FIELD: mining industry. SUBSTANCE: proposed compressor station is designed for use at completion of wells for delivering nitrogen-based explosion and fire hazard mixtures at high pressure. Station has piston air compressor of multistage design. Outlet of second stage of air compressor, through cooler and water-and-oil separator, is connected with inlet of diaphragm gas separating device through filter gang. Outlet of gas separating device is connected with inlet of third compression stage of air compressor. EFFECT: improved reliability at low ambient air temperatures, reduced overall dimensions of station. 1 dwg
