Active gas pressure measuring instrument

  Product introduction of active gas pressure measuring instrument the active gas pressure measuring instrument is developed and manufactured according to the standard of aq1047-2007 direct measurement method of coal seam gas pressure under coal mine
It adopts & ldquo; Swelling - high pressure mucus & rdquo; The two plugging and one injection hole sealing technology is used to test the gas pressure in the borehole with cracks in the mine
The active gas pressure measuring instrument is an important index for the evaluation of gas drainage area and the prediction of coal and gas outburst in the mine
The equipment has reasonable structure, convenient installation and can be reused
It is a mine production and testing equipment
Performance characteristics of the active gas pressure measuring instrument: the pressure pump is added with an accumulator to store energy, and the outlet check valve is added with a high-pressure stop valve to realize double pressure holding and avoid false hole sealing; The material has a wide range of application
Mine emulsion oil, bentonite and water supply can be used as hole sealing materials to save cost; The complete set of hole sealing devices can be recycled and reused, and the installation is fast and convenient, which can improve the gas pressure test rate& ldquo; Solid liquid & rdquo; The two-phase coupling sealing technology can be used to drill holes for crack development and improve the test accuracy and success rate; Technical parameters and specifications of active gas pressure measuring instrument: & phi; 65 * 2000 or & phi; 75 * 2000 [sealable borehole & phi; 75 - & phi; 110] (mm) pressure test range: 0-10mpa (pressure test components can be selected according to the actual mine) length of sealing section: 6-10m (customized sealing length) specification of connecting pipe& Phi; 48 * 1
