Coal seam gas pressure measuring instrument

  Acw-1 coal seam gas pressure measuring instrument is a product developed by Henan acw-1 coal seam gas pressure measuring instrument manufacturer in order to study and master the theory and technology of coal seam gas emission and outburst and prevent gas hazards
Using the new technology of slurry hole sealing, the real pressure of coal seam gas can be measured correctly in various mines and different rock strata
Acw-1 gas pressure measuring instrument is used for measuring coal seam gas pressure in various mines and different rock stratum conditions
Acw-1 coal seam gas pressure measuring instrument uses two groups of rubber rings to seal the hole, and injects mucus whose pressure is always higher than the gas pressure between the two groups of sealing rubber rings
The pressure mucus infiltrates into the micro cracks around the borehole, which forms a hole sealing system of rubber ring sealing mucus and mucus sealing gas
Thus, the gas leakage of the borehole is tightly sealed, and the real coal seam gas pressure is measured
Type selection description the standard configuration of the equipment has a hole sealing depth of 8m and a length of mucus sealing section of 1
8m
If a larger hole sealing depth or mucus sealing length is required, it must be explained when ordering that the equipment is designed when the set coal seam gas pressure is lower than 6Mpa, so it is not applicable when the predicted coal seam pressure is higher than 6Mpa
Technical parameters of acw-1 coal seam gas pressure measuring instrument Measured pressure: 0 ~ 8Mpa pressure of mucus cylinder: 0 ~ 8Mpa sealing depth: 8m, which can be increased to more than 20m; length of liquid sealing section: 1
