Automatic coal adsorption constant testing device

  Product introduction of automatic coal adsorption constant test device the automatic coal adsorption constant test device is an intelligent equipment developed and manufactured by our company according to GBT 19560-2008 high pressure isothermal adsorption test method of coal
The instrument can measure the adsorption constant of coal to gas (a, b value), which is widely used in the rapid determination of gas content, calculation of mine gas pressure, analysis of coal adsorption characteristics and other experimental processes
It is an important index of mine gas basic parameters
The automatic coal adsorption constant test device automatically controls the gas adsorption experimental process, and the software fits the isothermal and high-pressure adsorption curve
It is a modern gas laboratory analysis instrument for mine production 。 Performance characteristics the fully automatic coal adsorption constant test device adopts the integrated design concept, integrates vacuum degassing, high-pressure inflation and high-pressure adsorption equipment, conforms to ergonomics, ensures the experimental operation, and the experimental process is programmed into the system control software to realize the fully automatic operation
The adsorption pressure is adjusted and controlled by imported solenoid valves and pressure sensors to reduce human error
The vacuum degassing and adsorption constant temperature system realizes automatic temperature rise and fall treatment, reduces the labor intensity in the process of artificial water temperature regulation, and speeds up the experimental process; In the high-pressure adsorption process, the plunger pump pressurization mode can be adopted according to the demand to realize the ultra-high pressure and most sites to fit the adsorption experimental process, so as to more objectively and accurately express the gas adsorption capacity; The program software has the functions of user-defined printing of experimental report, experimental chart, adsorption data storage, query and help
