting the laboratory gas storage tank pressure vessel defect quantitative analysis device, a comprehensive analysis and judgment data tableis established, the total damage rate is calculated according to the damage rate of each failure factor to the pressure vessel and the weights of safety influence of each failure factor to the pressure vessel, and interrelation of various influences is clear so as to make comprehensive safety analysis; and an analysis result can more objectively and truly reflect the engineering practice.

Description

technical field [0001] The invention belongs to the technical field of pressure vessel safety analysis, and in particular relates to a quantitative analysis device for laboratory gas tank pressure vessel defects. Background technique [0002] The pressure vessel is a special pressure-bearing equipment with explosion hazard. It has the characteristics of high temperature, high pressure, flammability, explosion, and complicated process. Once an explosion or leakage occurs, the consequences will be extremely disastrous. Therefore, the safety and reliability of pressure vessels Analysis is even more important. Compared with other methods, magnetic memory testing is used to quantify defects, and then the comprehensive safety analysis of pressure vessels has distinctive features: first, as a new non-destructive testing method, magnetic memory testing is comprehensive and meticulous, and does not Affected by whether it is in operation or not, the operation is simple, the labor int...
