WT-1 gas diffusion velocity teste

  WT-1 gas diffusion velocity tester product introduction WT-1 gas diffusion velocity tester is an alternative model of the old gas diffusion velocity tester
The new function is more intelligent
WT-1 gas diffusion velocity tester adopts American sensor to realize computer monitoring and control
The whole test process can be completed by pressing the corresponding key according to the prompt of the computer interface; The error caused by human factors on the experimental results is eliminated; The test results are automatically stored and printed out in the form of curve report
WT-1 gas diffusion velocity measuring instrument is mainly used to measure the coal quality index - initial gas emission velocity △ P in the risk prediction of coal and gas outburst; Examine and study the gas emission characteristics of coal, and continuously measure the gas diffusion rate △ D in 0 ~ 60s after adsorption at an atmospheric pressure
In the process of occurrence and development of coal and gas outburst, as far as coal quality itself is concerned, people generally agree that there are only two factors: coal strength
The greater the intensity, the less likely it is to be damaged, the greater the resistance to the development of outburst and the smaller the risk of outburst; On the contrary, the smaller the strength of coal, the easier it is to destroy, the smaller its resistance, the less energy required for crushing, and the greater the risk of outburst
WT-1 gas diffusion velocity tester is capable of releasing gas from coal
The more gas contained in coal is released in the initial period of outburst, the more gas flow carrying coal movement is easy to form in the process of outburst, and the greater the risk of outburst is; On the contrary, if coal contains a large amount of gas, but the amount released in a short time is very small, then this kind of coal contains a large amount of gas, but it is not easy to form gas flow, and the smaller its outburst risk is WT-1 gas diffusion velocity measuring instrument is the second factor to measure the above coal quality itself
The gas emission capacity of coal: 1) initial emission velocity of coal △ P, 2) Gas diffusion rate of coal sample in one minute △ D
