Introduction to the Intelligent Gas Permeability Coefficient Tester
The Intelligent Gas Permeability Coefficient Tester is an automated product independently developed by Zhengzhou Aidi Technology Co., Ltd. It is primarily used to measure the permeability coefficient of gas in coal and rock. This indicator directly reflects the difficulty of gas extraction in mines, providing scientific data for reasonably arranging pre-extraction time and calculating extraction radius, thereby improving gas extraction efficiency. It is suitable for gas laboratories in coal mines, testing and research institutions at all levels, and universities for testing, research, and teaching purposes.
Compliance Standards
MT223.4-90 "Method for Determining the Permeability Coefficient of Coal and Rock"
Performance Features
Confining pressure is controlled using variable frequency control technology, automatically pressurized according to the pressure set by the computer.
Data acquisition and control are managed through a highly reliable computer, storing data charts. Equipped with a printer interface, it can print experimental reports and charts.
Axial loading, confining pressure, and seepage pressure functions for coal samples are achieved, with pressure ranges meeting specified requirements.
Capable of preparing test specimens for coal (or rock) pillars under natural moisture, dry, and water-saturated conditions simultaneously.
The device features an integrated design, is sturdy and durable, and is simple and convenient to operate.
Seepage pressure is adjusted using regulating valves to meet pressure and flow requirements.
The experimental process is intelligent and fully automated. After sample preparation, the experimental procedure is completed with a single click, automatically calculating data results.
