Abstract

The invention discloses an intelligent analyzer capable of rapidly and precisely analyzing diffusible hydrogen in metal. An electronic balance is connected with a main control panel arranged in a thermal conductivity detection assembly, a hydrogen signal transmitter is connected with an A / D collection and conversion unit arranged in the thermal conductivity detection assembly, the other end of the A / D collection and conversion unit is connected with the main control panel, and the other end of the main control panel is divided into two lines, wherein one line is connected with an infrared board arranged in an infrared extraction assembly, and the other line is connected with a sample injection control panel of a standard gas sample injection assembly. Compared with the prior art, a standard concentration curve is built with the standard gas sample injection assembly to calibrate the instrument, and a sample is rapidly heated at a constant temperature with the infrared heating extraction assembly to make the diffusible hydrogen rapidly escape. Infrared heating is adopted to sample extraction, and the sample is rapidly heated a constant temperature with the infrared heating extraction assembly to make the diffusible hydrogen rapidly escape. The analyzer has the advantages of simple structure, fast analysis speed and standard concentration curve, so that the precision of detection is provided.

Description

technical field [0001] The present invention is an intelligent rapid and high-precision analyzer for analyzing diffused hydrogen in metals, which relates to the technical field of analyzing diffused hydrogen in metals, and is mainly applicable to the determination of diffused hydrogen in metals and weld metals, and particularly relates to a rapid and high-precision analysis of metals Diffusion hydrogen analyzer. Background technique [0002] The diffusible hydrogen analyzer is mainly suitable for the analysis of diffusible hydrogen content in high-strength metals and weld metals in metallurgy, metal manufacturing, shipbuilding and other industries. The diffusible hydrogen analyzer of the analytical instrument uses infrared heating to extract the sample, and the thermal conductivity method measures the mass fraction of diffusible hydrogen in the sample. Diffusion hydrogen analysis The hydrogen in the sample is heated at a high temperature and constant temperature, and the hy...

AI Technical Summary

Problems solved by technology

Traditional diffusible hydrogen analyzers generally use glycerin method, mercury method and chromatography. These three methods collect diffusible hydrogen in metals at room temperature or 45°C in a closed container for 72 hours or even 10 days, and the operation time is long. Among them, the glycerin method , the viscosity of glycerin is high, and the escaped hydrogen is suspended in glycerin or adhered to the glass wall, which makes the test error large and the accuracy is not high
