TESTING DEVICE OF INSTRUMENTS AND ELEMENTS OF SYSTEMS OF AIR-AND-GAS AND DUST CONTROL OF WELL ATMOSPHERE Russian patent published in 2010 - IPC E21F5/00 G01D21/00 

FIELD: oil and gas industry.

SUBSTANCE: device includes testing chamber, dust supply system, system for creation of the specified air humidity and temperature keeping, device for determining the degree of dust concentration, and measurement station. Measurement station includes in-series installed thermometre, flow metre, wind metre, and pressure metre. At that, device is equipped with gas inlet system, and testing chamber is of toroidal shape and represents tight closed air line having explosion proof design inside which there located are tested instruments and elements of systems of air-and-gas and dust control, and fan with controlled speed of air jet flow. At that, measurement station is also equipped with gas analyser, pitot tube, hygrometre and aspirator. At that, each of sensors of measurement station is installed inside testing chamber through the appropriate inlet devices having explosion-proof design.

EFFECT: full simulation of real operating conditions of instruments and elements of dust and gas compound systems of mine atmosphere.
