Gas Permeation Experimental System

Gas Permeation Experimental System


(1) Mechanical loading functions; 1) Capable of real-time measurement of axial and radial (circumferential) stress and strain during the loading process of gas-containing coal rock cores under room temperature conditions, with computer output of stress-strain-time corresponding data and curves in real time; 2) Axial pressure and confining pressure can be applied at constant speed and constant flow, with the ability to switch between different loading speeds during the loading process. (2) Permeability testing functions; 1) Capable of measuring the steady-state permeability of gases (CH4, CO₂, N₂, He) in gas-containing coal rock cores under static and dynamic loads; 2) During the steady-state seepage process of gas-containing coal rock cores, capable of real-time measurement of adsorption expansion strain and desorption contraction strain.
