Direct Measuring Instrument for Coal Seam Gas Pressure in Underground Coal Mines

Manufacturer of Direct Coal Seam Gas Pressure Measuring Instrument for Underground Coal Mines: Zhengzhou Aidi, Warranty: One-year warranty, lifetime maintenance. MWYL-1 Active Gas Pressure Measuring Instrument

Product Introduction of MWYL-1 Active Coal Seam Gas Pressure Direct Measuring Instrument for Underground Coal Mines
The active gas pressure measuring instrument is developed and manufactured in accordance with the standard AQ1047-2007 "Direct Measurement Method of Coal Seam Gas Pressure in Underground Coal Mines". It adopts the "expansion-high-pressure viscous liquid" two-plug one-injection sealing technology, specifically designed for testing gas pressure in boreholes with fractures. The active gas pressure measuring instrument is used for evaluating gas extraction areas and predicting coal and gas outbursts. The equipment features a reasonable structure, easy installation, reusability, and is essential for mine production testing.
Performance Characteristics of MWYL-1 Active Gas Pressure Measuring Instrument
The pressure pump is equipped with an accumulator for energy storage, and the outlet check valve is combined with a high-pressure shut-off valve to achieve dual pressure retention, avoiding inadequate sealing;
Wide applicability of materials: mine emulsion oil, bentonite, and water supply can all be used as sealing materials, reducing costs;
The complete sealing device can be recycled and reused, with quick and convenient installation, improving gas pressure testing efficiency;
The "solid-liquid" two-phase coupling sealing technology specifically addresses boreholes with developed fractures, enhancing testing accuracy and success rate;
