FIELD: oil and gas production.
SUBSTANCE: device for expulsion of air blocks is made in form of accumulating tank and separator successively connected with main. The tank and separator are communicated on top and below. The separator is made in form a sealed vertical cylinder in lower part of which there is positioned an inlet branch with a slanted cut directing flow of oil product tangentially to a wall, a cylinder and an outlet branch with a horizontal apron installed below the inlet branch and with diameter less, than diameter of the cylinder. Sensors of critical level are arranged on the accumulating tank; on an upper section of it there is secured a release valve actuated from the sensor of critical lever when the accumulating tank and separator are filled with air and oil product.
EFFECT: increased reliability of oil product main; efficient separation and expulsion of air blocks from main.
